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

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

AR SeriesAIR AND VACUUM RELEASE VALVEFor waterworks, irrigation and turf systems

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.
