It is a part of the Norgren RA/8000 series, which includes both normally-closed and normally-open valves for controlling, throttling, and modulating air in compressed air systems. This particular model is made of stainless steel for corrosion-resistance, and has an inlet and outlet port size of 100mm. It is designed for use in applications requiring accurate pressure and flow control, such as fluid control, pneumatic systems, cooling systems, process control and instrumentation. It can withstand pressure from 0-10 bar (145 psi).
