Design innovation has been the driving force for Weir Novatech and its rigid full open valve and seat. Novatech offers valves and seats for all major well service and mud pump applications including work-over, cementing, acidizing, fracturing and drilling. Weir Novatech valves and seats are manufactured by combining the advantages of forged steel to assure impact strength and precision casting to maximize flow and minimize fluid turbulence. All Weir Novatech valves and seats are manufactured to rigid quality control standards. Weir Novatech is the leader in full open valve and seat technology, providing the first drilling valve and seat in the industry rated for continuous service at 7500 PSI. Available in API 4, 5, 6, 7 and 8 sizes, plus seats for all OEM tapers. Weir Novatech manufacturers the strongest and most reliable valve and seat in the industry.

Manufacturing utilizes the latest technologies to produce accurate and uniform parts. All products offered are either OEM or completely interchangeable. All fluid end accessories are available for most triplex and duplex mud pumps.

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.

TianyuMfg provides 100% interchangeable frac valves and seats with Novatech’s. Our valves and seats are manufactured by high-quality alloy steel and which is forged integrally. The developed high, medium, and low-end products suit different working conditions for you to choose, including work-over, acidizing, cementing, fracturing, and drilling.

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:

Tianyu Mfg. Provides various kinds of frac pump valves and seats. Contact TianyuMfg sales engineer to get the most appropriate valves and seats for your pumps.

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.
