● The length of the structure is short series, the valve is light in weight, and the pipe support frame can be saved.
● The valve in the process of opening and closing the gate can scrape off the attached medium by itself, which is conducive to sealing.
● Knife gate is conducive to cutting off the medium, slagging, valve operation unblocked.
● Valve adopts clamp connection. Wedge limit provides sealing force and reliable sealing.
● Wear-resistant bushings of different materials can be provided according to requirements to extend the service life of the valve.
● Drive device (electric, gearbox, pneumatic, hydraulic) can be optional.

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 mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
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 Throttle Stop Valve is mainly composed of valve body, valve cover, valve flap, and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals to move it up and down along the valve stem axis to realize the full-opening, full-closed movements and regulating traffic functions. The force applied by the hand wheel can be obsessed with the valve seat to reach the sealing state; Location, change the cross-sectional area between the valve petals and the cover of the valve seat, and achieve the purpose of regulating media flow. At the same time, the throttle stop valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the life of the valve.
