Introduction to steam solenoid valve

Principle of steam solenoid valve:

When energized, the electromagnetic force opens the pilot hole, the pressure in the upper chamber drops rapidly, forming a high pressure difference around the closing member, the fluid pressure pushes the closing member upward, and the valve opens; when the power is off, the spring force closes the pilot hole , The inlet pressure of the electric actuator passes through the bypass hole and the chamber quickly forms a low and high pressure difference around the valve closing member, and the fluid pressure pushes the closing member to move downward to close the valve. Features: The upper limit of the fluid pressure range is high, and it can be installed arbitrarily (customization required) but must meet the fluid pressure difference condition.

Function: Suitable for two-position on-off switching of pipelines with steam, gas and liquid as media.

Structural features:

1. The gas solenoid valve has a pilot-operated valve opening structure and small volume.

2. The main valve and pilot valve are sealed with PTFE molded material, which is resistant to high temperatures and has a long life.

Scope of application

The high temperature solenoid valve is suitable for installation on gas and liquid pipelines to control the switch pipeline, adjust the opening degree or prevent the medium from flowing back. It has the characteristics of high temperature resistance, condensation resistance and wear resistance. The action is not affected by condensate, and it is more suitable for pipelines with large pressure differences.
