Level Control Valve

The BERMAD Model IR-450-80-XZ Level Control Valve with Altitude Pilot is a hydraulically operated, diaphragm actuated control valve. The valve hydraulically shuts at preset reservoir high level and fully opens in response to an approximately one-meter (three-foot) level drop, as sensed by the 3-way altitude pilot mounted on the main valve.
