D-Series diaphragm valves are constructed from only the highest quality materials to ensure years of unsurpassed performance to reduce the cost of ownership.
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 0.17Cv with a valve cavity volume of just 0.01cm3.
Available in standard 316L stainless steel, Monel and Hastelloy C-276, the valves offer working temperature ranges from -40 to +260C depending on seat material choice from PCTFE, polyimide, Tefzel and Peek.
Working pressures range from vacuum to 253bar, according to actuation method, with options of hand wheel, quarter-turn, pneumatic and fieldbus-compatible electropneumatic actuators.
Stand-alone tubed or piped, multistream 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.
