The main components are forged. Forged steel gate valves have three types of middle cavity seals: bolted bonnet, welded bonnet, and middle cavity pressure self-tightening seal structure.
A bolted bonnet means that the valve body and bonnet are connected with bolts and nuts and sealed with a wound gasket (made of stainless steel wire clips and flexible graphite). Metal ring connection can also be used when customers have special requirements.
Welded bonnet means that the valve body and bonnet are connected with threads and fully welded. The fully welded connection can also be used when customers have special requirements.
The middle cavity of 900Ib, 15001b, and 25001b adopts a pressure self-tightening seal structure. The sealing performance increases with the increase of internal pressure and has high reliability.
The channel is smooth, and the flow coefficient is small. The sealing surface is less eroded and eroded by the medium.
The sealing surface is made of alloy steel or hard alloy, which has good wear resistance and abrasion resistance.
Flexible graphite filler is used, the sealing is reliable, and the operation is light and flexible.
The flow direction of the medium is not restricted; there is no disturbance, and the pressure is not reduced.
The packing replacement and maintenance can be carried out in the state of online shutdown, which is convenient and fast without affecting
the operation of the system.
The shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide.

Three eccentric butterfly valve series is the newly-developed long-life and energy-saving products. The sealing is metal to metal, which couldbe changed to be seal ring to metal, stainless steel plate and composite graphite to metal. Under the working condition of high temperature and high pressure, it still has a stable sealing performance. Our company adopts optimization design and new technology, so that the torque is small, gainning the point of energy-saving, labor-saving and reliable sealing performance, thus to ensure the high-reliability of corrosion-resistantance, stand fire and wear-resistantance. This product is widely used in petroleum, natural gas, piped gas and medicine, food industry, industrial environmental water treatment and shipping industry.

RAYS Three-Way and Multi-Way Ball Valves 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.
