Pneumatic PTFE Lined Gate Valve

A GMK pneumatic Pneumatic PTFE Lined Gate Valve, a straight single seat fluoride (PTFE) Lined construction, and a pneumatic diaphragm is the component components that make up the pneumatic PTFE lined control valve. The pneumatic PTFE lined gate valve may be disassembled into its component parts. In the pneumatic PFA lined control valve that is in contact with the corrosive medium, the corrosion-resistant, anti-aging, high-pressure lining fluorine plastic technology is used. This allows for the control valve to function optimally for a longer period of time. Taking this method also has a number of additional advantageous repercussions.

The GMK pneumatic PTFE-coated control valve is capable of controlling the flow of liquid and corrosive media such as acid, alkali, aqua wang, and other highly corrosive media. This control valve can also regulate the flow of toxic volatile gas. In addition, the control valve is able to regulate the flow of the potentially lethal volatile gas. In addition to that, it is able to regulate the circulation of liquid media. Because of this, the pneumatic PTFE-coated valve is used often in a wide range of sectors. Some examples of these industries include the metallurgy industry, the medical business, and the chemical industry, amongst others.


  • The body, core, and seat of a pneumatic fluorine-lined control valve are coated with a 3mm thick layer of fluorine (PTFE), making them very resistant to corrosion.
  • The PTFE bellows and packing provide double-sealing, ensuring a leak-proof seal.
  • Third, the Pneumatic fluorine lined control valve core and seat are soft seals, so there is very little leakage. This is much below the national IV-level norm.
  • Pneumatic fluorine-coated control valves use compact and lightweight pneumatic or electric actuators, allowing for finely nuanced adjustments.
