![]() ![]() Direct acting valvesĭirect-acting pneumatic solenoid valves have a coil which magnetically opens the valve without the need for outside pressure. ![]() In terms of operation, pneumatic solenoid valve types are classified by whether they are direct acting valves or pilot-operated (indirect) valves. The two-way valve is the most common pneumatic solenoid valve type. What are the key pneumatic solenoid valve types? Curious to find out more about solenoid valves? Read our blog post to find out more. Industries that use pneumatic solenoid valves can be from industrial hydraulics, pneumatics to household plumbing and heating. Solenoid pneumatic flow control valves can be used in any application that requires the flow control of a gas (usually air). This means that pneumatic control valves are useful in situations where you require automated actuation, fast valve response times or in fail-safe systems. Pneumatic solenoid valves require a constant flow of current to remain open as without the current, the electromagnetic field disperses and the valve returns to its original position. This allows electronic flow control of liquids or gases. Solenoids are used in many applications where automated switching and valves are a feature.Ī pneumatic control valve applies the linear motion generated in the solenoid to a piston or actuator within a valve. By placing a ferrous metal bar within the coil and applying a current, the electrical energy is converted to mechanical energy the bar is propelled in linear motion by the resultant magnetic field. When electricity is passed through the coil it produces a magnetic field at right angles to the current flow. Its main feature is an electromagnet consisting of a single coil of wire in the shape of a tube. What are pneumatic solenoid valves?Ī solenoid valve is an electromechanically controlled valve. Solenoid valves are used widely in pneumatics as they allow fast responses, automated actuationĪnd are ideal for fail-safe systems due to their immediate reaction to a cut in the energy source. ![]()
