These series L2 EMERSON Numatics 3 position, 4-way open centre double pilot valves can be found on pneumatic based systems involving high flows. The pressurized air mostly moves the pilot operated valves. When the set pressure is achieved, the valve opens and the pressure is released.
The flow directing element of the valve changes when pressured fluid meets the valve piston. Main benefits include higher shifting forces without the impact or wear that a manually operated valve would experience. Pilot controlled valves can be installed on any distant site where pressure needs to be piped.
