The self-regulating control valve is an energy-saving control device that does not require external driving energy. It relies on the pressure or temperature of the medium being regulated as its power source, automatically adjusting according to set values based on changes in the medium. This valve integrates multiple functions of detection and control into one unit, forming an independent instrument control system. The self-operated control valve adopts a standard modular design. Our products are characterized by: standardization, serialization, and generalization. This achieves a high level of these three aspects. The components of the self-operated pressure regulator and differential pressure regulator are interchangeable. If the control conditions change, the spring & diaphragm components can be easily replaced. The accuracy of the self-operated control valve surpasses that of similar products, and it also offers high stability. Diversified product series: self-operated pressure regulator, self-operated micro-pressure regulator, self-operated temperature regulator, self-operated flow regulator, self-operated nitrogen-sealing valve, and self-operated (combined) regulator...

RAYS Blind Valve features an advanced design for quick and safe flow isolation or fluid control within pipelines. At the heart of the valve is a blind plate that can be swiftly moved in and out by turning a handwheel. To isolate the flow, simply turn the handwheel and the blind plate will slide along a track to the center of the pipe, creating a seal that blocks fluid flow. This operation does not require any special tools, nor does it involve dismantling heavy machinery or dealing with complicated bolts and nuts. The design of the blind plate ensures a stable and reliable sealing performance in any working condition, greatly simplifying the operation and reducing operational risks. The simplicity and durability of the structure also make maintenance straightforward, reducing both maintenance costs and downtime.
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
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other
