Technical Data
Reliable Single Interlock Preaction Systems, with associated
trim, size 2” (50 mm), 2½” (65 mm), 76 mm, 3” (80 mm), 4”
(100 mm), 165 mm, 6” (150 mm) & 8” (200 mm) are rated
for use at minimum water supply pressure of 20 psi (1.4 bar)
and maximum supply pressure of 250 psi (17.2 bar) for 2”
(50mm), 2½” (65mm), 76mm, 3” (80mm) and 8” (200mm)
valve sizes and 300 psi (20.7 bar) for 4” (100mm), 165mm and
6” (150mm) valve sizes. Water supplied to the inlet of the valve
and to the pushrod chamber must be maintained between 40°F
(4°C) and 140°F (60°C).
