Victaulic has extended the size range of its Series 713 swing-check valve to include 2- to 4-in. sizes. The additional sizes enable the grooved-end check valve to be used on a wider range of high-pressure piping systems, offering operators quick, simple installation and maintenance. The Victaulic Series 713 swing-check valve offers higher working pressures than previous designs, for greater versatility. Designed for headers that feed upstream facilities as well as other high-pressure services, the valve can be used in applications requiring Class 300 pressure ratings. The 2-in. valve is rated to 1,000 psi, while the 2½-, 3-, and 4-in. sizes are rated to 750 psi. Featuring grooved ends, the Series 713 swing-check valve is joined by use of Victaulic couplings, enabling quicker and easier installation and maintenance than flanged valves. The valve can be joined to pipe with the Victaulic Original Groove System or EndSeal grooved ends. The valve is designed for use in horizontal installations and can be coated for use in corrosive services.
