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:
● Adopting elongated valve cover to prevent cold conduction and freezing of packing, thereby eliminating the adverse impact of ultra-low temperature on the sealing performance of the stuffing box;
● Main components undergo hardening treatment, ultra-low temperature treatment, and ultra-precision processing to ensure precise regulation of flow and pressure.
● Passed strict ultra-low temperature deep cryogenic tests to guarantee stable operation under extreme conditions, ensuring safety and reliability.

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.
The Lifting Plug Valve adopts a unique dual-action design of lifting and rotation. When opening, it first lifts and then rotates to achieve zero-friction operation. It is particularly suitable for high-pressure difference, easily crystallizing and media containing solid particles. The valve body and the plug are both precisely ground, and the self-cleaning sealing surface design ensures reliable sealing performance under harsh conditions. It is widely used in high-parameter working conditions in the petroleum, chemical and power industries.
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.
