Bermad Model 450 - 60 - 2 way Level Control Valve

The BERMAD Model IR-450-60-R Level Control Valve with Modulating Horizontal Float is a hydraulically operated, diaphragm actuated control valve. The valve hydraulically controls reservoir filling to maintain constant water level regardless of fluctuating demand.


Features and Benefits

  • Line Pressure Driven, Hydraulically Controlled
  • Modulating Hydraulic Float Control
    - “Always Full” reservoir
  • Advanced Globe Hydro-Efficient Design
    - Unobstructed flow path
    - Single moving part
    - High flow capacity
  • Fully Supported & Balanced Diaphragm
    - Requires low opening and actuation pressure
    - Excellent low flow regulation performance
    - Progressively restrains valve closing
    - Prevents diaphragm distortion
  • External Installation
    - Easy access to valve and float
    - Less wear and tear
    - Simple in-line inspection and service

[1] BERMAD Model IR-450-60-R opens upon drop in reservoir level maintaining “Always Full” reservoir, and shuts on rise in reservoir level to preset high.

Bermad Model 450 - 60 - Level Control Valve - Operation

The Needle Valve [1] allows continuous flow from Valve inlet into the Control Chamber [2]. When water level rises, it pushes the Float [3] up throttling the Float Pilot [4]. Pressure in the control chamber accumulates, causing the Valve to throttle closed, reducing filling rate, and eventually closing drip tight. Should level fall, the float pilot releases pressure from the control chamber causing the Valve to modulate open. The needle valve controls Valve closing speed. The Cock Valve [5] enables manual closing.
