MSC and MSCH can be used in liquid，suction and hot gas lines in refrigeration and air conditioning plant with fluorinated refregerants. MSC and MSCH can also be supplied with oversize connections providing flexibllity in the use of check valves.
The valve ensure only correct flow direction
Prevents back-condensation from warm to cold evaporator
Built-in damping piston that makes the valves suitable for installation in lines where pulsation can occur,e.g.in the discharge line from the comperssor.
MSCH is supplied with spring to △p=0.3bar.Used in refrigeration plant with comperssors connected in parallel
Oversize connections provide flexbility in use

1）△p=the minimum pressure at which the valve is completely open. The MSCH with a stronger spring is used in the dischare line from compressors connected in parallel.
2）The kv valve is the flow of water in m³ at apressure drop across valve of 1bar,p1000kg/m³
