Frees 1200 TD
Pneumatic cryogenic control valve
Frees 1200 TD: unique cryogenic valve with minimized clearance volume for vacuum insulation and any installation position. Suitable for dangerous, toxic or acid fluids and with very low heat inlet due to the minimized clearance volume. Straight or angle valve configuration with stainless steel bellow for long life and high leak-tightness to outside.The valve body is machined from one piece of solid stainless steel. End connections can be supplied in butt-welded execution or according to customer specification. Includes regulating diaphragm actuator and IP-positioner.
