Medium-controlled pressure reducers are simple control valves offering accurate control while being easy to install and maintain. They control the pressure downstream of the valve without requiring pneumatic or electrical control elements.
ARSAŞ pressure reducer is piston-controlled and can be used for setting ranges up to 180 bar. Body and spring cap are made of stainless steel (316) featuring excellent corrosion resistance. The outlet pressure to be controlled is balanced across the control unit by the force of the valve spring (set pressure). As the outlet pressure rises above the pressure set using the adjusting screw, the valve cone moves towards the seat and the volume of medium is reduced. As the outlet pressure drops, the valve control orifice increases; when the pipeline is depressurised, the valve is open. Turning the handwheel clockwise increases the outlet pressure.
