Balans 7100
Pneumatic cryogenic globe valve
Balans 7100: Straight valve for gaseous or liquefied media for cryogenic systems under high pressure. Balanced lift with stainless steel bellows on both sides. Low actuating forces required. Compact and space-saving pneumatic actuator. Long life and high leak-tightness to outside. The valve body is machined from one piece of solid stainless steel. Installation position not specified but preferably horizontal. End connections according to customer specification. Limit switches, solenoid valves and further components are available on request.
Not suitable for installation in vacuum-jacketed pipes!
