This series of products features a compact structure, small size, and S-shaped fluid channels. The valve core adopts a pressure-balancing structure, with high accuracy of the flow characteristic curve and the ability to achieve a larger CV. It can be quickly replaced, is stable and reliable, and is easy to maintain. A smaller actuating force can control a high pressure difference. There is a sealing ring between the valve core and the valve cage, significantly reducing the leakage. It is equipped with the RSMF series multi-spring pneumatic diaphragm actuator, which has a large thrust, strong steel strength, sensitive action, high-precision positioning, fast response, convenient and sturdy, and a long service life.
An energy-saving control valve without external energy supply, used for non-corrosive liquids and gases with a temperature of ≤ 200℃ for differential pressure control devices. The valve opens or closes when the differential pressure increases.
The valve body is made of high-strength alloy steel or stainless steel, and is equipped with a precisely processed swing-type valve disc structure, enabling automatic control of the unidirectional flow of the medium. The optimized fluid dynamics design effectively reduces water hammer impact. The surface of the valve disc is clad with hard alloy to ensure reliable sealing under high-pressure and high-speed conditions. It is suitable for pipeline systems in industries such as petroleum, chemical engineering, and power.
