stainless steel valve

 

Features:

1.Coil of this type is hermetic by plastic.It features moisture proof,anti-viberation,and anti-corrosive.All parts are made by stainless steel.It can be used for ammonia and Freon refrigerating system,pneumatic hydraulic and water supply system.

 

2. suitable for HFC,HCFC refrigerants and Ammonia; clean water ;</=viscosity machine oil

AC:24V  36V  110V  220V

DC: 12V  24V  110V  200V

 

4:opening pressure diff:

AC: 0.05----21bar

DC:0.05-17bar

 

5:Max working pressure :30bar

 

6:working range:---25°Ccentigrade  to   100°C

 

Operating principle

     ADF series solenoid valve is pilot type valve.When energized the coil,it lead a magnet and pick up plug,open the small orifice,course to pressure in upside of valve reduced.So the pres sure difference happen both side of diaphragm. The pressure difference lift diaphragm to open the main Orifice.When main orifice open,dia phragm shouldnt drop even if pressure difference both side of diaphragm exist too,because of flow inertia function.When coil deenergized,plug drop to close small orifice because of reset spring. Media flow to upside of valve through throttle orifice.Then balance pressure both side of diaphragm,so diaphragm return to close the mail valve.

 

Installation:

1.The valve must install in horizontal pipe line under vertical position. The flow direction must be meet the arrow direction in valve boby. 

2.Installing position should be low viberation.
   

3.Must install filter before solenoid valve in order to prevent block throttle port and lead to no function.
   

4.The coil input power must meet rated input power showed on the label.
    

5.System operating pressure must be meet open valve pertormance.
   

6.Departure coil from valve when en ergized in coil is limited in order to avoid damage the coil.
   

 7.According to valve with manual function.It must turn manual bar to open the vaNe bemre doing system air tightness, in order to avoid to damage diaphragm.
