T85 – STRAIGHT THROUGH TYPE

The T85 Straight Through Diaphragm valve is a monoblock bidirectional valve. Depending on the application, different quality of the body and rubber lining solutions can be given.

The main features of the valve:

  • 100% leak tightness performance guaranteed
  • The valve can be installed in any position
  • Produced with high EU quality components
  • Easy maintenance: Three part design allows maintenance and actuator retrotitting without removing the valve body from the pipeline.
  • Handwheel: comfortable grip, easy to use for fast operation, saves time and effort.
  • Stem designed to reduce friction for low operating torque.
  • Diaphragm: provide positive shutoff and isolates all working parts from line fluid.
  • Full flow and low pressure drop

*Valves manufactured following European Pressure Equipment Directive PED 97/23/CE

AVAILABLE CONNECTIONS

  • Face to face according DIN-3202 & BS-5156.
  • Flanges DIN PN10/PN16 Y ASA 125/150.
