mud pump valve body insert factory

Mud Pump Valve & Seat are made of premium alloy steel through one-piece forging and carburizing treatment processes, thereby ensuring high intensity. In addition, the precise calculation is performed and CNC machining is conducted for the dimensional matching of the valve seat and valve body working angles to enhance the service life of the valve body and valve seat. Our valve products are able to work smoothly in normal mining and digging conditions for over 400 hours.

A wide variety of mud pump valve inserts options are available to you, such as 1 year, not available.You can also choose from new, mud pump valve inserts,As well as from energy & mining, construction works , and machinery repair shops. and whether mud pump valve inserts is 1.5 years, 6 months, or 3 months.

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.

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.

Urethane bonded insert offers increased resistance to water , synthetic and oil based drilling fluids and is capable of operating in fluid temperatures of up to 220˚F (104˚C) while maintaining superior resistance to tear and extrusion

Best-all FKN valve & seat is one-piece forged valve body and full open seat, 100% interchangeable with National(NOV), suits especially for National 7-P-50, 8-P-80, 9-P-100, 10-P-130, 12-P-160 and 14-P-220 mud pumps.

Our standard valve is offered with polyurethane inserts rated for 180°F drilling-mud temperatures. We also offer a special high-temperature urethane compound as an option for high-temperature drilling conditions to 220°F and higher.
