An energy-saving control valve without external energy sources, used for flow control in process equipment involving non-corrosive liquids, gases, steam, etc.
Does not require any external driving energy
Has pressure balancing function and high sensitivity
Does not require maintenance, with reliable performance
Low noise, smooth operation
Adopts modular design, with high levels of standardization, seriesization and generalization
Material: WCB、CF8、CF8M
Nominal Size: DN15~250mm
Pressure Rate: PN1.6~4.0MPa
Voltage Regulating Range：0.02MPa、0.05MPa

Application range: This is applicable to automatic control systems without (or where driving energy cannot be used) in industrial processes such as water supply, petrochemicals, heating and thermal supply, energy, papermaking, food, and steel production. It is particularly suitable for automatic control system devices in natural gas extraction and transportation or gas transmission.
RAYS manufactures high-quality fully welded ball valves, forged from premium materials with side-mounted balls. The valves are available in two designs: cylindrical and spherical fully welded bodies. RAYS is particularly known for its cylindrical valve bodies.
RAYS Top Entry Cryogenic C-Type Ball Valve is a specially designed ball valve suitable for ultra-low temperature environments, especially for the control of cryogenic fluid media such as liquefied natural gas (LNG), liquid oxygen, and liquid nitrogen. The characteristic of the top entry C-Type C-Type ball valve lies in its special structural design.
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.
