Diaphragm valves

CIRCOR’s new D-Series diaphragm valves are application-flexible analyser system valves that are free of internal elastomers, springs, bellows, packing and lubricants in the wetted area while metal-to-metal seals ensure that no leakage of process stream is released into the atmosphere. Flow capacity is 0.17Cv with a valve cavity volume of 0.0cc. Available in standard 316L stainless steel, Monel and Hastelloy C-276, the valves offer working temperature ranges from -40 to +260°C depending on seat material choice from PCTFE, Polyimide, Tefzel® and PEEK™. Working pressures range from vacuum to 253 bar according to actuation method, with options of hand wheel, quarter-turn, pneumatic and fieldbus-compatible electro-pneumatic.
