Product Description

Main field of Walle-Seals:
· Ball valves
· Control valves
· Regulating valves
· Butterfly valves
· Sampling valves
· Gate valves
· Seat valves


Valves, which must operate with very low temperatures such as -196 °C or in the

desert,
which must be resistant against aggressive medias, hot gases and pressures of

several hundred
bars, require special solutions - seals from Walle.
This applies in particular if the operation conditions of the valves and the seals

do not permit
aging.
Walle supplies seals for the most different valves like ball valves, butterfly

valves, control and
regulating valves, gate valves etc.
Is it high temperatures +315 °C (+800 °C with Metal-seals), low temperatures or

aggressive media:
We have the correct answer for your problems.
Whether the application at the arbor respectively at the control shaft or at the

spherical sealing
surface of the ball at the butterfly or at the gate - we have a solution!


Advantages of Walle-seals:
Applicable in the housing or in the disc of butterfly valves.
In different variants and special designs from 2 mm up to 3000 mm diameter

available.
· Universal chemical-resistant
· Durable elasticity because of an integrated stainless steel spring
· Sterilisable for foodstuff or pharmaceutical applications
· Capsulated or totally sealed stainless steel spring
· Highest wear resistance and lowest friction forces
· Suitable for high and low temperatures
(-196 °C to +316 °C) (+800 °C Metal-Seals)
