What is a Solenoid Valve?
Solenoid Valves is an electromechanical device that is used to change the function of a valve from open to close to control the flow liquid or gas.
There are typically 5 types of Solenoid Valves, and we shall walk you through on it below:-
|2/2 Direct Acting Solenoid Valve||This valve has a thread size of 1/8” – ½”. Its rapidly responsive, has a zero pressure open and small office. When the valve opens in a direct acting valve, the coil hypnotically acts in a direct action, elating the shaft and the seat of the valve without being liable on outside pressure. If the solenoid coil is energized, there will be a direct influence on the position of the valve.|
|2/2 Semi-Direct Solenoid Valve||
This valve has a thread size of 1/8” – 4”. This valve has a combination of direct acting and pilot operated. Its working pressure is from 0 – 10 bar and has a very low pressure start.
|2/2 Pilot (Indirect) Solenoid Valve||This valve has thread size of ½” – 4”. It has a 0.5 bar pressure start and maximum working pressure to 20 – 500 bar. This valve typically opens slower than direct acting valves. This valves are like indirect valves and also features a transferrable membrane with a small orifice and pressure chambers on both sides. The solenoid plunger is straight connected to the membrane. When the plunger is lifted, it rightly lifts the membrane to open the valve.|
|2/3 Solenoid Valve||This valve has a working pressure of 0 – 8 bar and is used to operate single – acting actuators. It has three ports:- port 1 as the valve inlet, port 2 as the outlet and port 3 as the exhaust.|
|2/5 Solenoid Valve||These valves have 4 or more port connections. It provides a positive two directional actions. Four-way valves are generally used to offer on-off operation of double-acting valves with a dual-acting cylinder or actuator. When the solenoid valve is de-energized, it sends a full air supply to one side of the actuator and consumes the other side to the atmosphere.|
