Level Control Valvewith Altitude PilotIR-450-80-XZ 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. ■ Line Pressure Driven, Hydraulically Controlled ■ Bi-Level Altitude Pilot □ No float, simple installation □ On/Off service □ No cavitation damage □ Suitable for low quality water ■ Advanced Globe Hydro-Efficient Design □ Unobstructed flow path □ Single moving part □ High flow capacity ■ Fully Supported & Balanced Diaphragm □ Requires low opening and actuation pressure □ Progressively restrains valve closing □ Prevents diaphragm distortion ■ User Friendly Design □ Easy level setting □ Simple in-line inspection and service [1] Typical Applications ■ High Level Reservoirs and Water Towers ■ Unavailable Power Supply Locations ■ Low Supply Pressure Systems ■ Low Noise Generation Requirements ■ Energy Cost-Critical Systems ■ Systems with Poor Water Quality ■ Level Sustaining at Reservoir Outlet [1] BERMAD Model IR-450-80-XZ shuts at reservoir preset high level and fully opens in response to an approximately one-meter (three-foot) level drop.
