Excess Pressure Valves
Unique to Eclipse, the Excess Pressure Valve is a self-actuated valve that closes when the system pressure increases above a set point. Likewise, it opens when the pressure drops below that set value. This makes it useful for PRS bypass applications, pressure reducing regulator bypassing, and other uses.
Normally, an automated bypass valve in a PRS requires a number of elements to work. It needs a ball valve, actuator, solenoid, low pressure supply + tubing, pressure transducer and PLC programming. The Excess Pressure Valve allows all this to be replaced with one valve, simplifying the system, reducing the number of potential failure points as well as a number of other benefits. It also acts as a safety shut-off valve, preventing overpressurisation of low-pressure systems downstream of the bypass valve.
