GZYS American standard high-pressure solenoid valve

Product introduction: GZYS high-pressure solenoid valve is an industrial equipment controlled by solenoid. It is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. The high-pressure solenoid valve blocks or leaks different oil drain holes by controlling the movement of the valve body. High pressure solenoid valves are suitable for compressed air, water, low-pressure steam, gas, coal gas, natural gas, oil, strong acids and alkalis, and slightly corrosive media.

Applicable fields

High pressure solenoid valves are used in various medium temperature, high temperature, normal pressure, and high pressure applications, and are suitable for automatic control of pipelines such as medium and high temperature hot water, heat transfer oil, high temperature steam, saturated steam, and superheated steam; Widely used in military, aerospace, shipbuilding, nuclear, petrochemical, power, chemical, light industry, machinery, scientific research, industrial kilns, drying equipment, water supply and drainage, fire protection, food and medical, cleaning equipment, fountains, pipeline media automation control and other fields. It is a product for automation control engineering, project renovation, and equipment matching.

working principle

Normally closed:

When the coil is powered on, the pilot valve core is attracted, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve is opened; When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the valve chamber is pressurized by the piston throttle hole and the thrust of the reset spring, and the solenoid valve is closed.

Normally open:

When the coil is energized, the pilot hole closes, and the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, causing the solenoid valve to close. When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole opens, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve opens.

Installation Instructions

1. During installation, it should be noted that the arrow on the valve body should be consistent with the flow direction of the medium. It cannot be installed in places with direct dripping or splashing water. The solenoid valve should be installed vertically upwards.

2. The solenoid valve should ensure normal operation within a fluctuation range of 15% -10% of the rated voltage of the power supply,

3. After the installation of the solenoid valve, there should be no reverse pressure difference in the pipeline. And it needs to be powered on several times to reach the appropriate temperature before it can be officially put into use.
