The frac pump valves and seats are also called valve and seat assembly. There are valve body, valve insert, valve seat, and O-ring, these four parts consist of the frac pump valves and seats, which are very critical vulnerable parts in fracturing pumps. In higher pressure frac pumps, the mating surface of the valve body and valve seat is generally a conical surface. Frac valves and seats are the no. 1 expendables cost. 8620H or 20CrMo can be used for forged frac valves and seats. Both the valve body and valve seat would be carburized or nitrided to enhance their impact resistance and wear resistance. Polyurethane is often used as the raw material for the valve insert. Compared with rubber, polyurethane has better strength and elasticity.

This FAQ lists some questions about frac pump valves and seats for you. These FAQs shall be able to answer some queries related to the well-service pump valves and seats.

Novatech is a valves and seats manufacturer in the US. Its first welding valves were supplied nationally in 1982. As one of the oldest and strongest frac valves and seat manufacturers, a wide variety of valves & seats manufactured by Novatech are used throughout the world.

Novatech’s four streamlined guide legs full open seat valve have greatly increased the reliability and performance. The web-type valve seat was achieved to maximize the metal-to-metal bearing area. However, the loads applied to the seat webs are not uniform, the flow is not limited because of the Novatech four streamlined guide legs and the metal-to-metal bearing area is regained, the Novatech full open valve seat assembly can keep the impact loads uniformly transmitted to the frac pump fluid end. One-piece valve bodies, the insert retention groove acts as a circular channel beam to add superior rigidity to the valve body.

The plungers size defines the frac pump fluid end size. The frac pump valves and seats change with the plunger size but not all the same, some fluid ends of different plunger specs also share the valves and seats of the same size. You can find the following charts which list the general sizes of frac pump valves and seats:

The frac pump valve section is divided into the suction valve and discharge valve on the drawings. However, in order to make the disassemble and maintenance of the frac pump valve convenient, the suction and the discharge valve body adopt the exactly same design. The suction valve body is located at the lower part of the frac pump fluid end, and the discharge valve is located at the upper part of the frac pump fluid end.

By the reciprocating movement of the plunger, the suction valve and the discharge valve continuously open and close. When the suction valve keeps opening and the discharge valve closing, the liquid pours into the frac pump fluid end cylinder cavity through the suction manifold and the suction valve to complete the liquid suction. When the discharge valve keeps opening and the suction valve closing, the liquid discharge from the frac pump fluid end cylinder cavity through the discharge valve land the discharge pipe to complete the liquid discharge.

In the operation of the frac pump, the frac pump valves and seats are constantly opening and closing. Therefore, the closing speed of the frac pump valves and seats require special attention. There is a certain impact that emerges due to kinetic energy changing at the closing moment of the frac pump valves. The impact strength is related to the mass and closing speed of the frac pump valves and seats. The greater the mass and speed are, the greater the impact strength will be. The shock is the main factor that triggers the frac pump valves and seats to be damaged. It makes the allowable closing speed is a key parameter of the frac pump valves and seats design.

You need to prepare sufficient spare frac pump valves and seats parts. The quality of frac pump valves and seats directly affect the performance of the frac pump fluid end. Tianyu Mfg. serves low cost and superior performance frac pump valves and seats. As the valve body is manufactured as a one-piece, which increased resistance to abrasion and extrusion, also minimizes insert movement, leakage, and separation from the valve.

When the insert is almost damaged across the surface and caused the valve to leak, replace the insert. After replacing, no leakage keeps them working. Leakage till happened, replace the frac pump valve body. The leakage caused by the insert failure would arise the valve washout and fail easily tend to rapid erosion.

Increasing the metal-to-metal bearing area between the valve and seat is the only method to lengthen the life span of the frac pump valves and seats. The bigger this area, the bigger the area to absorb the high-impact energy from valve closing. We recommend the following tips for you as a reference.

The present invention relates to valves for use in pumps handling abrasive laden fluids and, more particularly, to valve elements for use in piston pumps utilized in drilling and servicing of oil wells.

In piston-type pumps such as triplex pumps which are used to pump drilling mud and other such abrasive laden fluids, a poppet valve comprised of a generally vertically disposed valve element and a valve seat is used to control the flow of fluid between an intake chamber and a discharge chamber. The valve element is biased, e.g. spring loaded, in the closed position. The action of the pump piston creates a suction in the discharge chamber forcing the valve element to open communication between the intake and discharge chamber, the valve element moving against the force of the spring. On the return stroke of the piston, the valve element, urged by the spring, moves down to engage the valve seat to seal off communication between the intake and the discharge chambers.

In pumps of the type under consideration, the valve element has an annular sealing surface which seals against a generally complimentary shaped seating surface provided by a valve seat disposed in the pump. Typically, the valve elements are provided with upper and lower guides in an attempt to ensure that the valve element stays aligned properly so as to allow the sealing surface on the valve element and the seating surface to properly mate when the valve element moves to the closed position. Thus, the valve element will have a central body portion which carries an annularly extending seat, the upper and lower guides projecting in opposite directions from the body portion.

Valve elements for use in pumps of the type under consideration are known wherein a resilient sealing insert is bonded or otherwise secured to a generally metallic valve element structure. However, in such valve elements, both the upper and lower guides as well as the generally centrally located body portion are metallic in nature, the upper and lower guides and the body portion generally forming a monolithic structure. Along with making the valve element top heavy with a high center of gravity, this construction increases the overall weight of the valve element.

It is therefore an object of the present invention to provide an improved valve element for use in pumps and check valves handling abrasive laden fluids or other liquids.

Another object of the present invention is to provide a valve element for use in piston or plunger-type pumps, check valves, etc. wherein the valve element has a relatively low center of gravity.

FIG. 1 is an elevational view, partly in section, of a typical valve assembly of a high pressure piston pump showing a valve element in accordance with the present invention.

Referring first to FIG. 1, a valve assembly, shown generally as 10, of a typical high pressure pump such as a piston pump, has a body portion 12 which forms an intake or pressure chamber 14 and a discharge chamber 16. An annular wall 18 has a generally frustoconical bore 20 therethrough in which is received a valve seat 22. Valve seat 22 defines a bore 24 providing open communication between intake chamber 14 and discharge chamber 16. Valve seat 22 has a frustoconical seating surface 26 and a generally cylindrical wall 28 which defines bore 24 and which, as seen hereafter, acts as a guide surface.

FIG. 5 shows a slightly modified embodiment of the valve element of the present invention. The valve element of FIG. 5, shown generally as 400, has a body portion 402 with a substantially planar top side 404 and a substantially planar bottom side 406. Projecting from bottom side 406 is bottom guide 408, guide 408 and body 402 being formed of a monolithic, metallic structure. Insert 410 has a flange portion 412 which defines an annularly extending sealing surface 414 formed from a lip 416 which is received in an annular undercut notch 418 in the periphery of body 402. Projecting from the top side 404 of body 402 is a stem 420, stem 420 being metallic in nature and, with body 402 and guide 408 forming a generally monolithic structure. Cylindrical stem 420 is received in a cylindrical, blind bore 422 formed in the top guide 424 of insert 410. As can be seen, guide 424 forms a generally cylindrical member and flange 412 comprises a monolithic structure formed of a plastic or plastic-like material having a lower specific gravity than that of the metallic material from which body 402, guide 408 and stem 420 are formed. Accordingly, valve element 400 has a lower center of gravity than would be the case if valve insert 410 were formed of metal and metallic parts as is the case in prior art structure. As in the other valve elements described, insert 410 can be bonded to body 402.

As pointed out above, the insert can be either bonded to the body portion of the valve element or it can be mechanically locked thereto. Bonding of plastic and plastic-like materials to metal parts is well known to those skilled in the art. In cases where the insert is bonded to the metallic body, it is generally not necessary to provide the insert and the body with respective receiving-projecting formations since effective bonding can be achieved across generally planar surfaces. However, the use of said such projecting-receiving formations coupled with bonding increases the overall integrity of the valve element. It will be appreciated that many projecting-receiving formations providing complimentary interengaging or interlocking portions of the insert and the metallic body can be employed. It is only necessary that the insert be secured to the body portion, whether that be by bonding, mechanical locking, or a combination thereof, such that the insert does not separate from the body when the valve element is in use.
