Constructed of 316L Stainless Steel, Monel, and Hastelloy C-276, D-Series diaphragm process analyzer system valves are available with hand wheel, turn, pneumatic, and Fieldbus-compatible electropneumatic actuation methods. Products come in standalone (tube or pipe), multi-stream manifold, and ANSI/ISA-76 compliant SMT models with working pressure range of vacuum to 3,600 psig. Flow capacity is rated at 0.17 Cv with valve cavity volume of 0.01 cc. Diaphragm valves provide the smallest footprint in the process market today D-Series valves are constructed from only the highest quality materials to insure years of unsurpassed performance to reduce the cost of ownership.They are rated for one million-plus cycle life. Never before has the fluid process industry seen so much value combined into such a small valve Package. D-Series valves are application- flexible, diaphragm process analyzer system valves. All D-Series valves are totally free of internal elastomers, springs, bellows, packing, and lubricants in the process-wetted area.

Flosteer ?A? weir Diaphragm Valve having rugged design to incorporating the best material available is proved by easy, smooth and maintenance free operation for a long time. Extra heavy-duty casting affords high resistance to atmospheric corrosion. Flosteer diaphragm valve reduces diaphragm travel for extended service and fine control. A wide choice is available for body materials, body rubber lining, types of operation and body end connection to satisfy the need of most industrial application. High quality standards are strictly maintained, each valve being checked for size, design pressure, operation, MOC, finish etc and with in house painting. Flosteer offers diaphragm valves with various body elastomers lining like P.T.F.E., Ebonite, Neoprene, EPDM, Hypalon & Butyl and others on request. Flosteer also can supply diaphragm valve with Pneumatic Actuator / Pneumatic Cylinder for ON-OFF or control operation along with accessories like Solenoid, Limit Switch, Air Filter Regulator, Valve Positioner, I/P Converter etc.
