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 API 6A High Pressure Slab Gate Valve is specially designed for high-pressure pipeline systems in industries such as petroleum, natural gas, and chemical engineering. It features a valve body made of high-quality alloy steel, which is precisely machined and rigorously tested to ensure reliable performance under high pressure, high temperature, and corrosive medium conditions. The unique flat gate plate design enables two-way sealing, allowing for flexible opening and closing with low flow resistance. It is an ideal choice for long-distance pipelines, refining and chemical plants, and high-pressure fluid control systems.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate 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 the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
RAYS Three-Way and Multi-Port Ball Valve are important components in fluid control systems and are widely used in various industrial fields. They are variants of ball valves. Their design allows fluids to be distributed or converted between more than two pipes. The three-way ball valve has three interfaces, which can realize the diversion, confluence or switching of fluids. According to the different internal structures, it is divided into L-type and T-type. The L-type can only connect two mutually orthogonal pipes, and cannot simultaneously maintain the interconnection of the third pipe, and only plays a distribution role; the T-type can make three orthogonal pipes interconnected and cut off the third channel, playing a diversion and confluence role. The multi-way ball valve is an extension of the three-way ball valve, with more interfaces and more complex fluid control functions.
