Valve body and seat are forged of superd alloy steel and machined strictly in accordance with the specified process to ensure high glossiness and precise size,By use of the advanced heat treatment the products shall get high strength,high toughness and adequate hardness over HRC58.
Sealers are made of polyurethane or special rubber,which is wear-resisting,service life is long,easy to replace.
Various valve bodies and seats for all kinds of mud pumps shall be provided by us.

he fully open seat design enables removal of suction-valve seats without first removing the discharge valve seats for easy access on valve-over-valve-style fluid ends. This process can result in significant time and labor savings when only a suction-valve seat requires replacement. The seat does not have the three or four internal support webs that are common on other valve styles, and the result is a uniform distribution of pressure across the entire diameter of the fluid-cylinder valve taper, which reduces the chance of seat washout and prolongs the life of the module.

The snap-on, polyurethane insert on the standard valve is field replaceable. For the most demanding high-pressure conditions, a nonreplaceable bonded insert upgrade is available that better resists extrusion and minimizes any chance for lost-circulation material or other debris to breach the seal cavity. All standard inserts are available in polyurethane and are good for 170° to180°F (77° to 82°C) drilling temperatures. We also offer a special, high-temperature compound for drilling-mud temperatures to 200°F (93°C) and higher.
