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.
· Suggestions: For complete shutoff, a shutoff valve (plug valve) should be connected in series with the check valve. The top-entry type and in-line flapper type check valves should be installed horizontally and smoothly.
