Swing Double Disc Check Valve Specifications: The swing flex check  is designed to be maintenance-free and has superior performance compared with traditional swing check valves. The disc is the only moving part of the valve, and it can be easily replaced without removing the valve from the pipeline. Its unrestricted full flow design makes swing flex check an excellent choice for slurries and sludges, even in vertical upward flow applications. The non-impact performance is ensured by placing the valve seat at a 45° angle, thereby minimizing the disc stroke. When used with the optional rubber lining, our swing flex check is ideal for high-wear and corrosive applications. Independent process, cycle and performance test report certification can be provided upon request. The cover-mounted Disc Position Indicator clearly indicates the valve's disc position. A proximity limit switch can also be provided to indicate open/closed position to a remote location.A Backflow Actuator is available...

According to the sealing surface configuration, it can be divided into wedge gate valve and parallel gate valve. Wedge gate valve can be divided into: single gate, double gate and elastic gate; parallel gate valve can be divided into single gate Plate type and double gate type. Divided according to the thread position of the valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve. 【 Resilient Seat Gate Valve 】 For industrial valves, the opening and closing parts of soft-sealed gate valves are gates. The movement direction of the gates is perpendicular to the direction of the fluid. The gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. [Principle of Resilient Seat] The resilient seat l gate valve is divided into two types: bright-stem resilient seat gate valve and dark-stem resilient seat gate valve. Usually there is a trapezoidal thread on the lifting rod, through the nut in the middle of the gate and the gui...

The sealing surface material of the valve seat is different. 1.  Resilient Seat : in the use of resilient seat, the two contacting sealing surfaces can be separate or all soft materials such as plastic and rubber can be used. Since the soft material is easy to deform and fills up the unevenness of the sealing surface, the soft seal can achieve a very high degree of medium sealing performance, and this extremely high degree of medium sealing performance can be repeatedly achieved. The disadvantage is that the use of soft sealing materials is affected by the pressure and temperature that the sealing materials can withstand. 2.  Metal Seat : metal seat is generally made of metal, so it is also called metal sealing surface. The metal sealing surface is susceptible to deformation due to the influence of the medium and the sandwiched particles; it is further damaged by corrosion, erosion and wear. On the contrary, if the wear particles are less uneven than the surface, the accuracy ...
