Description

T85 – STRAIGHT THROUGH TYPE

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 2014/68/EU.

AVAILABLE CONNECTIONS

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

*Other norms on request
