1. Simple structure, high reliability: the valve disc is the only moving part, compact structure.
2. Fast closing ability: the disc stroke is short, and the closing action can be completed in a short time, effectively reducing the phenomenon of water hammer.
3. Wide range of application: suitable for a variety of media, including water, steam, gas, etc., especially in small and medium diameter pipelines.
4. Good sealing performance: metal to metal sealing pair, reliable sealing.

RAYS Side Entry Floating Ball Valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute Standard API 608&API 6D British standard BS 5351 and generally conform to American Society of Mechanical engineers standard ASME B16.34 valves are available in a complete range of body/bonnet materials and trims.
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.
RAYS Rotary Ball Valve is a special type of ball valve. In addition to the functions of a conventional ball valve, it also has good flow regulating performance and is mainly used to control the flow of media in pipelines. Flow regulating ball valves are usually composed of a valve body, a ball, a valve seat, a valve stem and an actuator. Its working principle is to change the size of the valve channel by rotating the ball, thereby adjusting the flow of the fluid. When the ball rotates to different positions, the opening of the valve channel will change, thereby controlling the flow of the fluid.
