Brief Specifications:

Double Flanged Butterfly Valves offer a single piece body design with flanges at either end to provide greater resistance for dead-end service. This particular TTV Butterfly Valves’ main strength is its face to face interchangeability and has been designed to meet international standards for not only Butterfly Valves but even some Gate Valves giving the End User far more options when it comes to replacing existing valves in the line. Replacing some antiquated Gate Valves with Butterfly Valves in certain applications is now common practice. They are generally easier to install due to the lightweight body design, easier to actuate both electrically or pneumatically and are more readily available.

Double Flanged Butterfly Valves concentric design features an elastic, vulcanized seat that takes the shape of both the inside and partially outer side of the body of the valve to form a perfect seal with relevant pipe flanges.

A single piece shaft design brings high strength and engineering with direct mount capabilities for actuation assemblies. The “Dry Shaft” feature ensures fluid is again isolated from both the shaft and the body of the butterfly valve.

Hand Polished Butterfly Valves

Hand polished, streamlined discs produce a much greater Cv than other butterfly valves on the market resulting in low-pressure drops and reduced energy costs while maintaining a bi-directional bubble tight seal in the closed position. Low operational torque reduces the costs of gear, pneumatic and electric actuation with low friction contact extending the life of the self-cleaning seal.

Replaceable seals offer flexibility and cost-effective solutions without the cost of a complete new valve. Reducing lead times and unnecessary downtime for End Users.
