Valve Seat
Valve seat is used in module, at fluid end of Mud Pump. The material of valve body and valve seat is high quality alloy constructional steel.After heat treatment and numerical control machine tool manufacturing,the strength of product is enhanced.The valve body matches up to the valve seat perfectly and the working life is 2-3 times as much as ordinary products.
Valve seat has precisely ground tapered outside diameter, which is perfectly matched with pump deck taper to provide metal to metal seal between high pressure and low pressure. Rigid design of three cross arms acts as a guide to valve stem. It increases metal to metal contact between valve body and seat for distributing the impact forces over a large area. It also provides enough flow-through area essential for smooth and knock-free operation of the pump. Wear grove at the junction of bevel sealing surface and flat cross arms indicates limit of permissible wear.
