Technical Data Introduction Refrigerants Shut off valves are applicable to all common non-flammable refrigerants including R717 and non-corrosive gases/liquids dependent on sealing material compatibility. For further information please see installation instruction for CSVA. These Shut off Valves are used in the Industrial Refrigeration system. Temperature range Standard version : - 46/+150�°C Pressure range shut off valves are designed for max, working pressure CSVA-2 DN-15 to DN-40 : 25 bar (362 psig) CSVA-4 DN 15 to DN 200:40 bar (580 psig) Features Housing Made of special, cold resistant steel. Valve cone Shut off valves cone can be turned on the spindle, thus there will be no friction between the cone and the seat, when the valve is opened and closed. Spindle Made of polished stainless steel so that PTFE and Graphite gaskets are not damaged. Sealing Spindle sealing is done with PTFE and Graphite gaskets assuring 100% sealing. Design Housing Made of special, cold resistant steel. Connections Available with the following connections: - Butt-weld ANSI DN15-40(B 36.10 Schedule 80) Butt-weld ANSI DN 50(B 36.10 Schedule 40) Butt-weld ANSI Socket weld (ANSI B 16.11) - DN 15 - 40 % -1% in.). Valve Cone Spindle Made of polished stainless steel so that PTFE and Graphite gaskets are not damaged. Sealing Spindle sealing is done with PTFE and Graphite gaskets assuring 100% sealing.
