As a key component in industrial automation control systems, regulating valves are used to precisely control the flow rate, pressure, temperature, and other parameters of fluids (gases, liquids, etc.) to meet the needs of different operating conditions. Our company focuses on the research and production of high-performance regulating valves, with products including electromagnetic normally open valves, proportional flow valves, high and low temperature explosion-proof servo regulating valves, and other series. These valves have the characteristics of high precision, high reliability, and long service life, and are widely used in the fields of petrochemicals, power energy, aviation, and aerospace.

Electromagnetic normally open valve is a basic type of electromagnetic control valve, which is in the open state by default and only closes when powered on. It is suitable for safety critical systems that require power-off to ensure continuity, such as fire protection, gas or emergency pressure relief devices. The valve structure is simple, usually using brass, stainless steel or engineering plastic valve body, and the internal sealing material is mostly wear-resistant nitrile rubber or fluororubber, ensuring long-term use without leakage.

Product Highlights and Advantages:

Safety redundancy design: automatically reset to the open state when power is cut off, avoiding system pressure buildup, suitable for scenarios such as fire protection and emergency gas cut-off

Quick response: Action time is usually less than 50ms, suitable for high-frequency switching situations

Low power consumption: energy-saving coil design, power consumption can be as low as 2W, supporting DC12V/24V or AC220V power supply

Wide compatibility: CE and RoHS certified, compatible with corrosive media (such as optional PTFE sealing)

Proportional flow valve is a high-precision flow control device that achieves linear or nonlinear control of flow through electrical signals (such as 0-10V or 4-20mA). It is widely used in hydraulic systems, injection molding machines, chemical process control and other applications that require dynamic flow matching. The valve is driven by a proportional electromagnet or servo motor, and the valve core is designed as a precision slide valve or nozzle baffle structure to ensure that the flow rate strictly corresponds to the input signal.

Highlights and advantages:

High precision adjustment: repeatability accuracy ± 0.5% FS, resolution up to 0.1% FS, suitable for hydraulic servo systems or precision injection molding machines

Fast dynamic response: The frequency response can reach over 10Hz, adapting to rapidly changing working conditions

Energy saving and consumption reducing: dynamically matching flow demand through PID algorithm, reducing overflow losses, and saving more than 30% energy

Multi functional integration: Some models come with temperature compensation function to avoid changes in oil viscosity affecting control accuracy

Explosion proof servo regulating valve is a type of regulating valve with an upward guiding structure. The fluid channel of the valve body presents an S-shaped flow direction, with small pressure drop loss, relatively large flow rate, wide adjustable range, high accuracy of flow characteristic curve, large upward guiding area, and obvious seismic advantages. Its core highlights include strong environmental adaptability (tested through salt spray, vibration, and thermal shock), intelligent adaptive control (automatically compensating for changes in medium characteristics or mechanical wear), and highly customizable capabilities (such as ultra-high pressure 1000Bar or vacuum specific versions), making it an ideal choice for high-end industrial control fields.

Highlights and advantages:

Reliability under all operating conditions: verified through salt spray test (1000h), vibration test (5-2000Hz), and thermal shock test

Intelligent diagnosis: supports MODBUS/PROFIBUS communication, real-time monitoring of valve position, temperature, and vibration data, predicting faults

Adaptive control: Built in AI algorithm, automatically compensates for changes in medium viscosity or actuator wear, extending lifespan

Customized service: We can provide ultra-high pressure (above 1000Bar) or vacuum specific versions according to working conditions
