The gate valve has a small fluid resistance, and the internal medium channel of the valve body is directly connected. The medium does not change
its flow direction when flowing through the gate valve. 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
applications is wide. Because the phenomenon of the long water hammer is not easy to occur. The medium can flow in any direction on both sides
and easy to install.
Application Scenario: The non-rising stem gate valve is generally used in strict requirements on the height of the valve, but the use conditions are more harsh. For example, a high -temperature and high pressure working medium, toxic and harmful risk liquids require closure to ensure long-term
sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. Such as the application of power industry, petroleum
refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry and other fields.

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.
The Cryogenic Single-seat Control Valve is specially designed for low-temperature working conditions ranging from -196℃ to +80℃. It features an integral forged valve body structure and is equipped with a bellows seal assembly to ensure reliable sealing under extreme temperature conditions. The valve core is designed with a parabolic or equal percentage flow characteristic, forming a precise fit with the hardened alloy valve seat to achieve precise control of the medium flow. The product complies with IEC 60534-4 and GB/T 4213 standards, and is suitable for precise regulation of low-temperature media such as LNG, liquid oxygen, and liquid nitrogen. The pressure rating covers ANSI Class 150 to 900, and is widely used in key areas such as air separation equipment and low-temperature storage and transportation systems.
The cryogenic butterfly body can be provided in twostructural forms, namely flange connection and butt.welding connection (both with inspection ports). The body with inspection ports can replace the valveinternals online, making maintenance work extremelysimple, which is conducive to the rational use ofresourcesand saving maintenance costs.The extended valve cover + drip tray design ensures thatthe temperature at the stuffing box is above zero degrees!so that the connection between the stuffing and the stemwill not freeze and lock.
