Our valves body and seat are made from alloy steel forgings and alloy steel precision castings. After carbonizing and quenching, the hardness reach HRC58-62 and have high accuracy. Our products are widely used in drilling, workover and fracturing. Variety complete, long service life. 

Used special alloy steel has been heat treatment can be bear high temperature and high pressure, suitable for high press drilling and fracturing drilling. Widely used in all kinds of plunger pump, high-pressure pump and fracturing equipment.

Valve seat used alloy steel forged.

Valve bodies have two patterns:
1. Forged body and alloy steel claw friction welding
2. Alloy steel whole precision casting. (Use special die cast a whole)
Advantages: large displacement, the full open seat easily removed. The rubber directly onto the valve body.
