There are two primary methods used within hydraulic valves. Some control hydraulic fluid flow by using a spool, bore and different ports, while others use one or more poppet valves. Both of these types of hydraulic valves are designed to control or change the direction of hydraulic fluid flow.
The balanced bellows type relief valve is normally provided with 1/2 size port which is normally open to atmosphere (must be kept open for proper functionality of relief valve). As per our project philosophy, we need to route the port vent to safe location with hard piped connection.
