IR-420-55-bK

The BERMAD Model IR-420-55-bK is a hydraulically
operated, diaphragm actuated control valve that accurately
reduces higher upstream pressure to very low and stable
preset downstream pressure regardless of fluctuating
demand, or varying upstream pressure. It either opens or
shuts in response to an electric signal.

IR-423-XZ

The BERMAD Model IR-423-XZ Pressure Reducing and
Sustaining Valve is a hydraulically operated, diaphragm
actuated control valve with two independent functions.
It sustains minimum preset upstream pressure regardless
of fluctuating flow or varying downstream pressure, and it
prevents downstream pressure from rising above maximum
preset regardless of fluctuating flow or excessive
upstream pressure.

IR-420-bKZ

The BERMAD Pressure Reducing Valve is a hydraulically
operated, diaphragm actuated control valve that reduces
higher upstream pressure to very low and stable preset
downstream pressure regardless of fluctuating demand,
or varying upstream pressure.

Model 42T-20

 

The BERMAD model 42T-20 is an elastomeric, hydraulically operated, self actuated Non Return Fire Pump Pressure Control Valve, designed for advanced fire protection systems meeting the NFPA-20 guidelines.

The 42T-20 is used for controlling the flow and pressure at the pump discharge, performing also as a non return check valve.

The 42T-20 prevents pump startup surge, typically caused by the accelerated water flow during the fire pump starts.

The valve also helps to prevent pump start negative suction pressure, preventing pump cavitation damage.

Due to exceptional reliability, safe actuation and low head loss, the 42T-20 is highly suited for fire pump discharge pressure control applications.

As an option the 42T-20 can be fitted with a valve position indicator that can include a limit switch suitable for industrial monitoring systems.

IR-450-60-R

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.

IR-450-65-Z

The BERMAD Model IR-450-65-Z Level Control Valve with Bi-Level Electric Float is a hydraulically operated, diaphragm actuated control valve that controls reservoir filling in response to an electric float switch signal, opening at pre-set low level and shutting at pre-set high level.

IR-450-66-Z

The BERMAD Model IR-450-66-Z Level Control Valve with Bi-Level Vertical Float is a hydraulically operated, diaphragm actuated control valve. The valve is hydraulically controlled to fully open at preset reservoir low level and to shut at preset high level.

IR-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.

BC-453-65-P

Hydraulically operated, level control and pressure sustaining control valve that controls reservoir filling and reservoir level. During filling the valve sustains minimum upstream pressure regardless of fluctuating flow or reservoir level.
Reservoir filling is in response to a Bi-level electric float switch signal opening at a pre-set low level and shutting off at a pre-set high level.
BERMAD 400 series valves are hydraulically operated, simple and reliable, globe valves with full bore hydrodynamic body providing an unobstructed flow path and superior performance.
The valves balanced rolling-diaphragm assembly is vulcanized with a rugged radial seal disk construction, performing as the valves only moving part.

BC-450-80-P

Hydraulically operated control valve that controls reservoir filling and reservoir level.
The valve shuts off at a pre-set reservoir high level and fully opens in response to an approximately one meter (3 ft) level drop, as sensed by the 3-Way altitude pilot mounted on the main valve.
BERMAD 400 series valves are hydraulically operated, simple and reliable, globe valves with full bore hydrodynamic body providing an unobstructed flow path and superior performance.
The valves balanced rolling-diaphragm assembly is vulcanized with a rugged radial seal disk construction, performing as the valves only moving part.
