As a leading ball valve manufacturer RAYS FLOW CONTROL has been producing industrial ball valves to the highest quality standards with ultra-modern manufacturing technology and astute materials sourcing.
C700 Single Seated Control Valves are a top-guided single-seat valve. This series of products has absorbed the advantages of similar products at home and abroad and has been improved and innovated. In terms of design, process, and assembly, it has reached the advanced level of similar products domestically and internationally. It has a compact structure, small volume, smooth flow channel, and the fluid passage is in an S-shaped streamline. The flow characteristic curve has high precision, is stable and reliable, and is easy to maintain.
The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
Special type control valves are customized valve products designed by our company for complex working conditions (such as high temperature, high pressure, strong corrosion, high precision, and low-temperature control, etc.). They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes. Ultra-low temperature regulating valve: CUT701 Cryogenic temperature control valve is a top-guided structure that is designed for use at ultra-low temperatures (-196℃). All components of the valve have undergone special design and low-temperature process treatment, which can meet the usage requirements of various special working conditions. The core parts can be replaced online. Its structure is compact and the design is reasonable. The long-necked valve cover with insulation can make the valve stem sealing area work close to normal temperature. Reduce the transfer of external heat to ensure the reliable operation of the valve under ultra-low temperature conditions.
Our company has developed a variety of series of Angle control valves. They feature a compact valve body structure, low pressure drop loss, large flow rate, unobstructed flow channel with low resistance within the adjustable range, and high accuracy of the flow curve. It is particularly suitable for regulating high-viscosity fluids containing suspended solids and granular materials, which can prevent coking, adhesion, clogging and other phenomena, and is convenient for self-cleaning and cleaning. The control valve is equipped with the RSMF type multi-spring pneumatic diaphragm actuator, which features a simple and firm structure, large output force and long service life. *CAV701-V Venturi Angle valve *CAV701 Angle single-seat control valve *CAV702 Angle caged globe control valve *CAVL702 Angle low-leakage caged globe control valve *CAVH701Angle high-pressure single-seat control valve *CAVH702 Angle high-pressure caged globe control valve *CAVHW701 Bellows Seal Angle High-pressure single-seat valve
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

They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes. Ultra-low temperature regulating valve:
The CH700 High Pressure Control Valve is a high-precision fluid control device specially designed for harsh industrial environments. It is suitable for high-pressure pipeline systems in industries such as petroleum, chemical engineering, power, and metallurgy. This product uses high-quality materials and advanced manufacturing techniques to ensure stable operation even under extreme conditions such as high pressure, high temperature, and strong corrosion. Its compact structure and reliable sealing enable precise regulation of flow and pressure, meeting the strict requirements of complex industrial processes. The high-pressure regulating valve has excellent shock resistance and vibration resistance, and is suitable for frequent opening and closing and high-load operation environments. It is also easy to maintain, effectively reducing long-term usage costs, making it an ideal choice in the field of industrial fluid control.
The CN700 Low-Noise Control Valve is divided into the CN702 and CDN702 series, mainly designed to reduce the noise of compressible fluids. To adapt to the throttling, diffusion and expansion of gases, the valve core adopts a pressure-balanced structure, and the sleeve is equipped with many symmetrical small holes to reduce pressure drop. The fluid passage is in an S-shaped streamline, and a deflector wing is also provided to improve the smooth flow of the fluid around the sleeve. Therefore, the control valve has low pressure drop loss, large flow rate, low noise and less cavitation corrosion. The control valve is equipped with the RSMF series multi-spring pneumatic diaphragm actuator, which has a simple and compact structure, stronger stability, large output force and long service life.
