During the opening and closing process, the friction between the valve petals and the cover surface is small and wear-resistant. The itinerary height
is relatively small. The action is sensitive and the sealing performance is good; The overall structure, simple and compact, beautiful shape. Long
service life and high reliability.
Application Scenario: The deeper valve is generally used on the pipelines that are not strict with the flow resistance on the pipeline, that is, the place where the pressure loss is not large. For example, a high-temperature and high pressure working medium, toxic and harmful risk liquids require
closure to ensure long-term sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. Such as the
application of power industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry
and other fields.

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.
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 Cryogenic High-Performance Butterfly Valve adopts an offset valve stem and eccentric butterfly plate design. When opening and in the middle position, the valve seat and the butterfly plate do not contact each other, which reduces the friction on the valve seat while reducing the torque, and improves the durability of the valve. It is a high-performance regulating and cutting valve. The valve is designed to handle various media that are most difficult to handle in today's industrial environment, including liquid oxygen, liquid natural gas and other cryogenic liquids.
