The BERMAD 200 Seriesplasticcontrol valves range from 3/4" to 2" in
size, in either globe or angle pattern.
These control valves provide superiorhydraulic performance, constituting
as they do, the state-of-the-art in
hydraulics and in plastic technology.
FEATURES Constructed of corrosion-resistant,
high engineering plastics, synthetic
rubber and stainless steel parts. Very high flow rate with very low head
loss.
Operation over a wide range of
pressures.
Smooth valve opening and closing
prevents pressure surge hazards.
Self-cleaning orifice on electric
models provides reliable valveoperation, even with brackish water.

The BERMAD 300 SeriesY-pattern and angle, diaphragm-actuated control valves areavailable in 11/2", 2" and 3" sizes.This control valve provides highflow capacity with versatile andaccurate double-chamberedactuator.The valve can be operated in threeoptions: Hydraulic or electric On/Off
remote control valve. Pressure reducing or pressure
sustaining/relief control valve. Combination of the two first
options.
FEATURES Y-pattern body, which provides
high flow with low head losses. Hydraulically operated bydouble-chambered diaphragmactuator, which provides highversatility of applications and acushioned, no-slam closure.
Low sensitivity to dirt. On/Off operation as well as
throttling operation.

350 Series
FILTER BACKWASH HYDRAULIC V
For filter systems
TheBermad 350 SeriespatentedFilter Backwash Hydraulic Valvesare suited for automaticbackwashing of filtration systems.
They are diaphragm-actuated,compact, 3-port valves, in the Tee
configuration. Their simpleconstruction and few parts ensuresmooth operation and long,trouble-free service. Thediaphragm-actuated plugassembly keeps the supply portclosed while opening thebackwash port and vice-versa.Short travel guarantees smooth
changes of flow direction,conserves water supply, prevents
filter site flooding and eliminatesmixing of supply and waste water.At the end of its stroke, the 350Series seals the port drip-tight.Incorporating Bermad's time-provencontrol valve technology and high
performance standards, the 350Series has no bearings to serviceand no intricate rolling diaphragmsto replace.
The 350 Series valve is availablein two models:
Single-Chambered Type- suitedfor angle pattern flow requirements
Double-Chambered Type -suitedfor straight and angle pattern flowrequirements

through hydraulic remotecontrol tubes.
The HYDROMETER (W)isavailable in a variety of
different models for amultitude of applications. Theturbine-type water metermeasures flow with anaccuracy of 2%, while thebuilt-in control valve performs,simultaneously, On/Off orpressure/flow regulating

900WM MAGNETIC DRIVE HYDROMETER
The Model 900WM integrates aWoltman-type vertical turbine watermeter and a basic diaphragm-actuatedcontrol valve. The vertical turbine
impeller drive is magnetically coupledto the vacuum-sealed meter register inthe control head. Both the magnetic-drive control head and its register aresealed (completely dry) and are notaffected by dirty water conditions. Thehighly sensitive magnetic-drive providessuperior accuracy that exceeds all watermeter standards. The available controlhead options provide increased dataas well as greater flexibility in electricalpulse generation/ transmissions.

Pulse Generating OptionsThe reed-switch pulse transmitter is a magnetic on/off
switch that produces an electric pulse per unit of volume.
An obvious choice for high flow conditions, the highlyaccurate, infrared retro-reflective photocell (opto) pulse
Electric Pulse Generating OptionsEach hydrometer is capable of generating 2 simultaneous outputs.The hydrometer can be factory configured as standard or optional.This table shows the possible combinations.
transmitter produces a verhas unlimited pulse rate catransmitted to a converter tor pulse counting.

The exclusive AR Series, plasticand metal manufactured productsoffer outstanding features andadvantages: Perfect sealing under very low
system pressure.
High flow capacity.
Patented operation together withsmart design.
Simple, compact and reliableproduct.
The BERMAD AR Seriesair andvacuum release valves include fourbasic models:
1" Automatic pressure air releasevalve (Model 01-ARA),for theautomatic release of entrapped airpockets from pressurized systems.
2" Kinetic air and vacuumrelease valve (Model 02-ARK),with large orifice, for the releaseof large quantities or air from fillingpipelines and for admitting air intoquick-draining pipelines to
prevent vacuum damage.2" Combination air andvacuum release valve (Model02-ARC),in which the featuresof the two previous models areincorporated in one single valvebody, for safe pipeline filling anddraining and for releasing air
pockets during system operation.1/2" Vacuum breaker (ModelARV),prevents drip lines fromclogging in tough topographicconditions and in sub-surfacedrip-irrigation system.

PC Series
HYDRAULIC PILOT VALVESAND CONTROL ACCESSORIES
PC-XMULTI-PURPOSEPILOT VALVEThis 3-way pilot valve has been designedto control hydraulically operated controlvalves.
The PC-Xpilot valve is characterized byexceptional control versatility: bychanging control ports, the same pilotvalve will convert a hydraulic valve intoa pressure reducing or pressuresustaining/relief control valve.
Using a PC-Xpilot valve which vents tothe atmosphere for pressure regulationhas the advantage of fully opening themain valve when operating conditions
call for minimum pressure loss.
The PC-Xpilot valve can also be usedas a hydraulic relay for separating thehydraulic remote signal from theoperating pressure in the local valve,thus overcoming difficult topographicand hydraulic remote controlconditions.
PC-20PRESSURE REDUCINGPILOT VALVEThis 2-way pressure reducing pilotvalve modulates the opening of thehydraulic control valve for reducinghigh supply pressure to a lower,constant downstream pressure,regardless of changing operation
conditions.The PC-20pressure reducing pilotvalve is typically employed inBERMAD's pressure reducing controlvalves with 2-way modulating controlloops.
