Project Description
Slow Start Valve
This is a differential balanced valve automatically opens the air port fully when the downstream pressure is about 50% of the upstream pressure. Without a pilot, the upstream air flows downstream through the regulation needle. When an external or pneumatic solenoid signal is generated, the valve opens the main ports to creat full flow. It doesn’t relieve the downstream circuit.
