General
The FLSmidth Two-Gate Valve provides a dual-gate airlock seal against a differential pressure up to 17” W.G. and will withstand material temperatures up to 400°F (205°C). For material temperatures to 700°F (371°C). special motors and heat shields can be provided at extra cost.

Body
The valve body is constructed of seven (7) gauge fabricated steel plate. Inspection plate cover permits easy service access.

Gates
The FLSmidth Two-Gate Valve has two (2) sealing gates which alternately open and closes as material passes through the unit in order to maintain a seal between material inlet and outlet. The alternating cycle is mechanically operated using an eccentric and gear motor arrangement. Simple gravity release produces non-jamming return operation. Steel gates are mounted on a finished shaft rotating freely on outboard self-aligning ball bearings.

Motor Gear motors are TEFC, 3 phase, 230/460 Volt AC, 60 Hz.
