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.

超低溫蝶閥采用偏置閥桿和偏心蝶板設(shè)計，在開啟和處于中間位置時，閥座與蝶板不發(fā)生接觸，在減小扭矩的同時減少了對閥座的摩擦，提高了閥的耐久性，是一種高性能的調(diào)節(jié)、切斷型閥門。該閥門的設(shè)計旨在應(yīng)對當今工業(yè)環(huán)境中最難以處理的各種介質(zhì)，包括液氧、液態(tài)天然氣和其他低溫液體。

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.
