HTHP Slab Gate Valve has small fluid resistance, and the internal medium channel of the valve body is directly connected. The medium does not change its flow direction when the gate flows through the gate valve. The pressure self-tightening seal is adopted, and the two ends of the valve body branch pipe are usually welded. The torque required for opening and closing is small, the body structure is simple, the manufacturing process is better, the sealing performance is good, and the corrosion of the dense cover when the full opening is less. The scope of application is wide. The phenomenon of water hammer is not easy to produce due to the long closing time. The medium can flow to either side in any direction, easy to install.

Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering
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.
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.
