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 Double Eccentric High-Performance Butterfly Valve is a new type of butterfly valve designed based on absorbing the advantages of several different structural butterfly valves. The sealing surface of the valve plate of this valve is a - spherical arc surface. The sealing mechanism achieves a true dynamic seal through system pressure, thus having reliable sealing performance and durability. It has a small volume, light weight, wide manufacturing range, and is easy to maintain and repair. Due to the design of the double eccentric butterfly plate, combined with a single piece of flexible lip-shaped sealing seat, it is suitable for valves in situations requiring reliable sealing and good regulating characteristics. It can be used for quick shut-off or regulating flow.
The Power Plant Check Valve has small fluid resistance, the medium channel inside the valve body is straight through, and the flow direction of the medium does not change when it flows through the check valve. The pressure self-tightening seal is used, and the two ends of the valve are usually welded. The valve flap closes quickly, the water hammer pressure is small, the body structure is simple, the production process is good, the sealing performance is good, and the sealing surface is less eroded when fully opened. A wide range of applications.
Compared with other valve products, High Temperature and High Pressure Slab Gate Valve is characterized by high temperature and high pressure. Among them, grooved flange is designed as a unique self-tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The high-temperature and high-pressure gate valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the sealing surface of the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
