• Self-balanced pressure design on the upper and lower sides of the valve plug enables tight shutoff with low actuator thrust, making it suitable for large-size and high-pressure applications.
• The valve body adopts a straight-through streamlined internal flow path, reducing flow resistance and achieving a higher Cv value.
• Sensitive operation, high-precision positioning, fast response, robust structure, long service life, compact design, and small installation footprint.

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 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.
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.
