BALANS 7100 ULTRA HIGH PRESSURE CRYOGENIC BELLOWS VALVES

The Balans 7100 cryogenic bellows valves are straight-way valves for use on gaseous and liquid media under extremely high pressures.

These valves feature a "balanced lift" with stainless steel bellows on both sides. This means that only low actuating forces are required to operate. The design of the valve offers end users a long operational lifespan and great leak integrity to atmosphere. The valve body is machined from one piece of solid barstock stainless steel.

Whilst an installation position is not specified, the valve will deliver optimal performance when installed horizontal. End connections can are tailored according to customer specification. Unlike our other cryogenic valve models, the Balans 7100 is not suitable for installation in vacuum-jacketed pipelines.

Features and Benefits:

• High pressure balanced lift allows up to 900 BAR operating pressure
• Available with manual, pneumatic or hydraulic actuators
• Straight-way body type allows for full flow through
• Low actuating forces up to nominal pressure due to balanced valve lift
• High leak tightness at the seat area and to atmosphere
• Installation in any mounting position is possible
