Several tips for you to select correct solenoid valve by XHnotion Pneumatic
A White Paper From XHnotion
We make the difference.
A solenoid valve is basically a motorized valve and are most frequently used to control the flow in a pressurized liquid, gas or air system, and can have a variety of operations within a system, such as turn on/off, release, dose, distribute or mixing of fluids. Simply speaking, it is a method of converting electrical signals into pneumatic functions. So here is some tips for you to select right solenoid valves.
What matters1. Voltage: 12VDC, 24VDC, 110VAC, 220VAC2. Operating Pressure: 0-200bar3. Fluids: air, gas water, oil, steam4. Body Material: brass, stainless steel, plastic5. Acting Way: normally closed, normally open6. Connection Type: thread, flange7. Orifice Diameter: 2.5~50mm8. Seals: NBR, EPDM, silicone, PTFE9. Port Size: 1/8"~2"10. Coil: DIN connector, wire leads
Direct Acting: Direct acting valves have an armature tube that acts directly on the main orifice to control the flow of fluid. Because of this, direct acting valves do not need a minimum pressure to operate.
Pilot Operated: Pilot-operated valves have an armature that acts on a pilot orifice, which in turn operates the flow of fluid. Because of their particular configuration, pilot-operated valves need a minimum differential pressure to operate.
Direct Lift: Direct acting valves have an armature tube that acts directly on the main orifice to control the flow of fluid. Because of this, direct acting valves do not need a minimum pressure to operate.
Types of solenoid valve

To choose the right valve, there are 2 main parameters to consider.
