Mud Pump Valve Seat

Mud pump valve and seats using steel alloy forging and become, through the whole carburizing process product intensity is higher, better performance, carburizing layer is between 2.0-2.5 (mm). Through the precision of calculation and the numerical control processing to achieve the size between the valve body and seat perfect cooperation, so as to improve the service life of the body seats. Under normal conditions of use conditions for the service life of more than 600 hours. Our company can provide all kinds of pump products.

The valve and seat system consists of the valve, valve seat, valve spring, valve guide and bushing, valve cover, and valve cover seal. One of the most overlooked components of the fluid end is the valve spring. This inexpensive, small item can wreak havoc on the mud pump fluid end if it is not in proper running order. When the piston transitions from its suction stroke to its discharge stroke, the valve spring is supposed to push the suction valve down on the seat, closing the valve. A weak valve spring allows the valve to dwell in the open position longer than it should. This results in reduced efficiency because of mud flow reversal as well as the valve being slammed down on the valve seat by the returning piston stroke.

If a valve runs for 500 hours at 100 strokes per minute, the spring will experience 3,000,000 cycles. Considering its high cycling function, the valve spring should be replaced with every valve replacement.
