TFP102O Page 4 of 20 Technical Data Approvals ILL and C-UL Listed. FM Approved. NYC under MEA 172-02-E (4 and 6 inch). Dry Pipe Valve The TYCO Model DPV-1 Dry Pipe Valves are for vertical installations (flow going up), and they are rated for use at a maximum service pressure of 250 psi (17,2 bar). The Valve dimensions are shown in Figure 7. Flanged connections are available and drilled per ANSI, ISO, AS, and JIS spec- ifications (Ref. Table A). The grooved outlet connections, as applicable, are cut in accordance with standard groove specifications for steel pipe. They are suitable for use with grooved end pipe couplings that are listed or approved for fire protection system service. Available combinations of inlet and outlet connections are detailed in the Ordering Procedure section. They are also noted in the "Available End Connection and Sizes" table located on Page 1. Threaded port connections of valves having flanges drilled to ANSI, AS, or JIS specifications are NPT threaded per ANSI Standard B1.20.1. Threaded port connections of valves having flanges drilled to ISO are available either threaded per ISO 7-1 or NPT threaded per ANSI Standard B1.20.1. Valves with NPT threaded ports will readily accept the trim arrangements detailed in Parts 2 and 3 of Figures 4, 5, and 6. Components of the DPV-1 Valves are shown in Figure 1. The Body and Handhole Cover are ductile iron. The Handhole Cover Gasket is neoprene, and the Clapper Facing is EPDM. The Air/Water Seat Ring is brass, the Clapper is bronze or aluminum bronze, and both the Clapper Retaining Plate and Latch are bronze. The Hinge Pin is aluminum bronze, and the fasteners for the Handhole Cover are carbon steel. Valve Trim Installation dimensions are given in Figure 7, and the Valve Trim and Pre -Trimmed Valve Assemblies are illustrated in Figures 4, 5, and 6. The Valve Trim and Pre -Trimmed Valve forms a part of the laboratory listings and approval of the DPV-1 Valve and is necessary for the proper operation of the DPV-1 Valve. Each package of trim and pre -trimmed includes the following items: • Water Supply Pressure Gauge • System Air Pressure Gauge • Air Supply Connections • Main Drain Valve • Low Body Drain Valve • Alarm Test Valve • Automatic Drain Valve • Drip Funnel • Connections For Optional Quick Opening Device (Accelerator) Also included in the Pre -Trimmed Valve Assembly, which can be ordered sepa- rately for the Valve Trim, includes the following items: • Model BFV-N butterfly vlave • Figure 577 grooved coupling • PS10-2 waterflow alarm switch • PS40-2 low air pressure alarm switch Note: When the system pressure is greater than 175 psi (12,1 bar), provision is to be made to replace the standard order 300 psi (20,7 bar) Water Pressure gauge with a separately ordered 600 psi (41,4 bar) Water Pressure Gauge. Air Supply Table B shows the system air pressure requirements as a function of the water supply pressure. The air (or nitrogen) pressure in the sprinkler system is recommended to be auto- matically maintained by using one of the following pressure maintenance devices, as appropriate: • Model AMD-1 Air Maintenance Device (pressure reducing type). • Model AMD-2 Air Maintenance Device (compressor control type). • Model AMD-3 Nitrogen Maintenance Device (high pressure reducing type). The Pressure Relief Valve provided with the valve trim is factory set to relieve at a pressure of approximately 45 psi (3,1 bar). If the normal system air pressure is less than or exceeds 40 psi (2,8 bar), then the pressure Relief Valve must be reset to relieve at a pressure that is in accordance with the authority having jurisdiction. Quick Opening Device As an option, the Model DPV-1 Dry Pipe Valve may be equipped with the VIZOR Electronic Dry Pipe Valve Accelerator (4 and 6 inch sizes) as detailed in Technical Data Sheet TFP1105 or the Model ACC-1 Mechanical Dry Pipe Flange Drilling Specification Nominal Dimensions in Inches and (mm) Nominal ANSI B16.1 r IS0 7005-2 JIS B 2210 AS 2129 Valve Size (Class 125) (PN16)2 (10K) (Table E) Dim.
