Check valve sealing for high-pressure liquid ammonia pumps
Thread Content
Colleagues, for the high-pressure liquid ammonia pumps you are using, how many different types of sealing mechanisms are available for their check valves?
The check valve in high-pressure liquid ammonia pumps typically uses a conical valve core, with a slanted surface for sealing against the valve seat. The valve body and the valve chamber are usually sealed using O-ring seals.
