Refrigeration Ball Valve Withfilling Valve Compressor Valve

PLW Ball Valves PLW ball valve is a manual globe valve for use in liquid,suction and hot gas lines in refrigeration,cold storage and air conditioning plant,PLW ball valve gives maximum flow with fully open valve and maximum tightness with closed valve.I Features    No pressure drop in flow    Full open and full close mark on top of valve stem    Bi-directional flow    Argon are welded structure    Modified PTFE sealing    Inside liquid accumulation is avoided    Could be mounted on the control panel    Two types of model ball valves are available:one is equipped with the charging and inspection port (PLW174),the other is not equipped with the charging and inspection port (PLW172) Designing Function 1,Copper tube (TP2Y2) 2,Valve body (HPb59-1) 3,Sealing  (PTFE) 4,Valve bonnet (HPb59-1) 5,O-Ring (HNBR) 6,Valve stem (1Cr18Ni9Ti) 7,Brass ball (HPb59-1) 8,Ball valve connection (HPb59-1) 9,Charging valve (HPb59-1) Specification ModelMax.  working pressure (MPa)Medial temperature()Rated power of liquid1) (KW)ODF only(in)Overall dimension(in)Kv value2) (m3/h) R22R134aR502LL1L2HH1 PLW-172023.5-40~+125   1/45-5/82-7/83/82-1/27/81.96 PLW-172033.5-40~+125   3/85-5/82-7/83/82-1/27/85.68 PLW-172043.5-40~+125   1/26-1/433/82-1/27/810.58 PLW-172053.5-40~+125   5/86-1/431/22-1/27/814.11 PLW-172073.5-40~+125   7/87-3/83-5/81/23-3/81-1/428.17 PLW-172093.5-40~+125   1-1/88-1/24-3/813-7/81-3/85195 PLW-172113.5-40~+125   1-3/89-7/84-7/814-1/81-1/280.89 PLW-172133.5-40~+125   1-5/8115-17/3214-25/321-5/8121.07 PLW-172173.5-40~+125   2-1/8125-15/1615-13-162-1/8224.96 1) Rated liquid and suction capacity is based on evaporating temperature te=-10,liquid temperature ahead of valve tl=+25,and pressure drop in valve p=0.015MPa. 2) The Kv value is the water flow in m3/h at a pressure drop across valve of 0.1MPa,P=1000kg/m3.
