Brief Specifications:

Lugged Butterfly Valves are commonly used in piping systems as a dead end service Valve or where regular/predicted disconnecting of the pipe on either side may need to be removed for maintenance and installation without disruption to both sides of the line. The single piece body with threaded lugs is installed using two sets of bolts (One set for each flange) and enables the installer precise self centering capabilities of the valve due to the body design between flanges. This TTV Butterfly Valve is suitable for both on and off or throttling applications.

TTV Butterfly Valves concentric design features an elastic, replaceable or 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, 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.
