// Valve description : The main parts of the valve are body, disc, trunnion, shaft, stuffing box, gearbox, bearings and actuator. These valves are bidirectional sealing valves. Special sealing geometry & seal shape ensures zero leakage & free movement of disc over more than 95% of travel in case of double eccentric butterfly valve. The triple eccentric butterfly valve has unique features of zero friction between valve and seat with very low operating torque.
// Operation : Electrical actuator with gear box, hydraulic cylinder, pneumatic actuators. Emergency manual control is possible for electric and pneumatic actuators.
// Maximum Operating Pressure : 0.5Mpa
//Maximum Operating Temperature : upto 200°C (with rubber seal), upto 500°C (with laminar seal)
// Type of Sealing : Rubber sealing and laminar sealing (Metal to Metal).
// Maximum Size : 3500mm for double eccentric and 2200mm for triple eccentric.
// Connections to Piping : Flanged Ends.
// Installation : Into the horizontal & vertical pipelines with shaft in horizontal or vertical position.
// Testing : Operation Test, Body Test, Seat Leakage Test.
// Applications : The Double eccentric butterfly valve is used for shut off applications of Air / Gas and Waterlines and where as the triple eccentric can be used for shut off as well as regulating duty applications.
