Model 820

The Model 820 High Pressure PN 40, Pressure Reducing Valve is a hydraulically operated, piston actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure.

Model FP 400Y-2D

The BERMAD model 400Y-2D is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems, and the latest industry standards.
The 400Y-2D is activated by a 2-way solenoid valve,suitable for electric fire detection systems and is ideal for open nozzles with water or foam discharge.
Available with electric components to suit any hazardous location and offered with an optional visual valve position indicator that can include a limit switch suitable for Fire & Gas monitoring systems.

Model 823

Hydraulically operated control valve with independent Pressure Sustaining and Pressure Reducing functions. It sustains minimum pre-set upstream pressure, regardless of fluctuating flow or varying downstream pressure, and it prevents downstream pressure from rising above maximum pre-set level, regardless of fluctuating flow or excessive upstream pressure.
BERMAD 800 series valves are hydraulically operated, piston actuated globe valves designed for high pressure operation and available in either standard oblique (Y) or angle pattern design.

Their full bore hydrodynamic body provides an unobstructed flow path while their seat assembly and double-chamber unitized actuator can be disassembled without removing the valve body from the pipeline.

Model 820-PP

The Model 820-PP High Pressure, Proportional Pressure Reducing Valve is a hydraulically operated, piston actuated control valve that reduces higher upstream pressure to lower downstream pressure at a fixed ratio.

Model 830

Pressure relief/sustaining hydraulically operated control valve that can fulfill either of two separate functions:When installed in-line, it sustains minimum pre-set, upstream (back) pressure regardless of fluctuating flow or varying downstream pressure.

When installed as a “branched from the line” circulation valve it relieves excessive line pressure when above maximum pre-set.
BERMAD 800 series valves are hydraulically operated, piston actuated globe valves designed for high pressure operation and available in either standard oblique (Y) or angle pattern design.

Their full bore hydrodynamic body provides an unobstructed flow path while their seat assembly and double-chamber unitized actuator can be disassembled without removing the valve body from the pipeline.

Model 83Q

Hydraulically operated, piston-actuated, quick pressure relief valve that relieves excessive system pressure when such pressure rises above a pre-set value.
It responds immediately, accurately, and with high repeatability to a rise in system pressure by opening fully.

It also provides smooth drip tight closing.

BC-80F-P

 

The BERMAD BC-80F-P Strainer is designed to protect the pipeline and valves from large foreign objects, such as sticks and stones.
It is recommended to install the Strainer upstream from control valves, flow meters and other system components.

Model 80N

The Model 80N Check Valve is a non-slam, lift type, non return valve that opens to allow flow in the required direction and smoothly closes drip tight to prevent back flow.

Model 840

The Model 840 High Pressure, Booster Pump Control Valve is a hydraulically operated, piston actuated active check valve that opens fully or shuts off in response to electric signals. It isolates the pump from the system during pump starting and stopping, to prevent pipeline surges.

Model 835-M

The Model 835-M High Pressure, Surge Anticipating Valve is an off-line, hydraulically operated, piston actuated valve. The valve, sensing line pressure, opens in response to the pressure drop associated with abrupt pump stoppage. The pre-opened valve dissipates the returning high pressure wave, eliminating the surge. The Model 835-M smoothly closes drip tight as quickly as the relief feature allows, while preventing closing surge. The valve also relieves excessive system pressure.

Model 843

The Model 843 High Pressure, Booster Pump Control & Pressure Sustaining Valve is a hydraulically operated, piston actuated active check valve that opens or shuts off in response to electric signals.

It isolates the pump from the system during pump starting and stopping, to prevent pipeline surges. While open, it sustains minimum discharge pressure or pump differential pressure regardless of fluctuating flow.
