Dart Type Check Valve

Dart Style Check Valve is a special non-return (one-way) valve designed as per to work under extremely high pressure and temperature in oilfield development facilities.  Dart type Check Valve usually consists of valve body, seal rings, lock nut, spring, sealing gland, O-rings, and plunger. Dart Check Valves are considered reliable during various oilfield operations, such as cementing, acid stimulation, well kill works, hydraulic fracturing, well clean-up and solid management, etc.

Being another type of check valves, dart check valve perform the same function as any other check valves; allowing fluids enter from one opening and blocking the back flow of fluids from another opening. In other words, dart check valves allow fluids (liquid or gas) to flow through in only one direction.
