Butterfly valves

Butterfly valves are used on pipelines of liquid-filled power transformers or on reactor fittings.
Butterfly valves enable a replacement of components without the necessity of removing any insulating liquid.
The main advantage compared to other valves is the compact and cost-efficient construction.

Butterfly valve DIN 42560 A NW 80
With welding neck flange
Nominal width 80 mm (3")
Height H = 70 mm
The throttle valve type A is designed to be welded in the transformer wall or in connecting pipes.

The flange is made of forged steel S355J2G3.
Due to a metal-metal sealing a low leakage is allowable.

Our throttle valves DIN 42560 A NW 80 fulfil the tightness requirements and operating conditions according to DIN 42560 as well as EN 50216-8.

Designs:

Groove for O-ring-sealing acc. to customer request.
Height H = 70 mm or H = 85 mm.
18 mm boring or M16 threads.
Modified welding neck acc. to customer request.
Special design up to -50°C possible.
Thrust member in several versions:
Thrust member acc. to DIN 42560, tightened.
Lockable cap, tightened.
