Solenoid Valve Products Introduction
We provide you with comprehensive solenoid valve solutions.

CH02 Series Two-chamber Direct-acting Solenoid Valve
This type of product is a new-generation metal flameproof double-chamber structure solenoid valve independently developed by Hongmen.
- The product's design structure has been optimized and improved, and an integrated circuit protection module has been added. It features high corrosion resistance, low power consumption, high stability, low temperature rise and excellent safety performance.
- Adopting high-grade coil materials and multiple protection designs to prevent coils from burning out due to excessive heat.
- The selection of high-quality materials and sophisticated structural design enable the CH02 series solenoid valves to achieve over 5 million valid operations in durability tests.
Suitable for harsh environments such as coastal areas, places with high explosion-proof requirements and SIS working conditions.

CH03 Series Pilot-operated Solenoid Valve
This type of product is a new-generation metal flameproof pilot-operated solenoid valve independently developed by Hongmen.
- The product's design structure has been optimized and improved, endowing it with features such as strong corrosion resistance, low power consumption, high fluidity, excellent stability, low temperature rise and high safety performance.
- Adopts high-grade coil materials superior to those of other brands in the market and multiple protection designs to prevent coils from burning out due to excessive heat.
- The uniquely designed air circuit structure prevents the valve from inhaling harmful ambient gas during operation, protecting the cylinder and internal components against corrosion.
- Adopting high-quality materials and a well-designed structure enables the product to perform effectively more than millions of times.
It is suitable for harsh environments such as coastal areas, scenarios with high anti-corrosion requirements and SIS working conditions. Its well-designed air circuit is more applicable to severe working conditions with corrosive gases or dust in the surroundings.
