The valve disc of the Cryogenic Swing Check Valve adopts a cantilevered swing structure, combined with precisely machined valve seat sealing surfaces, to achieve rapid response and reliable sealing, effectively preventing the reverse flow of the medium. The overall design of the valve complies with international standards such as BS 6364 and ISO 28921, and is suitable for low-temperature conditions in air separation plants, liquefied natural gas storage and transportation, and the chemical industry.
The Sampling Double Disc Gate Valve is an efficient valve specifically designed for industrial sampling. It features a double-gate structure that ensures reliable sealing and precise sampling control. The unique double-gate design guarantees stable media flow during the sampling process while effectively preventing leakage and contamination. This valve is widely used in industries such as chemical and pharmaceutical, especially for sampling inspections in reactors under crystallization conditions.
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
