Solenoid valves for fluids - F300 Series FLUID CONTROL Overall dimensions and information are provided solely for informative purposes and may be modified without notice. 1 General details PNEUMAX offer a vast range of solenoid valves in brass and stainless steel designed to control air, water, steam and all fluids that are compatible with the materials (body and seals) used in the range. The solenoid valves are 2 or 3-way, normally closed, normally open, general service, direct acting or servo-actuated, with connections available in NPT & BSP threads from G1/8” up to G2”, with a working pressure range from vacuum to 100 bar. Solenoid valves are available with coils that conform to CESI 03 ATEX 344 certification for explosive environments. Our technical office ensures the highest standard of skill and understanding for the widest variety of applications, ensuring that the best possible solutions are found. Versions manufactured Direct action 2-way: 2-way solenoid valves have an input connection and an output connection machined in the valve body, the orifice being intercepted by the plunger mounted in the core tube. Direct action 3-way: 3-way solenoid valves have an input and an output connection in the valve body and an exhaust connection fitted in the fixed core. The input and exhaust orifices are intercepted directly by the plunger fitted within the core tube. They can be normally closed (2/2 NC) , in this case the fluid is in- tercepted by the plunger at rest, with electricity applied, the input orifice is opened and the media reaches the intended use. They can be normally open (2/2 N 2 ) , in this case at rest the orifice remains open without electricity applied, the media reaches the intended use. When electricity is applied the input orifice closes. Performance in both cases depends solely on the magnetic field produced by the solenoid coil. The solenoid valves can also work at zero pressure. They can be normally closed (3/2 NC) and in this case, at rest, the incoming fluid is intercepted by the plunger and output port in connected to the exhaust port Applying electrical power, the input orifice is opened and feed is supplied to the output. Exhaust is closed. They can be normally open (3/2 N 2 ) and in this case, at rest, the input orifice is open without electricity applied, the media reaches the intended use. Exhaust is closed. Applying power, the input orifice closes and the output dischar- ges through the exhaust port. Performance in both cases depends solely on the magnetic field produced by the solenoid coil. The solenoid valves can also work at zero pressure.
