Metal seat Butterfly Valve

Product Details

Metal Seated Valve Spheres

     The metal seated valve spheres are mainly assembled in metal seated ball valves, including the PMSS (primary metal and secondary soft seal) and metal to metal ball valves. It’s an upgraded process of soft/ resilient seated valve spheres.

    When the soft/ resilient seated valve spheres are completed, go through some kind of surface treatment, such as ENP, hard chrome, Ni55, Ni60, stellite, HVOF/ HVAF TCC, nitriding, etc., to achieve the specific function(s), such as hardness, roundness, roughness, etc. A very import point, is grinding, the balls must be match lapping with two metal seats, to relaize the zero leakage after assembled in ball valves. So this kind of spheres are always ordered with seats. Besides, the inserted soft seats (PTFE, R-PTFE, DEVLON, PEEK, Nylon, etc.) can also be furnished along with metal seats and balls against requirements, to save the time of our customers.
