A Vent Operated Check Valve, also known as a pilot-operated check valve or a pilot-assisted check valve, is designed to control the direction of fluid flow, allowing it to move in one direction while preventing reverse flow. It typically consists of a valve body with an inlet and an outlet port, a movable disc, and a mechanism to hold the disc in place. The primary purpose is to automatically open and close in response to the pressure and flow direction of the fluid passing through it.Attributes:• Prevents unintended movement or drifting of hydraulic actuators• Reduces the risk of accidents and damage Applications:A Vent Operated Check Valve acts as a load-holding valve and a safety valve that allows fluid to flow in only one direction and prevents backflow.
