The Single Disc Check Valve adopts a low-inertia design, featuring fast response and adjustable closing time. The contact surface between the valve disc and the valve seat is specially hardened, ensuring excellent wear resistance. A spring-assisted closing option is provided to prevent backflow of the medium. The overall structure is compact, and the installation orientation is not restricted. The working pressure can reach Class 2500, with a temperature range of -196℃ to 550℃. It meets the requirements of international standards such as API 6D.
Material: Carbon steel, stainless steel, alloy steel, etc
Nominal Size: NPS2~NPS12/DN50~DN300
Pressure Rate: Class150~ Class 2500/PN20~PN420
Temperature Range: -29℃~540℃
Operator: Manual, Pneumatic, Electric, etc
Application range: The check valve is generally used in the pipeline where the convection resistance requirement is not strict, that is, where the pressure loss is not considered. Such as high temperature and high pressure working media, toxic and harmful dangerous liquids, the closing parts are required to ensure long-term sealing and no leakage. In general, the conditions of use require reliable sealing performance. Such as power industry, petroleum refining, petrochemical, offshore oil, urban construction of water engineering, chemical industry and other fields of application.

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.
RAYS Blind Valve features an advanced design for quick and safe flow isolation or fluid control within pipelines. At the heart of the valve is a blind plate that can be swiftly moved in and out by turning a handwheel. To isolate the flow, simply turn the handwheel and the blind plate will slide along a track to the center of the pipe, creating a seal that blocks fluid flow. This operation does not require any special tools, nor does it involve dismantling heavy machinery or dealing with complicated bolts and nuts. The design of the blind plate ensures a stable and reliable sealing performance in any working condition, greatly simplifying the operation and reducing operational risks. The simplicity and durability of the structure also make maintenance straightforward, reducing both maintenance costs and downtime.
Sleeve plug valve is a kind of precise fluid control equipment, its clever design lies in the sleeve connection between the plug and the valve body. This structure not only ensures excellent sealing performance in high-pressure environments, but also facilitates installation and maintenance. Sleeve plug valve for its reliable cut-off capacity and smooth media flow characteristics. It is mainly used for oil and gas storage and transportation in chemical industry, metallurgy, paper making, food processing and other industries, for opening or closing, and with pneumatic and electrical devices can also achieve remote operation to ensure personal safety.
