KINDS OF RESILIENT GATE VALVES: NONRISING STEM GATE VALVE & RISING STEM GATE VALVE
Fig. 719R
Design on its nominal diameter to give a clean way with out sedimentation. Its seal is by compression betwen the disc cover with resilient material and the lower part of the valve according to the AWWA-C-509 low for a work pressure (200 lb/pulg2) 14 Kg/cm2 with a maximum temperature of 90°C (194°F)
| NOTE: When you press a number on the valve plane the description about this will appear at the top of the screen |
