CLW702 Low-leakage Bellows-sealed Cage-guided Control Valve
The CLW702 Low-leakage Bellows-sealed Cage-guided Control Valve is a pressure-balancing type control valve. The valve core adopts a pressure-balancing structure and uses a smaller actuator force to control the high-pressure difference. There is a sealing ring between the valve core and the valve cage, which reduces the leakage. The upper valve cover adopts a bellows-sealed structure, which can completely eliminate the possibility of medium leakage from the valve stem movement gap. Therefore, it is widely used in automatic control systems for highly toxic, highly corrosive, radioactive, and rare and valuable media. The fluid passage of the valve body is in an S-flow pattern. Its advantages are small pressure drop loss, large allowable flow capacity, large adjustable ratio, and high flow characteristic accuracy.
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 core feature is to utilize the bellows as the dynamic sealing element, replacing the traditional packing seal.
● It adopts a leak-free design. The bellows completely isolates the valve stem from the medium, effectively preventing the medium from leaking out through the outer surface of the valve stem.
● It has strong pressure resistance. The metal bellows can withstand high pressure and has stable sealing performance.
● There is no friction from packing materials, and the movement resistance of the valve stem is small, improving the adjustment accuracy and response speed.
● It avoids the valve stem getting stuck due to particles invading or hardening as in the traditional packing seal, reducing the risk of jamming.

The globe valve is mainly composed of valve body, valve cover, valve disc, valve stem and valve stem nut. The handwheel applies a certain torque on the upper end of the valve stem, and passes the valve stem to the valve petals to move it along the valve stem axis to achieve full or full-closed motion. The force applied by the handwheel can be obsessed with the valve seat to reach the stagnation state. The two-valve petals are designed to enter the top of the medium from the cover of the valve petals. The force force of the medium is the same as the valve closure direction, so the torque of the valve closure is small; The petals, the medium enters the exit of the valve from the inside, and generates a small amount of balance of the pressure of the pressure on both ends of the valve inlet and export, thereby achieving the effect of reduced the valve opening torque. Therefore, globe valve(double disc) is mainly used in high pressure or large-caliber pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
RAYS single driving double ball valve is a special ball valve design, which combines two ball valves together, but is operated by only one drive device. This design is usually used in situations where two parallel pipelines need to be controlled or isolated at the same time. The design and application of single drive double ball valves need to consider specific process requirements and operating conditions to ensure its long-term stable operation and system safety.
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.
