    PRODUCT OVERVIEW

    The same HUNTER quality found in all ofour remote control valves is also found inthe PGV family. This Professional GradeValve is a solid, heavy-duty performerdesigned to satisfy the requirements of themost demanding job sites.

    Meets the Needs of AllResidential/Commercial ProjectsThe versatility of the PGV valve is theanswer to anyone who demands options.The valve is offered as an angle, globe orglobe/angle combination in a full range ofsizes, including 1" with or without flowcontrol, 11/2", and 2". Flow capabilityranges from a low of 1 gpm (0.23 m3/hr,3.8 l/m) all the way up to 120 gpm(27.2 m3/hr, 454.2 l/m).

    Available as an option, the HunterAccu-Set valve pressure regulator is animportant tool for the professional installer.The Accu-Set is the product of choice forinstallation on PGV valves when the staticsupply pressure is just too high for sprinkleroperation or when the irrigation main linesneed to be at maximum pressures due tolong pipe runs. Also, the Accu-Set is theideal pressure regulator to use when differentirrigation zones require different outletpressures due to product specifications, suchas sprays and rotors. Easy to install and easyto read, this dial-in pressure regulatingmodule automatically adjusts as needed toprovide an accurate and consistent workingpressure in the zone piping.

    Designed for Years of LifeHunter developed the PGV valve with itsmultitude of features, because of a marketneed for a strong product with dependableperformance.

    The rugged, extremely tough body andbonnet contribute to a high pressure rating of150 psi (10.3 bars, 1034 kPa). In addition,the valve features captive bonnet screws,

    diaphragm and a captive solenoid plunger.Plus, the heavy-duty Hunter solenoid, withits 5-year warranty, is sure to keepeverything working for years and years.

    Easy to Install, Easy to MaintainMaintenance is an ongoing reality to anyproject and like all Hunter products, theeasy-maintenance PGV was designed withthe installation and service needs of theprofessional installer in mind. Offering aglobe/angle configuration in one valveallows the installer to readily place the valvefor easy access. The PGVs diaphragm,solenoid plunger, and bonnet screws are allcaptive parts, eliminating the chance of lostparts. Through-holes in the body allow dirtto fall through the screw holes instead ofallowing it to pack at the bottom, where itcan make it impossible to tighten the screwupon reassembly.

    The bonnet screws used in the PGV lineare unique to Hunter valves. These screws,specifically designed for use in plastic,thread quicker and truer into the valvebody. They are compatible with a varietyof tools: a hex nut driver, a Phillips screw-driver or slotted screwdriver for easyservicing. When installing irrigationsystems, something as simple as a bonnetscrew design is all that it takes to savetime and money.

  • FEATURES ANDBENEFITS

    Globe or Angle ModelsFlexibility in design

    Many times the irrigation main line isinstalled much deeper than the systemslateral lines. This may be due to localcodes or for freeze protection. For thesesituations, Hunter offers 11/2" and 2"valves with a globe/angle configuration inone valve. The globe configuration offersthe best choice for those systems that havethe main line at the same depth as thelaterals. The angle configuration allowsthe installer to place the valve on top of adeep main line, which allows easy accessto the valve for maintenance.

    In addition, the PGV angle configurationboasts a lower pressure loss across thevalve compared to a globe style valve,providing a big advantage on systems thatmay experience low operating pressures.

    Body OptionsMaximum choices, minimum effort

    Hunter is aware of the many differentvalve requirements that are prevalent intodays irrigation market. With that inmind, the PGV is designed as a veryadaptable valve in the residential/commercial market. The PGV is availablewith a variety of inlet and outlet sizes andconfigurations: NPT, BSP, Male x Barb,Male x Male, and Slip.

    The barb outlet valves have become aninstant hit in the colder regions of the US,where polyethylene pipe is frequentlyused for laterals. Contractors report theirinstallation times have decreased tremen-dously when this valve is used on theirjobs. Eliminating the addition of an extraadapter or two to the manifold not onlysaves time and money, but also saves onthe possibility of leaks.

    Barbed ConnectionsPoly pipe connectionsmade easy

    An overwhelming requestby Hunter valve userswas to develop a valvewith a barb outlet connectionbuilt into the valve for poly pipe users.Hunter responded with four 1" models tochoose from. The 1" globe with flowcontrol in MNPT and MBSP threads andthe 1" globe without flow control in bothMNPT and MBSP threads are nowavailable. With all of these models, thetime-saving benefits have proven to besubstantial for the installer, because they nolonger need to thread adapters or nippleswrapped with Teflon tape into the valve toattach to poly pipe systems.

    Flow RangeHighly versatile valve for all flowrequirements

    The flow range of the PGV is exactly whatinstallers are looking for in 1", 11/2", and 2"valves. Systems requiring a flow rate aslow as 1 gpm (60 gph), such as for low-volume irrigation, are easily accommodatedwith the 1" PGV. Also, irrigation systemsrunning up to 120 gpm per zone, which canbe found on large commercial sites, arewell within the 2" valves designedcapabilities.

    High-grade materials used for a150 psi ratingMade of durable materials to resist wear

    If you are in the market for a valve thatneeds to take the pressure, the PGV is yourchoice. Featuring solid heavy-dutyconstruction built with an ABS skirtedbonnet, this valve takes up to a constant150 psi without regard to hot summertemperatures. The superior design of thePGV helps eliminate any reduction inperformance when temperatures go up: acommon occurrence with 100% PVCconstructed valves.

  • Captivebonnetscrews

    Heavy-duty SolenoidProvides dependable operationand long life

    The entire line of Hunter valves hassomething in common: the same heavy-duty five-year warranty solenoid. Install-ers will find that not having to stock twoor three different solenoids for valves ofthe same manufacturer are a real plus.Another plus is the solenoids captiveplunger, which enables easy servicing ofthe solenoid but eliminates the chance forany lost internal parts.

    It only takes 11/2 turns to remove orreplace the solenoid which makes twistedsolenoid wires a non-issue (a tremendousbenefit to installers or maintenance peoplewho work with valves).

    The Hunter solenoid is unique becauseit operates on a reverse flow principle. Thecenter hole in the solenoid bowl is an inletport, instead of an exhaust port. Wheninstalling long wire runs, this solenoid isvery efficient, especially under highsystem pressures.

    A big advantage to this reverse flowaction is that it reduces potential largepressure spikes against the valve. Suchspikes could cause damage not only to thevalve, but to other components of theirrigation system as well. With the PGV,when a surge pressure spike hits the closedvalve, the solenoid plunger will openslightly to allow the spike to traveldownstream and dissipate through thezone piping, minimizing any damage thatcould occur. The solenoid plunger thencloses immediately, preventingunscheduled system operation.

    Captive Bonnet Screws, Diaphragm andSolenoid PlungerNo lost parts duringservicing

    When servicing is required,the PGV is the valve thatmakes it easy. The screws,captive within the bonnet, aredesigned to be removed by anut driver, Phillips, or slottedscrewdriver. Another uniquecharacteristic to the PGV lineis the type of screw used.Specifically designed for usein plastic, the screw sports alarge thread gain, allowing it to threadquicker and truer into the valve body.

    In addition, all parts are captive withinthe solenoid (a great feature in a valve,assuring those parts
