Stop Check Valve

Introduction : 

• Refrigerants : Applicable to all common non flammable refrigerants including R717 and non corrosive gases/liquids dependent on sealing material compatibility.
• Standard version : - 46/+150°C
• Pressure range : Range The valve are designed for max. working pressure 40 bar g (580 psig).

Features

The valve Designed to open at a very low differential pressure of 0.04 bar (0.58 psig) Designed with a built-in damping chamber preventing valve flutter, due to low refrigerant velocity and low density Easy to disassemble for inspection and service Internal back seating enables replacement of the spindle seal whilst the valve is active in under pressure Optimal flow characteristics ensuring quick opening to the fully open position.

Housing : Made of special, cold resistant steel.

Valve cone : The valve 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.
