PACIFIC MODEL AQUA 80-960B Direct Acting Pressure Reducing Valve Simple, Reliable and Accurate • • • • Automatic and autonomous operation Easy adjustment and maintenance Approved materials Cla-Val guarantee Operation The model AQUA 80-960B reduces a higher inlet pressure to a lower downstream pressure, regardless of upstream pressure and flow variations. The simple, and robust design of the model AQUA 80-960B allows stable operation, minimal maintenance as well an assembly in various positions. Performance and Characteristics Technical Data Sizes: DN 40 to DN 150 Pressure and flange drillings: PFA 10 bar - ISO PN 10 PFA 16 bar - ISO PN 16 PFA 25 bar - ISO PN 25 PFA 40 bar - ISO PN 40 Temperature range : 1˚- 60˚ Upstream pressure : 40 bar max. Downstream pressure : 2 to 14 bar Test : DESP 97/23/CE Leakage class : ANSI/FCI 70-2 CLASS III Q1 : Flow based on 1 bar pressure drop across the valve Q2 : Recommended flow based on 2 m/s velocity Q3 : Intermittent flow based on 4 m/s velocity Dimensions DN L [mm] H max [mm] B [mm] BB [mm] Weight [kg] 40/50 230 325 60/65 240 400 80 260 460 83 93 100 13 18 27 100 280 575 110 117.5 45 125 320 815 125 135 90 150 350 815 143 150 100 PACIFIC B : PN 10-16 / BB : PN 25 Simple, Reliable and Accurate Materials of Construction • Ductile Iron body and cover for high pressure GGG 40 epoxy coated • Stainless Steel Valve / Disc guide • Stainless Steel seat • Stainless Steel screws and bolts Item 1 2 3 5 6 7 8 11 24 25 26 Title Body Seat Disc retainer Piston Cover Spring Spring Guide Air release plug Blocking nut Adjusting tangent Gasket Material Ductile iron - GGG 40 Stainless Steel - AISI 316 Stainless steel - AISI 303/304 Bronze - ASTM B62 Ductile iron - GGG 40 Steel Stainless Steel - AISI 303/304 Stainless Steel - AISI 303/304 Stainless Steel - AISI 303/304 Stainless Steel - AISI 303/304 Caoutchouc EPDM Installation and Maintenance The pressure reducing valve is assembled as shown on the typical installation schematic. Proper mounting is indicated by the inlet plate or flow arrows. The Pressure reducing valve AQUA 80-960B can be assembled in any position. • To vent the valve use the flange air release plug (9). • Adjust downstream pressure using the cover adjusting screw (14). • Turn the adjusting screw clockwise to increase the outlet pressure, counterclockwise to decrease pressure. • Internal piston and parts can be disassembled without removing the valve body from the main line. • Upstream and downstream gate valve (1) drip tight closed. Adjusting screw Cover (with adjustment indicator) Spring Internal piston & parts Typical installation: 1) Gate valve (downstream and upstream) 2) H-Strainer, AQUA 90-501 3) Downstream pressure valve AQUA 80-960B 4) Dismantling joint 5) Air valve AQUA 70-506 visit www.cla-val.com to learn more about our complete line of Automatic Control Valves PACIFIC AQUA 80-960B Direct Acting Pressure Reducing Valve Cla-Val Model 80-960 Valve Capacity and Sizing Selection Guide: Metric Flow Units Cla-Val Model 80-960 Valve Capacity and Sizing Selection Chart Flow Rate (cubic meters/hr) 100.0 DN40/50 (2") 10.0 DN60/65 (2.5") DN80 (3") DN100 (4") DN125 (5") DN150 (6") 1.0 0.1 1.0 Differential Pressure (Bar) 10.0 Cla-Val Model 80-960 Valve Capacity and Sizing Selection Guide: English Flow Units Cla-Val Model 80-960 Valve Capacity and Sizing Selection Chart Flow Rate (gpm) 1000 100 DN40/50 (2") DN60/65 (2.5") DN80 (3") DN100 (4") DN125 (5") DN150 (6") 10 0.1 1.0 10.0 Differential Pressure (Bar) Cla-Val Model 80-960 Valve Capacity and Sizing Selection Guide: GPM versus PSID Cla-Val Model 80-960 Valve Capacity and Sizing Selection Chart Flow Rate (gpm) 1000 100 DN40/50 (2") DN60/65 (2.5") DN80 (3") DN100 (4") DN125 (5") DN150 (6") 10 1.0 10.0 100.0 Differential Pressure (psi) Port Hill Road, Level Two, Woolston, Christchurch, 8042, New Zealand • Phone: (64) 39644860 • Fax: (64) 39644876 • Website www.cla-val.com Cla-Val 2012 Printed in USA Specifications subject to change without notice.
