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 are available. Consult factory for configurations available for each model.
