Weco check valves are used to isolate well-servicing equipment from high-pressure treating fluids during fracturing applications. Offered in three primary models, these rugged valves seal against a complete range of well-servicing fluids at pressures to 20,000 psi. Valves are available in 1-1/2 to 4-inch bore sizes for standard and reverse flow. Sour gas models available. Consult factory for configurations. Like all pressure containing products, Weco check valves require special handling.
