  • MPV PLUNGER CHECK VALVE

    Introduction

    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.

     

    Feature

    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

    Note:The Kv Value is the water flow in m³/h at a pressure drop across value of 0.1Mpa,p=1000kg/m³.

    Main Dimension

    We have 2 types of the MPV plunger check valve,one is standard and the other is with ODF extended tube .Both of these 2 types can provide in either inch sizes or metric sizes.(Inch sizes are from 7/8”.~2-1/8”.;Metric sizes are from 22mm~54mm).All valves are with screw hole that could be installed on the panel.
