Válvulas Auto Operadas – Redutoras e Controladoras de pressão: Válvula Redutora de Pressão DM 6901

Descrição

Self-acting 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. The DM 6901 pressure reducing valve is a piston controlled proportional control valve for lowest flow rates. The valve provides accurate control with a lightweight and compact design (minimal dimensions). Body, spring cap and medium wetted parts 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.
