Description

Irrigation 100 Series Plastic Hydraulic Control Valves

The BERMAD IR-100 hYflow is at the leading edge of control valve design, providing a valve that is free of the typical limitations associated with standard control valves.

A unitized flexible super-travel diaphragm & guided plug provide a significantly ‘look through’ passage resulting in accurate & stable regulation and ultra-high flow capacity.

The hYflow unique body design allows on-site adaption to a wide range of end connection types and sizes. Its articulated flange connections isolate the valve from pipeline bending & pressure stresses.

Valves up to 3″ can be converted to double chamber on-site.

Available in sizes:

Oblique (Y) – 1½”, 2″, 2″L, 2½”, 3″, 3″L, 4″, 4″L, 6″R & 6″ ; Angle – 2″, 3″, 3″L, 4″ “T” & Double (D) “T” patterns – 3″

Applications:

Irrigation Control Head
In-Field Control Head
LPS – Low Pressure Systems
Energy Saving Irrigation Systems
Computerized Irrigation Systems

Operation Modes

3-Way Control

Line pressure applied to the control chamber of the valve creates a hydraulic force that moves the valve to the closed position and provides drip tight sealing. Discharging pressure from the control chamber to the atmosphere causes the line pressure under the plug to open the valve.

2-Way Internal Control

Line pressure enters the control chamber through the internal restriction. The closed solenoid causes pressure to accumulate in the control chamber, thereby shutting the valve. Opening the Solenoid releases more flow from the control chamber than the restriction can allow in.
This causes pressure in the control chamber to drop, allowing the valve to open.
