MPV Plunger check valve can be used in commercial refriger-ation system,civil and industrial air conditioning equipments.It was designed with piston close and seal,forged brass body,and max.flow rate and min.pressure drop.
The valve can ensure of correct flow direction only
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 compressor
Oversize connections provide flexibility in use
Easy disassembly and assembly design
