PTFE PFA steel lined PTFE pneumatic ball valve with actuator lining. The main lining materials for pneumatic ball valves are PFA/PTFE/FEP, etc. Pneumatic actuators can be selected as single acting or double acting, as well as other actuator accessories such as limit switches, air directional control valves, positioners, and air solenoid valves.
Install accessories such as limit switches, electromagnetic directional control valves, and air pressure regulating filters
actuator valve body material: stainless steel, carbon steel lining material: PFA, PTFE, etc. Size: DN40-DN400 Operation: pneumatic
PTFE lined ball valves can be divided into two-piece and three piece structural types. In addition to having low fluid resistance, fast opening and closing speed, and simple structure, ball valves with FEP lining layer have extremely high chemical stability and can be applied to any strong corrosive properties except for "molten alkali metals and elemental fluorine". Adopting a full bore and floating ball structure, the valve can be closed without leakage throughout the entire pressure range, making it easier for the pipeline system to pass through the ball and maintain the pipeline. The opening and closing ball parts are integrated with the valve stem cast (forged), eliminating the possibility of the valve stem being ejected from the pressure bearing parts due to pressure changes, fundamentally ensuring the safety of use in engineering. The structure is compact and reasonable, with the smallest internal space of the valve body, reducing medium retention. In addition, the special molding process ensures good density of the sealing surface, and the combination of herringbone ring PTFE packing enables the valve to achieve zero leakage.
