MODEL SJ-915 DUAL DISC CHECK VALVE

The Shurjoint model SJ-915 is a grooved-end dual disc check valve for pipelines conveying water and other fluids with the rated working pressure to 300 psi (20 Bar), available in sizes 14” to 24” / 350 mm to 600 mm.  The valve features a fully lined rubber body, spring-loaded 304 stainless steel disc and shafts.  The valve can be installed in a horizontal or vertical position (upward flow only).  Face to face dimensions conform to API 594 Class 150 and grooved ends to ANSI/AWWA C606.

* Working pressure is based on connection with roll- or cut-grooved standard wall carbon steel pipe.

Warning / Caution:

1. The valve is not intended for fluids containing suspended solids such as wastewater.

2. For horizontal installations, the valve must be positioned so that discs activate bisymmetrically as shown in fig. “A”.

3. The valves shall be installed with a distance of five (5) pipe diameters, minimum, downstream from the pump discharge, reducers or elbows.
