Control Valve Series

A control valve is a mechanical device used to regulate the flow, pressure, temperature, or liquid level of a fluid by automatically adjusting the position of its internal components in response to signals from a control system, playing a crucial role in maintaining process stability and efficiency across various industrial applications such as chemical plants, power generation, and oil refineries.

Power Station Regulating Valve

The regulating valve is composed of two parts: an electric actuator and a steam trap regulating valve. With its excellent performance and innovative design, it has become an ideal choice in the field of fluid regulation for power stations.

ZAZP Electric Control Valve

The ZAZP type electric control valve is ingeniously composed of an electric actuator and various types of valve bodies (single-seat, double-seat, and sleeve), thus possessing the unique characteristics of different control valves.

Nitrogen Seal Valve

The ZZYVP type control valve is mainly suitable for specific occasions where the pressure in front of the valve is relatively high (ranging from 0.2 to 0.8 Mpa), while the pressure behind the valve is extremely low (ranging from 0.5 to 100 Kpa, such as a pressure as low as 50 mmH₂O).

T40 Manual Control Valve

The T40 manual regulating valve is applicable to steam and hot water pipelines with a nominal pressure of ≤1.6MPa or ≤2.5MPa and a medium temperature of t≤200℃ or ≤350℃, primarily serving the purpose of flow regulation. As an energy-efficient product, it is especially suitable for urban central heating or district heating systems, excelling in achieving precise flow control.

ZJHM Pneumatic Diaphragm Control Valve

The ZJHM compact pneumatic diaphragm cage control valve represents an upgraded version of the previous-generation ZMAM model. This product stands out with its excellent stability, wide-ranging applicability, and user-friendly maintenance features. Thanks to its small orifice throttling design, it can significantly reduce operational noise.

ZDLM Cage Type Control Valve

The ZDLM cage type control valve is composed of an intelligent integrated actuator and a single-seated control valve. Its suitable for working scenarios where extremely strict control over leakage is required, the pressure difference before and after the valve is relatively small, and the conveyed medium has a certain viscosity or contains fibrous substances. It can operate stably and reliably.

Pneumatic three-way control valve

The pneumatic three-way control valve boasts remarkable advantages such as an ingeniously simple structure, light weight, compact size, and convenient disassembly and assembly. It is widely applied to the control of various process parameters (such as pressure, flow rate, temperature, liquid level, etc.) of media like gases and liquids.

ZJHP Pneumatic Control Valve

The ZJHP pneumatic control valve adopts a sophisticated top-guided structural design and is equipped with a multi-spring actuator. It has many remarkable advantages, such as a compact and reasonable structure, light weight, sensitive and quick response in operation.

Thermostatic Control Valve

The thermostatic control valve has the ability to precisely regulate various parameters such as pressure, flow rate, liquid level, temperature, and humidity. It is widely applied in the production processes of many industries, including air conditioning and refrigeration, heating, heat supply, chemical engineering, petroleum, metallurgy, and power.
