TURBINE BY-PASS VALVE

TURBINE BY-PASS VALVE

Product information

DN150/1400 | PN10/16/25/40/64

The turbine by-pass valve is a hydraulic controlled plunger valve that safely discharges excess flow by bypassing the turbine in hydroelectric power plants. It maintains line pressure balance during sudden load rejection and prevents water hammer. DN 150-1400, PN 10-64.

Application

  • When the turbine inlet valve closed it is using for bypass the water in penstock and save from hammer and high pressure

Control

  • Counterweight and hydraulic pistons help closing very fast with the provide of hydraulic piston will be closed

DESIGN

  • Flanges DIN EN 1092

  • Open – close and control valve

  • Circle section symmetrical flow

  • Moving linear plunger

  • Metal sealing, and EPDM sealing ring

  • V-port for high pressure difference

  • Maximum working temprature 50 °C
