ACCESSORiES
The Figure S853 “Y” Strainer is rated for 4,413 kPa (640 psi) at 38°C (100°F) and 1,034 kPa (150 psi) at 296°C (565°F) . The “Y” Strainer provides economical strainer protection for piping equipment such as pumps, meters, valves, compressors, and traps . The inlet and outlet ends are suitable for installation with Figure 705, 707, and 772 Couplings .
The Figure S853 “Y” Strainer screen has the following standard perforations:
• Sizes 50mm – 100mm (2" – 4") = 1 .6mm (1⁄16")
• Sizes 125mm – 300mm (5" – 12") = 3 .2mm (1⁄8")
All covers have an NPT blow-off outlet (pipe plugs not included) and recessed seat in the cover to ensure screen alignment .
Self-cleaning occurs by opening the valve (not supplied) connected to the blow-off outlet . Indicate when ordering strainers that are mounted in vertical piping so that the cover will be rotated to position the blow-off at the lowest point .
Note: Pressure and temperature can be limited by gasket material. Contact GRINNELL Mechanical Products.
