This regulating valve adopts a pressure-balancing type valve core design, significantly reducing the operating torque. Combined with a high-precision guiding system, it achieves a regulation accuracy within 0.5%. The unique low-temperature compensation structure effectively counteracts the material shrinkage effect, ensuring stable performance across the entire temperature range. The valve internals are treated with a special surface treatment process, increasing the wear resistance by more than three times.

The dual plate check valve features two semicircular, spring-loaded valve discs mounted on a central vertical pivot. When the valve opens, the force of the fluid and the spring act at the center of the disc, causing it to open from the base first. This design minimizes wear on the seal during opening, enhancing its durability. As the flow decreases, the discs slowly move back towards the seat due to the spring's force, ensuring a gradual closure. During backflow, the increased force on the discs leads to a faster closure, effectively reducing the risk of water hammer and hydraulic shocks. The spring’s force closes the top end of the disc first, preventing damage at the disc's base and prolonging the seal's lifespan.
The Rotary Ball Valve adopts advanced ball rotation sealing technology and is specially designed for harsh working conditions. It is suitable for the control of high-pressure, high-temperature and corrosive media in industries such as petroleum, chemical engineering, natural gas, and power. Its unique rotating valve seat structure effectively reduces friction and wear, ensuring more durable sealing performance and easier operation. The valve body is made of high-quality stainless steel, carbon steel or special alloy materials, and is precisely processed and hardened to ensure long-term stable operation. It supports various driving methods such as manual, pneumatic, and electric, meeting different automation requirements and is an ideal choice for industrial pipeline fluid control.
Our company has developed a variety of series of Angle control valves. They feature a compact valve body structure, low pressure drop loss, large flow rate, unobstructed flow channel with low resistance within the adjustable range, and high accuracy of the flow curve. It is particularly suitable for regulating high-viscosity fluids containing suspended solids and granular materials, which can prevent coking, adhesion, clogging and other phenomena, and is convenient for self-cleaning and cleaning. The control valve is equipped with the RSMF type multi-spring pneumatic diaphragm actuator, which features a simple and firm structure, large output force and long service life.
