1 FP/FS 400Y Torrent Vlve Engineering Dt Description The BERMAD FP/FS-400Y Torrent vlve is esigne specificlly for the fire protection inustry, with n emphsis on rugge relibility n high performnce to comply with the most emning stnrs. A stright-through, hyrulic, line pressure riven, elstomeric, rolling iphrgm globe vlve pprove for 25 br/365 psi with n inustry-leing flow rte. It is eqully suite to verticl or horizontl instlltion n is vilble in pipe imeter sizes from 1½ to 16 (DN40 to DN400). The BERMAD 400Y is esigne for flow control in eluge, pressure control eluge, remote on-off, monitor remote control, pre-ction systems, pressure reucing n pressure relief. It is excellent for ll fluis use in fire protection systems, from fire-wter supplies to fom solution, sewter, fom concentrte n other corrosive liquis. It cn be mnufcture from vrious mterils n cotings to suit wie rnge of specifictions n hzrous loctions. It is certifie n pprove to the ltest fire protection stnrs. The 400Y s unique hyroynmic Y shpe esign provies very high flow cpbilities with miniml he loss. It inclues strightthrough Y-type boy, with n unobstructe flow pth, free of ny supporting cge, in-line ribs, or shfts. FM APPROVED Ptent Pening Proviing resilient, rip-tight seling, the internl esign of the vlve is bse on innovtive Vulcnize Ril Sel Disk technology (VRSD) tht uses vnce rubber-bse mterils to chieve soli, single-piece, elstomeric unit. This is compose of flexible, fiber-reinforce iphrgm vulcnize with rugge, ril sel isk. It is crefully blnce n peripherlly supporte to voi tension n protect the elstomers, resulting in long life n epenble ctution, even uner hrsh conitions. Quick in-line inspection n servicing is enble by etchble vlve cover. The elstomeric ssembly cn esily be remove without tking the vlve out of the line or removing the trim. Fctory Fitte Options Locl vlve position inictor becon: The vlve cn be equippe with protective-covere, ul-color, qurter turn position inictor, reble from istnce of 50 meters Vlve Limit Switches n position monitoring evice: A limit switch unit with ul SPDT limit switches enclose in protective switch box tht cn interfce for monitoring ny Fire & Gs control system. The switch box incorportes ul-color visul position inictor. Swivel Drin Vlve unit: Instlltion in confine spces is fcilitte by the 360 egree swivel bility of the rin vlve connections. Set Insert (coe T) The set insert option is esigne for pplictions where there is high potentil for cvittion mge. Specify this option for pressure control pplictions hving high pressure ifferentils or for relief vlves hving tmospheric ischrge up to 175 psi / 12 br. The set insert option is lso recommene for incresing the vlve boy lifetime. Sewter resistnt (coe FS) The vlve boy n cover cn be cst in vrious lloys to provie the require resistnce to corrosive internl flui, such s sewter, or to corrosive externl environment, s with offshore pplictions or costl environments. Corrosion resistnce cn lso be provie by coting uctile iron or steel vlves with highbuil fusion bone epoxy with UV protection. 1

The vlve cn be cst in vriety of corrosion resistnt lloys, offering the highest resistnce to corrosive internl fluis or externl environments. To enble higher corrosion resistnce for uctile iron or steel vlves UV protecte fusion bone high buil epoxy coting is optionl.

6 (2) (1) FP 400Y Principle of Opertion ON/OFF Opertion In the close position (Fig 1): The wter pressure supplie through the priming line (2) is trppe in the control chmber (1) by the operting vlve (3) pressing the sel isc (4) own n thereby seling the vlve n keeping the system piping ry In the open position (Fig 1b): Pressure is relese from the control chmber by wy of the operting vlve (3), which cn be ctivte either electriclly, hyruliclly, pneumticlly or mnully. With no pressure in the control chmber the sel isc will open n llow n unrestricte wter flow through the vlve into the to the system piping. Electric, Hyrulic, Pneumtic (4) or Mnul Opertion (3)(1) Mnul Electric Hyrulic Pneumtic (6) (2) (2) (5) (1) (4) (3) Fig 1: Vlve Close (Sttic Conition) Fig 1b: Vlve Open (Flowing Conition) Pressure Control The BERMAD 400Y Torrent vlve is highly suitble for pressure regultion in fire protection pplictions either for Pressure Reuction - Moel 42T or for Pressure Relief - Moel 43T. The BERMAD Moel 42T reuces wter pressure utomticlly n ccurtely from higher inlet vlue to lower set outlet vlue. It opertes uner both flow (Fig 2b) n non-flow (sttic) conitions (Fig 2). The pressure-reucing pilot vlve [3] senses chnges in outlet pressure n moultes pressure in min vlve control chmber [1] to mintin the set outlet pressure. When outlet pressure rises bove the set pressure: The pilot vlve throttles cusing wter pressure to ccumulte in the control chmber (1) by wy of the restriction orifice (2). This forces the min vlve to close further n reuce outlet pressure. When outlet pressure flls below the set pressure: The pilot vlve opens wier thn the pssge presente by the restriction orifice, enbling more wter to exit the vlve control chmber vi the pilot thn cn enter by wy of the restriction orifice, relesing pressure from the control chmber. This cuses the min vlve to open wier n thus increse outlet pressure. The restriction orifice lso controls the vlve s closing spee. For vlves 8 n lrger n justble neele vlve is provie.

Upon relese of pressure from the control chmber the vlve opens. Uner NORMAL Moel conitions, 400E wter pressure 4DCis supplie to the control chmber vi the priming line [2] n is trppe in the control chmber by rely vlve (URV-M) [7] tht is hel in the supply position by hyrulic pressure supplie through three-wy solenoi vlve [8]. Uner FIRE with conitions, Mnul wter pressure Reset is relese from the control chmber, either with the mnul emergency relese [6], or by the URV-M switching to the relese position in response to the solenoi vlve being ctivte. This ltches the 400Y eluge vlve open, llowing wter to flow into the system piping. lectriclly Pressure Controlle Deluge Vlve Sequence of Opertion Combine - Deluge/Pressure Control The BERMAD 400Y Torrent vlve is vilble in lrge vriety of eluge moels/configurtions with or without pressure control.

Uner FIRE conitions (Fig 3b), wter pressure is relese from the control chmber, either with the mnul emergency relese, or by the URV opening utomticlly in response to ecrese in pneumtic pilot-line pressure.

8 FP 400Y Instlltion, Opertion & Mintnence The correct opertion of the BERMAD 400Y Deluge Vlves epens upon instlltion in ccornce with the pprove trim configurtion. The 400Y vlve must be trimme with the correct trim components n ccessories, n must be instlle n mintine in complince with the most recent BERMAD publictions. Any evition in trim size or rrngement my versely ffect the correct opertion of the eluge vlve. Wrning: The eluge vlve n trim must be instlle in res where they re not subjecte to freezing tempertures. Instlltion Instructions 1. Allow enough room roun the vlve ssembly for ny justments n future mintennce. 2. Before the vlve is instlle, flush the pipeline to remove ny irt, scle, ebris, etc. 3. Instll the vlve in the pipeline with vlve flow rrow on the boy pointing in the flow irection. 4. Ensure tht ll other components re positione correctly s per the pproprite rwing. 5. The wter supply priming line must be connecte to the upstrem of the system control vlve. 6. All itionl ccessories, lthough not pcke together with the BERMAD Deluge Vlve, must be instlle s shown in the relevnt rwing n other illustrtions. 7. After instlltion in the min line, crefully inspect/correct ny mge ccessories, piping, tubing, or fittings; ensure tht there re no leks. Swivel flnge mounte rin vlves justment The rin vlves on most Torrent 400Y moels hve 360 swivel cpbility To position the rin vlves, loosen the 3 bolts on the rin flnge just enough so s to llow the rins to be positione to the most suitble irection for the prticulr instlltion. When the position is estblishe, retighten the rin flnge bolts. For vlves 1½ & 2 the rin vlves re ¾ i For vlves 2½ & 3 the rin vlves re 1½ i For vlves lrger thn 3 the rin vlves re 2 i Plcing in Service/Resetting The eluge vlve n the control trim shll be plce in service in ccornce to the most recent IOM mnul. After ll relevnt instructions hve been performe, slowly open the supply-isolting vlve n check tht no wter flows into the system ownstrem of the BERMAD eluge vlve. Mintennce Fig 6 : Swivel flnge mounte rin vlves BERMAD Torrent Deluge Vlves require no routine lubriction, pcking or tightening WARNING: Do not turn off the wter supply to mke repirs without plcing roving fire ptrol in the re covere by the system. The ptrol shoul continue until the system is bck in service. Prior to turning off ny vlves or ctivting ny lrms, notify locl security gurs n the centrl lrm sttion, so tht flse lrm will not be rise.
