Solenoid valve

An electromagnetic valve is a basic automated component that uses electromagnetic force to control the on/off state or flow direction of fluids (gas, liquid, etc.). It is widely used in industrial automation, home appliances, medical equipment and other fields.

Pressure regulating valve

A pressure regulating valve is an automated valve used to control the pressure of fluids (gas or liquid). It can regulate fluctuating inlet pressure to a stable outlet pressure, ensuring that downstream equipment operates under safe and constant pressure.

Air-fuel proportional valve

An air-fuel ratio valve, also known as a gas/air ratio regulating valve, is a high-precision control device used in industrial combustion systems. Its core function is to precisely adjust the flow rates of gas and combustion air according to a preset optimal ratio based on real-time operating conditions, ensuring that the burner always operates at the optimal air-fuel ratio.

Vent valve

A vent valve, also known as a relief valve, release valve, or exhaust valve, is an automatic safety device installed on pipelines, containers, or equipment. Its core function is to automatically open when the internal pressure of the system abnormally rises and exceeds a set safety value, releasing some of the medium (gas, liquid, or a gas-liquid mixture) into the atmosphere or a recovery system, thereby reducing pressure and protecting system safety. Once the pressure returns to normal, the valve automatically closes to prevent further leakage of the medium.

Manual valve

A manual regulating valve, as the name suggests, is a valve used to manually adjust the flow, pressure, or direction of a medium (liquid, gas, steam) in a pipeline. It is the most basic, common, and widely used type of valve.

linear valve

Linear valves, also known as direct-stroke valves, are one of the most important types of control valves in industrial process control. Their core characteristic is that the valve core (closing element) is driven by the actuator to move linearly (axially), thereby changing the flow area between the valve core and the valve seat, achieving precise and continuous regulation of fluid parameters such as flow rate and pressure.

Overpressure shut-off valve

An overpressure cut-off valve, also known as an emergency shut-off valve or safety shut-off valve, is a self-operated safety protection device that requires no external power. Its core function is to monitor the system pressure in pipelines or equipment in real time. When the pressure abnormally rises to a preset safety threshold, the valve will automatically and quickly cut off the flow path completely, thereby isolating the upstream gas or liquid source, preventing the system pressure from continuing to rise, and protecting the safety of downstream equipment, pipelines, and personnel.

Filter

Filters are key components in fluid systems used to remove impurities and purify media, and are widely used in hydraulic, pneumatic, water treatment, and fuel systems. Their core function is to protect equipment, improve system reliability, and extend component life.

pressure switch

A pressure switch is an automatic control device that triggers electrical switching based on changes in fluid pressure. It is widely used in industrial automation, hydraulic systems, air compressors, and refrigeration equipment. Its core function is to monitor pressure and output a switching signal for system protection or process control.

Explosion-proof series

An explosion-proof valve is a safety valve specifically designed for flammable and explosive environments. Its core function is to rapidly release energy when pressure abnormally increases, preventing equipment or pipelines from exploding due to overpressure. It is widely used in industries such as petrochemicals, natural gas, dust explosion hazard locations, and pharmaceuticals.
