Valveworks check valves effectively prevent backflow in high-pressure treating, fracturing, and well-servicing operations.
Designed for reliability, our check valves ensure a secure seal in all conditions and can be customized with paint and configurations to match your job site needs.
For durability, the flapper and seat of our swing check valves feature titanium nitride coating, while the dart check valve operates with an independent, pressure-actuated response system.
