CIRCOR’s new D-Series diaphragm valves are constructed from only the highest quality materials to ensure years of unsurpassed performance to reduce the cost of ownership, with a rating of one million-plus cycle life, combined with providing what is said to be the smallest footprint in the process market today.
These application-flexible analyser system valves are totally 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 0.17 Cv with a valve cavity volume of just 0.01cc.
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, TefzelŪ and PEEK™. Working pressures range from vacuum to 3600 psig (253 bar) according to actuation method, with options of hand wheel, quarter-turn, pneumatic and fieldbus-compatible electro-pneumatic.
Stand-alone tubed or piped, multi-stream manifold and ANSI/ISA-76 compliant surface mount models are offered and modular D-series valves can be easily integrated into CIRCOR’s Micro-Modular Substrate Sampling System.
