Valve Assy

1. Valve body are combined of Valve body,valve seat &valve insert 2. Used in triplex single action mud pump fluid end

Valve Assembly 

The main material of Valve Assembly is high quality alloy steels,such as 20CrMnTi, 20CrNiMo.The Valve Insert was made by newly high molecular materials,to make the mud pump spares to resist high-temperature,high-pressure,anti-friction and sulfur corrosion.

  The valve assembly made by Dezhou Rundong Petroleum Machinery Co.,Ltd. ranks in the top class of international level.
