Steel lined PTFE pneumatic ball valve - lined PTFE FEP PFA

Steel lined PTFE pneumatic ball valve - lined PTFE FEP PFA

Product parameters

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.

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.

Series selection and configuration options

Standard series sizeOriginal product range DN40–DN400; smaller or larger sizes can be evaluated as custom manufacture
Body material optionsStainless or carbon steel pressure-bearing body; PFA, FEP or PTFE are separate wetted lining options
Drive configurationPneumatic, single- or double-acting; limit switches, solenoid valve, filter-regulator and positioner can be selected

Standard series ranges and custom manufacture are separate. Smaller or larger sizes, special materials and tooling can be evaluated on request; design and quotation must be agreed. Not every size, material, seat and rating combination is interchangeable.

01 How should one compare valve brands and suppliers?
The manufacturing standards, material grades, pressure levels, leakage requirements, inspection documents, supply boundaries, delivery cycles and after-sales responsibilities should be compared based on the same technical conditions. If the technical conditions are different, comparing only the brand names or quotations would not be comparable.
