56 Inch Ball Valve
Description of 56 Inch Ball Valve:
The largest size ball valve produced by ZECO is 56 inch, and it has its own mold, which can catch up with users’ urgent needs with the fastest delivery speed and the highest quality price and meet users’ requirements for cost control. ZECO has been producing ball valves in China for nearly 30 years and has 3 production bases in China, has high-precision CNC machine tools & machining centers, advanced equipment and inspection instruments, fine techniques and strict & perfect quality management system. Moreover, we gather professional elites to form a team of advanced scientists & technologists so as to make full use of new technologies, new techniques, and new materials in order to guarantee stability and reliability of products. Product quality originates from advanced manufacturing means, and fine product concepts stem from continuous innovation.
Features of 56 Inch Ball Valve:
1. ZECO 56 inch ball valve has anti blow-out stem. Because the valve diameter is too large, when replacing the packing, if there is no stem anti blow-out structure, the personnel cannot control the position of the stem at all, the stem will be pushed out of the valve body due to the huge pressure caused by the pipeline site specific property losses and personnel safety threats;
2. ZECO 56 inch ball valve is designed with super fire safe structure to prevent great loss after fire. After the resilient seal structure is damaged by fire, if there is no fire safe structure, it will cause huge leakage, and after the fire safe structure, the metal seal structure will replace the resilient seal structure to keep close cooperation with the ball, so as to prevent leakage and cause greater losses;
3. ZECO 56 inch ball valve has excellent design in o-ring and gasket combination to prevent leakage from body connection area;
4. ZECO 56 inch ball valve has floating spring-loaded seats design to assure sealing even at low pressures.
