Bulletin 618 January 2018 Reliable Model TD Test and Drain Valve cULus Listed,FM Approved 300 psi(20.7 bar)pressure rated Product Description The Reliable Model TD Test and Drain Valve is a single-han dle,tri-position ball valve allowing both testing of the waterflow alarm and draining of a wet-pipe fire protection system. The valves are cULus Listed and FM Approved. The Model TD Valve has a pressure rating of 300 psi(20.7 bar). W f r{ sol Model TD Test and Drain Valves have a restricted orifice with • the available K-factors listed in Table A. Nominal Valve Sizes are 1", 1 1/4", or 2" with either NPT or IS07-1 end connections. Table C identifies the materials used in the Model TD valve. Model TD Test&Drain Valve 1"with optional relief valve kit The Model TD valve is available with an optional relief valve kit. The relief valve kit includes a Reliable Model A relief valve along with a hose and all fittings needed to connect the relief valve to the Model TD valve. The Model A relief valve is UL Listed and FM Approved for use on fire protection systems. The Model A relief valve is available with a nominal pressure rating of 175 psi (12 bar), 185 psi (13 bar), 210 psi (14 bar), 260 psi (18A + _� a aar),or 310 psi(21 bar). See Reliable Technical Bulletin 257 for dditional information on the Model A relief valve. An optional mocking handle kit is available for use with customer supplied padlocks. Installation Model TD Test& Drain Valve 1 1/4"with optional relief valve kit Connect the "IN" port of the Model TD valve to the wet-pipe sprinkler system. Connect the "OUT" port to a properly sized drain, The optional relief valve kit is installed as shown in the photo- graphs in this bulletin after removing the plugs in the cap and ` body of the Model TD valve. The relief valve is commonly in _ � � stalled after hydrostatic testing. Operation To run a test,rotate the handle counter-clockwise until the"Test" Model TD Test&Drain Valve 2"with optional relief valve kit position is aligned with the ball detent. Note that rotating the valve to the "test" position is intended to operate the sprinkler system's waterflow alarm. To drain, rotate the handle further until the "Drain" position is aligned with the ball detent. Return the handle to the "Off" position when all testing and draining functions have been completed.
