Check pressure rating and dimensions of Polytetrafluorethylene Check Valve

Fit-lok is trusted PTFE check valve manufacturer in India in different sizes and pressure rating. These valves are known for withstanding high pressure and temperature rating. These valves are well suited for harsh chemical and corrosive/caustic media and environments. Fit-lok offers Teflon ball valves or alternative chemical check valves built to withstand demanding operating conditions. The valve bodies together with ports and stems utilize PTFE as the main construction material to deliver an all-wetted-surface high purity solution. The standard requirements for non-wetted exterior components use Polypropylene and natural PVDF material fabrication.

The PTFE lined swing check valve has two ports to enable unidirectional gas flow while blocking backward movement. The device allows simple customization for different application needs. The properties of Polytetrafluorethylene Check Valve make them suitable for various industrial applications. These valves requires minimum maintenance and can be used for longer period of time.

We are one of the most renowned supplier and exporter of Teflon Check Valve to the different industries like Oil and Gas, Petroleum industry, seawater desalination plants around the world.
