Price of gas solenoid valve

Price of gas solenoid valveAerospace, shipbuilding, petrochemicals, power equipment, industrial furnaces, boilers, gas pipelines, gas treatment plants, gas stations, gas leak alarm systems, safety protection systems, fire alarm systems are widely used for the safety protection of flammable and explosive medium pipelines in cities or factories. When potential accidents are discovered, they can be quickly cut off to prevent the occurrence of malignant accidents in a timely manner.

3、 Classification of solenoid valves: Solenoid valves can be classified into three major categories based on their principles:

1. Direct acting solenoid valve: Principle: When powered on, the solenoid coil generates electromagnetic force to lift the closing member from the valve seat and open the valve; When the power is cut off, the electromagnetic force disappears, and the spring presses the closing member against the valve seat, causing the valve to close. Characteristics: It can work normally under vacuum, negative pressure, and zero pressure, but the diameter generally does not exceed 25mm

2. Distributed direct acting solenoid valve: Principle: It is a combination of direct acting and pilot operated principle. When there is no pressure difference between the inlet and outlet, after being energized, the electromagnetic force directly lifts the pilot small valve and the main valve closing member upward in sequence, and the valve opens. When the inlet and outlet reach the starting pressure difference, after being energized, the electromagnetic force pilot small valve, the lower chamber pressure of the main valve rises, and the upper chamber pressure drops, thereby using the pressure difference to push the main valve upwards; When the power is cut off, the pilot valve uses spring force or medium pressure to push the closing member downwards, causing the valve to close. Features: It can also operate under zero pressure difference, vacuum, and high pressure, but with high power, it must be installed horizontally.

3. Pilot operated solenoid valve: Principle: When powered on, the electromagnetic force opens the pilot hole, causing the pressure in the upper chamber to rapidly decrease, creating a high and low pressure difference around the closing member. The fluid pressure pushes the closing member upward, and the valve opens; When the power is cut off, the spring force closes the pilot hole, and the inlet pressure quickly forms a lower and higher pressure difference around the closing valve through the bypass hole. The fluid pressure pushes the closing valve to move downward and close the valve.

Electromagnetic valves can be divided into six sub categories based on differences in valve structure, materials, and principles: direct acting diaphragm structure, step-by-step heavy plate structure, pilot diaphragm structure, direct acting piston structure, step-by-step direct acting piston structure, and pilot piston structure.
