300H Series
The Phillips Series 300H internal mounting fixed level low side float valves are modulating type liquid level controls, designed primarily for use with ammonia (R-717). The valves incorporate a replaceable cartridge that contains the working needle and seat. The cartridge can be removed without pump down of the surge drum or evaporator due to a secondary shut-off arrangement built into the valve. When greater capacities are required, these valves can be used as pilot float valves in conjunction with Phillips Series 701 Pilot Operated Valves. See Bulletin 701S-FL.
300H Valve Series includes 300H, 300HM, 300A and 300AM
