Check Valves

Check valve in the high-pressure fluid pipeline to prevent fluid reflux, control the one-way flow of media in the pipeline, to protect the pipeline and equipment safety. Check valve internal core components are made of stainless steel processing, with wear-resistant and corrosion-resistant. The seals are vulcanized twice, with good sealing. We can provide customers with three types of check valves: baffle type, linear baffle type and dart type check valve. The baffle type single flow valve is generally used for liquids or liquid-solid mixtures, and the dart type is generally used for gases or low-viscosity pure liquid conditions.

Product Features

· Check valves are used in high pressure lines to control one-way flow and prevent fluid from flowing back in pipeline, while protecting the pipe line and equipment safety.

· AIFUEL offers check valves with two flow directions: standard flow direction with the union in front and reverse flow direction with the thread in front;

· The core component of check valve is forged by stainless steel with advanced erosion and abrasion resistant characteristics;

· The seal has its own intellectual preperty, with excellent performance;

· Three styles are provided: top-entry check valves, in-line flapper check valves and dart check valves.
