Double Offset Butterfly Valve Distributor Supply With Worm Gear

Confirm nominal diameter, nominal pressure, flange drilling, face-to-face dimension standard, applicable medium, actuator requirement, and inspection standard. For distributor stock, it is also useful to separate common sizes from project-only sizes so packing and documentation can be prepared correctly.

The product page lists BS EN593, BS5155, API609, and DIN3354 for design, ISO 5752, BS EN558, API609, DIN3202, and ASME B16.10 for face-to-face dimensions, AWWA C207, DIN 2501, and EN1092 for flange connection, and EN12266-1, API 598, ISO5208, and JIS B2003 for inspection and testing.

The double offset plate reduces friction at the sealing pair during operation. For procurement teams, that structure supports lower operating torque, reduced seal wear, and a more practical valve choice for repeat waterworks, marine, and industrial pipeline projects.

Yes. The product information states that the valve plate sealing ring can be replaced. This matters for maintenance planning because distributors and contractors can consider seal accessibility when matching the valve to long-running water, sewage, or seawater lines.

The listed applicable media include fresh water, sewage, sea water, air, and similar service conditions. Final selection should still check medium concentration, temperature, pressure, and corrosion conditions against the project specification.

Concentric butterfly valves are common for standard low-pressure water lines, while a double offset butterfly valve is usually reviewed where lower seal friction, larger diameters, and stronger long-term shutoff behavior are important. The right choice depends on size, pressure class, operating frequency, and installation standard.
