Vridspjäll Tritec (TT1 Triple Offset Butterfly Valve)
Vridspjäll Tritec (TT1 Triple Offset Butterfly Valve) Image

In comparison to conventional valves, butterfly valves are smaller and lighter, making them ideal for space conscious plant designs, particularly FPSO’s and offshore rigs. However, a standard butterfly valve does not have the control or shut off requirements for high pressure, high temperature applications. The Triple Offset design moves the centre of rotation within the valve and utilises an ellipsoidal sealing geometry. This allows a wide range of metal seating materials to be used, providing zero leakage performance on high temperature, high pressure and firesafe applications.
Size Range: DN50 – DN1650 (2″ – 66″)
Pressure Rating: Class 150-Class 2500
Body Patterns:Wafe,Lugged,DFSP,DFLP, BWE, Hub, etc
Body Seat: 316SS, Graphite
Body Materials:WCB,304,316,Hastalloy, Inconel, etc.
Disc Materials:WCB,304,316,Hastalloy, Inconel, etc.
Temperature Rating:-46°C to +750°C
Certification:API6FA, API607
Operation:Manual, Electric,Pneumatic, Hydraulic.
