Frequently Asked Questions

What is a high performance offset disc butterfly valve and how does it work?
A double offset design: the shaft sits behind the disc face and off the bore centreline, so the disc cams away from the seat the instant it starts to open instead of rubbing across it. That removes the wear that limits a concentric valve and allows far higher pressure and temperature. It gives tight shut-off with the compactness of a butterfly valve, in duties that would otherwise need a ball or gate valve.
Which body, disc and seat materials are available?
Body in SGI, WCB, CF8 or CF8M. Disc in SS 304, SS 316 or SS 410. Seat materials EPDM, Viton, Nitrile, Neoprene, Hypalon, PTFE and glass-filled PTFE up to 600 mm. Body styles are wafer, lug or double flanged short pattern, so the same valve can be specified for in-line, end-of-line or load-carrying service.
What size, pressure rating and standards apply?
DN 80 to DN 1800 in wafer, lug and double flanged bodies, rated to ANSI B16.34 / ANSI 300. Designed to API 609 Category B and tested to API 598, FCI 70-2, EN 12266 PT-1, BS 6755 and AWWA C504, with tight shut-off. Operation by handlever, gearbox, or pneumatic and electric actuator.
How does it compare with a concentric butterfly valve?
A concentric valve such as the wafer or double flanged design is limited to about PN 10–16 and its disc rubs the liner through the whole stroke, so it wears in high-cycle or high-differential service. The double offset design runs to ANSI 300, tolerates higher temperature, and lasts far longer where the valve is cycled often. It costs more, and for low-pressure water or HVAC duty a concentric valve remains the sensible choice.
Are you a manufacturer, and what are your minimum order quantity and customization options?
MVS manufactures at its own works — since 1978, ISO 9001:2015 certified — and exports across several continents. The minimum order quantity is 20 pieces. Wafer, lug and double flanged bodies, glass-filled PTFE seats, large diameters and gear or actuated assemblies are built to order.
