Overview:
Air is a kind of v-type regulating ball valve core seat using metal, or metal for ptfe seal with the rotation of the ball valve, it is the best ball valve and butterfly valve control features combined into an organic whole, not only can be used as a control valve, cut-off valve and can make off. Its main features are:
(1) with no coupling integral body, so is not affected by pipeline or bolt stress, and because the body without any pipe joint, so the pressure hull would not be affected by pressure "mutation";
(2) with a v-shaped body, even if in the case of small flow rate or high viscosity media, can also be within the scope of the whole range, ensure the control accuracy;
(3) the leakproof durable seat at the outer diameter of PTFE lined with stainless steel inner core cup or type O sealing ring, the seat made from cross section larger cobalt tungsten carbide, by a corrugated alloy spring to further enhance the structure of the seat;
(4) when the valve is closed, v-shaped gap between wedge and seat shearing action, and both have the function of self-cleaning and can prevent the ball core is stuck, especially suitable for the pipeline scaling or containing fibers and particles frozen solid.
Suitable for high viscosity, slurry, pulp is not clean, fiber media such occasion. Adopt direct way to connect with the actuator, with compact structure, small size, light weight, small resistance, the advantages of stable and reliable. Actuators according to user requirements configuration UNIC, PSQ, HQ, DHL and other types of electronic electric actuators or GTX, AL pneumatic piston type actuators, etc.
