The valve seat often cracks inside of the seat flange area. Once the seat cracks, a wash point occurs, washing out the fluid end. Also, changing valve seats are one of the biggest maintenance headaches.

As a result of our extensive research, we have transitioned to our new patent-pending Super Seat® design. The Super Seat® is in full compression AND has tungsten carbide only where it matters - in the strike face or metal to metal seal area.

The new Super Seat® design enables us to offer a 4 series valve seat for only $89 and a 5 series seat for just $98! And, since there’s no flange to break, wash points in the fluid end are a thing of the past. This new seat will reduce downtime and protect a failure that happens much more often than it should.

The Patriot Harsh Duty Valve is a bonded urethane valve that will hold up in the most extreme drilling environment. The Patriot HD offers the strongest urethane bond of any valve for increased service life and a stronger seal.

Superior Performance, Long Run Life, Excellent Abrasion Resistance and Sealing Surface coupled with the highest rated chemically resistant urethane make the Patriot HD Valve an excellent choice for any drilling application.

The Caliber® 4-web valve and seat are designed for today’s high pressure drilling conditions. Each piece is forged from a single piece of proprietary, high-strength alloy steel and is case hardened to precisely controlled levels. We have molded our high temperature, high impact resistant urethane to the valve body in order to eliminate the existing gap you will find on replaceable insert type valves.

The 4-web design holds the valve weight to a minimum by increasing the load bearing area. In order to allow quick flushing of solid matter we use a steep angle that also increases the metal-to-metal sealing area. Each part is individually inspected to ensure performance and satisfaction.

Mud pump valve body and mud pump valve seat were produced according to API Specs as well as ISO9001 quality system by our company, were used high quality alloy steel 40CrNiMo、20CrMnTi, processed with overall forging and carburizing, the surface hardness HRC≥60; They were produced under accurate calculation and numerical control lathe, which makes dimensions of valve body and seat perfectly match each other, also were used many times by land and offshore platforms. The service life of valve body and seat are 4-5 times more than ordinary ones, which improves the working efficiency and decrease the cost and working strength.

Mud pump valve assy include valve body, valve seat, valve insert (valve rubber ). As to valve insert (valve rubber) material, we can provide Nitrile rubber (NBR) valve insert, polyurethane (PU)valve insert, compound polyurethane and HNBR.

The fluid end of a duplex or triplex pump offers hundreds of opportunities for error. The results of an error in such a high-pressure system can mean (1) expensive downtime on the pump and maybe the entire rig, (2) expensive repair-replacement, and (3) possible injury or death of a crewman or a company man. Under the laws of nature, pump pistons and liners will wear, and there will be some corrosion and metallurgical imperfections, but the majority of pump failures are manmade. Theoretically, thorough training and retraining should avoid most mud pump problems. Realistically, a critical failure analysis during repair will be necessary to determine how to correct the failure. Telltale signs of trouble are distortion of piston rods, frayed piston polymer, discoloration, odor, hard-to-remove piston, rod cracks, pitting, total fracture, valve seat wear, and unsuitable external appearance.

abstractNote = {Failure of a liner seal is one of the more critical failures on a mud pump because this seal interfaces with the pump body. Therefore, failures, usually damage the pump body, leading to repair or replacement of the fluid end itself. One of the more common liner seal problems involves counter-bore-type seals. This type of seal is easily affected by two aspects of the problem that are found in the mud pump fluid end-wear and foreign matter in the seal groove. Factors relative to difficult liner removal are discussed. Piston damage, careless seal installation and corrosion damage are also examined.},

According to the use of mud pumps in the jurisdiction, valve box puncture, bearing burnout, and abnormal noise are all frequent failures that affect the normal use of mud pumps. Therefore, carefully studying the causes of the above problems plays a key role in prolonging the service life of the mud pump.

The drilling mud pump valve box is an important component of the hydraulic end of the mud pump, because the working conditions of the mud pump valve box are harsh working environments such as high pressure, high sprint, and high abrasiveness.

The main reasons for the leakage of the valve box of the mud pump are: long-term high-pressure use, the material of the valve box is fatigued, and when penetrating cracks occur, the current conditions cannot be repaired.

Because the working conditions of the drilling pump valve are very bad, the valve disc and valve seat of the discharge and suction valves have an impact in each flush. The higher the pump speed, the greater the impact and scour wear.

Because of this, the working frequency of the drilling pump is not very high. Even so, the working life of the mud pump valve is still very short, and it is one of the weakest links in the drilling pump. The valve disc and valve seat need to be replaced frequently during work.

According to the valve box used and maintained, most of the puncture leakage occurs at the joint surface of the valve seat and the valve box. Therefore, it is necessary to replace the valve seat regularly.

At the same time, check the inner and outer walls of the valve box. When installing and replacing the valve disc and valve seat, the valve seat must be cleaned to ensure that the fitting surface of the mud pump valve box and the valve seat is clean and free of contamination, and there can be no anti-rust oil on the valve seat, and do not apply any oil stains.

Through correct installation and replacement of valve disc, valve seat and careful inspection of valve box, the fatigue limit of valve box can be reduced, thereby prolonging the service life of mud pump valve box.

When there is a puncture in the valve box, our current repair method is welding repair, but the effect is average. Generally, if the surface is punctured, or there are obvious cracks, it can be used through the car and then welded to the original size.

However, penetrating cracks cannot be seen with the naked eye. Now we basically rely on experience in repairs, and it is difficult to fundamentally solve the problem. Many valve boxes are dark wounds that cannot be determined penetrating during maintenance. Its use can be determined from the integrity of the surface of the valve box of the mud pump.

Some valve boxes with good appearance will be completely punctured as long as they are exposed to high pressure during the specific use process. Therefore, many repaired valve boxes will be seriously punctured within a few days after being put into the well, causing rework and making us overhaul. The service life of the latter pump head is significantly shortened.

Also known as Nova Tech Valve or Roughneck Valve or High Pressure Valve. Full open Seat & wing guided Valve design features a large metal-to-metal bearing area for long life, directly casted urethane insert on valve body results in a perfect round shape that prevents premature failures of the insert. The insert is casted around the serrations, thus failure due to tears from the serrations are eliminated Most importantly the insert is not stretched over the valve during installation; there are no residual stresses left, to shorten insert life.
