Diaphragm Valve, Metal

Transcription

1 Diaphragm Valve, Metal Construction The GEMÜ pneumatically operated 2/2-way diaphragm valve has a low maintenance membrane actuator which can be controlled by inert gaseous media. Features? Suitable for inert and corrosive* liquid and gaseous media? Insensitive to particulate media? Valve body and diaphragm available in various materials and designs Advantages? Optional flow direction, will seal in either flow direction up to full operating? Good flow capability? Accessories: - Stroke limiter - Optical position indicator - Manual override - Pilot valve with manual operation - Electrical position indicator? Pneumatic or electro-pneumatic positioners * see information on working medium on page 2 Sectional drawing

MG = Diaphragm size K V values were measured with cast iron body and EPDM diaphragm. Higher operating s on request. K V values shown are valid for unlined valve bodies. K V values for lined valve bodies are lower depending on the lining. - Control Actuator 0/F*, 1/F*, 2/F* - Control Actuator 3/F*, 3A/F* - Control Actuator 4A/F* Control in bar Control in bar Control in bar in bar in bar in bar Note: In the above diagrams, for normally open actuators (c.f. 2) the minimum necessary control is given in accordance with the operating. * For double acting actuators (c.f.3) the necessary control can be 1 bar less than that shown in the diagrams. ** For double acting actuators (c.f.3) the necessary control can be 0.5 bar less than that shown in the diagrams. 2
