CW700 Series Bellows Seal Control Valves are divided into three major series: CSW701/CW701/CW702/CLW702 type bellows-sealed single-seat regulating valves and bellows-sealed cage-type regulating valves, as well as low-leakage bellows-sealed cage-type regulating valves. The bellows-sealed single-seat regulating valve is a regulating valve with top guide structure. The bellows-sealed cage-type regulating valve is a regulating valve with pressure balance. The valve body has an S-flow channel type passage, with small pressure drop loss, large flow rate, wide adjustable range and high flow characteristic accuracy. The low-leakage bellows-sealed cage-type regulating valve not only has the advantages of cage-type regulating valves, but also has a sealing ring between the valve core and the valve cage, reducing the leakage. The full series of upper valve covers adopt bellows-sealed structure, which can completely eliminate the possibility of medium leakage from the valve stem movement gap to the outside. When equipped with the RSMF series actuators, it has a compact structure, large output force and long service life. Therefore, it is widely used in automatic control systems of highly toxic, strongly corrosive, radioactive and rare and precious media. *CSW701Bellows Seal small-Port single-seat control valve *CW701 Bellows Seal single-seat control valve *CW702 Bellows Seal caged globe control valve *CLW702 Bellows Seal Low-leakage bellows caged globe control valve
The slow-closing check valve opens and closes the valve disc automatically due to the flow of the medium, and is a type of automatic valve used to prevent the backflow of the medium. It is mainly used to prevent backflow of the medium, prevent the reverse rotation of pumps and drive electric motors, and release the medium in containers. The check valve can also be used in pipelines that supply supplementary pressure to auxiliary systems where the pressure may rise above the system pressure.
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.
