They are superior in their abil-ity to overcome dirt and sticky oil during openingand closing, and operate smoothly even in an oil-free dry system. When electrically energized,the upstream pressure is ported through the pilotsolenoid to the top of the piston to push it down-ward and open the main valve seat wide; whende-energized, pressure is no longer ported to thetop of the piston and a spring closes the mainvalve seat to stop flow in the arrow direction onthe valve reliable, flanged bodied valves are ideal foruse as standard, stock refrigerant solenoid primarily for ammonia, these valves are alsosuitable for R22, R134a, and other approved refrig-erants and warm refrigeration oil.

2 Most commonuse is to automatically stop liquid feed to recircu-lating liquid overfeed evaporators, and as liquidmakeup solenoid valve for pump recirculators. Theyare also suitable for hot gas defrost supply andevaporator suction stop applications. (Note: Forgravity liquid drain or equalization applications,use low pressure drop HANSEN Type HCK2 gas-powered suction stop valves or Type HS9 Bgas-powered solenoid valves.)ADDITIONAL FEATUREST olerant of Dry SystemsTeflon Main & Pilot SeatsMolded HANSEN Standard CoilHeavy Duty, Pilot Operation300 psi MOPD ( bar)Simple Serviceable DesignAvailable Close-Coupled StrainerAvailable Close-Coupled Check ValveFor Ammonia, R22, R134a, and Other ApprovedRefrigerantsNon-Asbestos GasketsDimensionally Replaces Parker R/S S4A & S5 ACSA Certification AvailableKEY FEATURESF langed " thru 4"Weld End 5" & 6"for refrigerantsISO 90022 INSTALLATIONP rotect the interior of valve from dirt and moistureduring storage and installation.

3 Valve should beinstalled so that the arrow on the valve body is indirection of normal refrigerant flow. Valve will notprevent reverse flow; use check valves where nec-essary. System should be free from dirt, weld slagand rust particles. A 60 mesh, close-coupled straineris available for installation at inlet of valve; nosmall internal screens are used. Pipe sizing, rat-ing, anchoring, and similar prudent precautionsshould be taken to ensure liquid hammer will notoccur when valves open or close. For proper flangegasket sealing, care must be taken when threadingor welding to assure flanges are parallel to eachother and perpendicular to pipe. Also, gasketsshould be lightly oiled and all bolts must be tight-ened in 5" and 6" size are Type HS4W with inte-gral butt weld end only. These steel bodied sole-noid valves are directly welded into the pipe welding, the manual opening stem shouldbe opened downward several turns to protect theteflon seat from weld should be annealed as necessary in accor-dance with good practice.

4 Supplementary paintingof valves and welds is recommended for completecorrosion protection. Pipe covering, where ap-plied, should have proper moisture barrier. Beforeputting valves into service, all pipe connections,valve seats and seals should be tested for leaks atpressure levels called for in appropriate Dimensions4-5 Typical Applications6 Parts List7-10 Service and Maintenance11 Ordering Information12 ELECTRICALS tandard coil voltages are 115V, 208/230V, or 24V;50/60 Hz. Other voltages available, contact fac-tory. Coils draw 16 watts and will operate properlybetween 85% and 110% of rated voltage (24V coilsdraw 19 watts). All coils have a standard zincplated, steel housing which meets NEMA 4(splashproof) requirements; junction box coil isconsidered NEMA 1. Nameplate coil voltages shouldbe checked before wiring.

5 Coil should only beenergized while on solenoid tube; otherwise imme-diate coil burnout may occur. To avoid bendingthe solenoid tube, remove coil from valve beforeconnecting conduit fitting. Unless otherwise speci-fied, standard coil with " fitting for conduit willbe supplied with valves.

Their ductile ironbodies are stronger and more rugged than com-mon cast iron, including so-called semi-steel (classB iron) valves. They are more dirt resistant thanfull skirted piston designed valves and use a single,standard, power saving, low wattage coil that canbe used on all valve sizes. All valves incorporatereliable teflon seating and stainless steel springclosing. Non-asbestos gaskets are standard. Mainseats are stainless steel on 1 " and larger valves use a spring activated, teflon, dirt-wip-ing piston seal.

7 Manual opening stems are locatedon top of valves, up and away from dirt and rustparticles to extend stem seal life. This also facili-tates easier insulating of valves. Each valve isindividually packaged or sealed for valve interiorcleanliness and ease of storage until ready for valve boxes are clearly marked with catalognumbers and description. These valves are lengthdimensionally interchangeable with Parker R/S typeS4A & S5A solenoid valves (R/S 1 "= HANSEN 1 "4-bolt).3 LIQUID CAPACITIES (TONS)DDDDDDDDDDEZISTROP)mm(717R22R)P(PO RDERUSSERP)P(PORDERUSSERPISP2 ISP4 ISP2 ISP43/4")02(4612328204"1)52(003524254711 /4")23(1245953730111/2")04(9981721551022 "2)05(7021607190259221/2")56(77916972243 484"3)08(07626773264356"4)001(2624720673 73401R717 capacities based on 20 F ( C) liquid temperature and 5 F ( 15 C) evaporator temperature and no flashing throughvalve.
