The Self-operated Pressure Regulating Valve is a reliable and cost-effective solution for precise pressure control in pipelines without the need for external power sources. Utilizing the energy of the process fluid, it automatically adjusts to maintain set pressure levels, making it ideal for applications in steam systems, gas distribution, and liquid process lines. Its simple design ensures low maintenance and long-term reliability in demanding industrial environments.

The Self-operated Micro-Pressure Regulating Valve is a precision-engineered solution designed for ultra-fine pressure control in low-pressure systems. Utilizing the energy of the process fluid, it automatically adjusts to maintain set pressure levels with exceptional accuracy, making it ideal for applications in laboratory equipment, gas analyzers, and precision instrumentation. Its compact design and self-operating mechanism ensure reliable performance without the need for external power sources.

The Self‑operated Temperature Regulating Valve is an automatic control valve that requires no external power source (electricity or compressed air). It opens and closes solely by the temperature change of the controlled medium. Its core component is a temperature sensor bulb (thermostatic bulb) and an actuating bellows.

The Pneumatic Single Seat Control Valve is a high-performance regulating valve designed for precise control of fluid pressure, flow rate, or temperature. Driven by a pneumatic actuator and featuring a single-seat plug structure, it offers compact design, rapid response, and exceptional reliability in demanding industrial environments such as oil and gas, chemical processing, and power generation, especially in explosion-proof applications.

The Pneumatic Three‑Way Control Valve is a pneumatic control valve with three ports (one inlet/two outlets or two inlets/one outlet), designed for mixing (combining two inlet flows into one outlet) or diverting (splitting one inlet flow into two outlets) applications. Driven by a pneumatic diaphragm actuator, it receives a standard pneumatic signal (0.02–0.1 MPa) or a 4–20 mA electrical signal via an I/P converter, and changes the plug position to proportionally distribute flow among the ports.

The Pneumatic Angle Control Valve is a high-performance flow control solution designed for precise regulation of fluids in high-pressure drop and erosive applications. Featuring a compact angle body design and a diaphragm-style pneumatic actuator, it ensures reliable operation in demanding environments such as steam systems, power plants, and chemical processing units. Its unique geometry minimizes turbulence and erosion, making it ideal for applications with high ΔP and particulate-laden media.

The Electric Sleeve Regulating Valve is a robust, high-precision solution for critical flow control in extreme industrial environments. Its sleeve-guided trim, smart electric actuation, and heavy-duty materials ensure reliable performance in oil & gas, power generation, and chemical systems. By combining advanced engineering with adaptive control, this valve delivers unmatched stability and efficiency under the most demanding conditions.

The Electronic Single-seat Control Valve is a precision flow control device designed for applications requiring accurate regulation of pressure, temperature, or flow rate in liquid, gas, and steam systems. Featuring a single-seat globe valve design and electronic actuator, it combines high shut-off capability with advanced digital control, making it ideal for chemical processing, HVAC, and industrial automation.

The Electric Three‑Way Control Valve is an electric control valve with three ports (one inlet/two outlets or two inlets/one outlet), designed for mixing (combining two inlet flows into one outlet) or diverting (splitting one inlet flow into two outlets) applications. It is driven by a linear‑stroke electric actuator and receives a standard analog control signal (4–20 mA or 0–10 V DC). The motor moves the plug linearly to proportionally distribute flow among the ports.
