Triple Offset Butterfly Valve

The geometric design of the GMK’s Triple Offset Butterfly Valve is the source of the third deviation. The sealing components are individually machined into an offset conical shape, which results in a right-angled cone. This assures that the device will stroke without causing any friction during its entire working cycle. Only at the very end of the closing process does the 90-degree angle, which functions as a mechanical stop, come into contact with each other. Because of this, there will be no excessive movement of the disc seat.

Benefits

• The metal sealing components are kept separate until final closure thanks to the conical shape and “cam-action” design. Because of this, valves can be sealed reliably time after time.
• Metal-to-metal seals provide a completely airtight and leak-free operation.
• The absence of any elastomers or other corrosion-prone components makes this valve suitable for harsh conditions.
• The geometric design of the valve guarantees smooth operation, and the absence of holes in the seals extends the valve’s useful life and makes it easier to maintain.
