Basic Valve 300 Series
I?R??-?3?0??0 Basic Valve
The BERMAD basic diaphragm actuated Model IR-300/305 valve is
a hydraulically operated globe valves in either the standard oblique (Y)
or angle pattern design in diameter sizes of 11/2-3”; DN40-DN80. Each
valve comprises two major components: the body seat assembly and
the actuator assembly.
The actuator assembly is unitized and is removable from the body as
an integral unit. It consists of both an upper and a lower control chamber.
Each basic valve can easily be configured, on-site, either as a single
chamber control valve (Model 305), or a double chamber control valve
(Model 300). The shaft sub assembly, in both single and double
chambered versions is center guided, providing an unobstructed seat
area.
The Model 300 Basic double chambered valve operation is independent
of valve differential pressure since the line pressure actually serves as
the actuator differential pressure. This develops maximum power,
ensuring immediate valve response. The upper control chamber is
pressurized to close, and vented to open the valve. The lower control
chamber is usually vented to the atmosphere, but can also be pressurized
to power the valve open.
The main benefits of the double chambered valve are:
Full-powered opening & closing
Decreased pressure loss (no spring)
Non-slam closing characteristic
Isolated and protected diaphragm
The Model 305 Basic Valve uses valve differential pressure to power
the actuator open or closed. The lower control chamber, which serves
to cushion the closing of the valve, is exposed to the downstream
pressure, through a fixed orifice connected to the downstream side of
the valve. The pressure in the upper control chamber varies, resulting
from the action of a solenoid or a regulating pilot. This varying pressure
modulates the valve to open or close.

On-Off Modes
Principle of Operation
Closed Position
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.
Open Position
Discharging the pressure from the control
chamber to atmosphere or some other
lower pressure zone, causes the line
pressure acting on the seal disc to move
the valve to the open position.
Normally Closed Valve with Hydraulic Power Opening
Line pressure is applied constantly to the Upper Control
Chamber (UCC). When the Lower Control Chamber (LCC)
is vented, it allo
