Product Summary

A conical check valve is a type of check valve with a conical body. It is a check valve which has a presettable cracking pressure.

The check valve employs a spring-loaded valve element in which the compression spring and valve element are held into position in the valve body by means of an apertured plug. This mode of flow regulation is required to prevent return flow, to maintain prime after the pump has stopped, to enable reciprocating pumps and compressors to function, and to prevent rotary pumps and compressors from driving standby units in reverse. This may be done either manually or automatically. Manual operation also includes the operation of the valve by means of a manually controlled power operator. The valves discussed here are manually operated valves for stopping and starting flow, controlling flow rate, and diverting flow; and automatically operated valves for preventing back flow and relieving pressure.
