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.
Stop Check Valve, A multi-purpose valve that functions as both a stop valve and a check valve. Its structure is similar to that of a globe valve, but the stem and disc are not fixed. When the stem is lowered and the disc is pressed tightly on the seat, it acts as a stop valve; After the stem rises, the check valve acts. On lines that require both a stop valve (or gate valve) and a check valve (such as the outlet of a water pump), using a stop check valve can save installation costs and space. In the opening and closing process, because the friction between the valve disc and the sealing surface of the valve body is smaller than that of the gate valve, it is more wear-resistant.
Oxygen Service Globe Valve are often used in physical and chemical experiments with gases such as oxygen, nitrogen, hydrogen, argon, etc. These gases are usually stored in dedicated high-pressure gases. When in use, the gas pressure is reduced to the required range for the experiment through a pressure reducing valve, and then finely adjusted through other control valves to input the gas into the system. The oxygen shut-off valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak.
