Model 923-MV

The BERMAD Model WW-923-MV integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve.

The WW-923-MV sustains the preset minimum upstream pressure and reduces higher upstream pressure to lower constant downstream pressure, regardless of varying demand or upstream pressure.

Model 920-MV

The BERMAD Model WW-920-MV integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. The WW-920-MV reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure.

Model 9PM-MV

The BERMAD Model 9PM integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. The 9PM is a Flow Compensated Pressure Reducing hydrometer that automatically and continuously optimizes downstream pressure, correlating
valve setting with demand.

IR-900-E2

The BERMAD Automatic Metering Valve for Sequential Irrigation integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve, equipped with a mechanical sequential shut-off pilot. The BERMAD IR-900-E2 automatically shuts itself after accurately delivering a preset quantity of water. Working in a group of manually preset AMV’s connected to each other by a control tube and operating in sequence, it enables semi-automatic irrigation in non-computerized systems.

IR-900-D2

The BERMAD Automatic Metering Valve integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. Equipped with a Mechanical Shut-Off Pilot, the BERMAD IR-900-D2 enables volumetric irrigation in non-computerized systems. It automatically shuts itself after accurately delivering a manually preset quantity of water.

Model- 972-MV

The BERMAD Model WD-972-MV integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve.

The WW-972-MV has two independent functions: It maintains both pre-set maximum flow and reduces higher upstream pressure to lower constant downstream pressure, regardless of
varying demand or upstream pressure.

Model 910-MV

The BERMAD Model WW-910 integrates a vertical turbine Woltman-type water meter with
a diaphragm actuated hydraulic control valve.
The WW-910 either opens fully or shuts off in response to electric signals.

IR-920-D2-R

The BERMAD Pressure Reducing Automatic Metering Valve integrates a vertical turbine Woltman-type water meter, with a diaphragm actuated hydraulic control valve. Equipped with a Shut-Off Pilot and a Pressure Reducing Pilot, the BERMAD IR-920-D2-R reduces higher upstream pressure to lower constant downstream pressure. It automatically shuts itself after accurately delivering a preset quantity of water.

IR-923-D2-R

The BERMAD Mddel IR-923-D2-R integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. The BERMAD AMV performs three independent functions. It sustains the preset minimum upstream pressure; it reduces downstream pressure to a constant preset maximum, and it automatically shuts itself after accurately delivering a preset quantity of water.

IR-972-D2-RV

The BERMAD Model IR-972-D2-RV integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. The BERMAD AMV controls system demand to a preset maximum flow rate; reduces downstream pressure to a constant preset maximum, and automatically shuts itself after accurately delivering a preset quantity of water.

IR-930-D2-R

The BERMAD Model IR-930-D2-R integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. Equipped with a Mechanical Shut-Off Pilot and a Pressure Sustaining Pilot, the BERMAD AMV sustains minimum preset upstream (back) pressure. It automatically shuts itself after accurately delivering a preset quantity of water.
