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.

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.
The valve disc of the Cryogenic Lifting Check Valve adopts a vertical lifting structure and is equipped with a cobalt-based alloy sealing surface. It can achieve rapid response and reliable sealing when the medium pressure changes. The product complies with BS 6364 and API 6D standards and is suitable for the transportation systems of low-temperature media such as LNG and liquid oxygen. The working pressure can reach Class 2500 and meets the strict working conditions requirements in the petrochemical and air separation fields.
The Sampling Double Disc Gate Valve is an efficient valve specifically designed for industrial sampling. It features a double-gate structure that ensures reliable sealing and precise sampling control. The unique double-gate design guarantees stable media flow during the sampling process while effectively preventing leakage and contamination. This valve is widely used in industries such as chemical and pharmaceutical, especially for sampling inspections in reactors under crystallization conditions.
