FLOVEL VALVES PVT. LTD. Vitthal Udyognagar, Anand, Gujarat

Wafer check valves Metal to Metal Seat tightness is as per API 598 and on specification to API 6D. Independent Torsion Spring prevents water hammer, this is a proven concept and edge over conventional valves.

These are best used at down stream of pump. Used in Heating Installation, Steam Condensate Lines, Compressed Air Discharge Lines. Used as, OEM by Boiler Manufacturers, Nitrogen and Gas Generating Equipment manufacturers, HVAC and other such equipment manufacturers use these valves extensively Design Features Design to EN 558-1 Wafer Check Valves are short travel Single Disc type. Wafer Checks with fast acting spring prevents water hammer and flow reversal in the equipment. Wafer Check Valves, with soft seat like Viton, EPDM, Buna N are available on request while Metal to Metal seat is a standard feature. Single Disc, Wafer Check Valves open at very minimum differential pressure general expressed in mm WC, please refer catalogue for precise value. Ground and Lapped Disc and body seat of Wafer Check Valves offers tight shut off as per DIN 3230. Wafer Check Valves are designed using Bernoulli’s theorem and pressure drop is designed to be minimum. Please refer catalogue for details of Pressure Drop. Size Range: DN15 to DN100 Rating : PN10, PN16, PN40 Material : Generally, ASTM Gr. WCB, Gr. CF8, Gr. CF8M but not limited. Other exotic material like, CF3M, Monel, Hastealloy, Duplex etc. on request.  

Design to API 6D and Face to Face Distance as per manufacturer’s standards. Fast acting spring prevents water hammer and pressure SURGE, this is a truly Non Slam Check Valves. Short Travel and Ultra Light weight Disc make the functions of Non Slam Check Valves possible. Quick closing and fast traveling disc are the key design features. High Velocity and Gas Flow under Compressed conditions some times reach sonic velocity and the sonic booms are detrimental to the valves. The simple but precisely calculated spring design over comes such problem. Bernoulli’s equation of conservation of energy is the solution for spring design. Velocity head exchange the energy with Pressure Head and Non Slam Check keep on performing without the fear of sonic boom and valves offer least Pressure Drop when compared to Dual Plate Check Valves.

Design to API 6D and Face to Face Distance as per manufacturer’s standards. Hub Ends are available on Dual Plate Check Valve as well as Non Slam Axial Flow Check Valves. Hub connections are used on Offshore and sub sea pipelines, where weight is a major design criteria. Hub End Valves being lighter, saves weights – saves money, as compared to ANSI Flanged End Valves. Hub Clamp are generally selected by the customer being proprietary design of Techlok, Grayloc and Vector Hub Clamp, Flovel will design and end connection suitably. Clamp connections uses 4 bolts hence quick connection and installation as compared to ANSI Flanged End valves. Clamp connection ensures proper clamping force resulting in no leakage during bending and vibrations which generally occurs in long pipelines. Seal Ring profile is precisely machined using CNC machines and special inserts.

Design to API 594 and API 6D. Metal to Metal Seat tightness is as per API 598 and on specification to API 6D. 85 Deg Door opening of Dual Plate Check Valves, offers minimum pressure drop as compared to conventional Swing/ Lift Check Valves. Independent Torsion Spring prevents water hammer, this is a proven concept and edge over conventional valves. Fire Safe Design, Cryogenic Tested design for Low Temperature and High Pressure design capabilities are the key features of Dual Plate Check Valves. Dual Plate Check Valves are available with different type of end connections like, Wafer Ends, Flanged Ends and Solid Lug type. Size Range : 2” to 48” Rating : ANSI #150, #300, #600, #900, #1500 & #2500.  Material : Generally, ASTM Gr. WCB, Gr. LCC, Gr. LCB, Gr. CF8, Gr. CF8M, Gr. CA15 but not limited. Other exotic material like, CF3M, CF8C, Monel, Hastealloy, Duplex, Super Duplex, Aluminum Bronze etc. on request.
