UNIVERS 4200 HIGH PRESSURE CRYOGENIC BELLOWS VALVES

The Univers 4200 high pressure cryogenic bellows valves are high quality stainless steel on/off globe valves for gaseous media. Designed specifically for demanding high pressure applications, the Univers 4200 is available in a straight-way pattern and features a robust stainless steel bellows seal to ensure end-users get a high leak tightness rating through the seat and to atmosphere.

Available in both on/off globe type and non-return/check valve types, these units can be delivered as manually or pneumatically actuated valves. The manual valve is offered with a smooth and ergonomic handwheel with position indication pin. The pneumatic valve is supplied with a pneumatic actuator and electromagnetic pilot valve as standard.

The Univers 4200 is perfect for any cryogenic systems with particulary low heat inlets and high pressure requirements.
