PRODUCT DESCRIPTION Viking Flow Control Valves are quick opening, differential diaphragm flood valves with a spring loaded floating clapper. The Viking Model H-2 Halar Coated Flow Control Valve is identical to the Viking Model H-1 Flow Control Valve, except the Model H-2 is manufactured with specially coated components. The body and cover of the Model H-2 Flow Control Valve is coated inside and outside with Halar Coating consisting of ethylene chlorotrifluoroethylene (ECTFE). The coating makes the valve suitable for use in corrosive environments similar to those found on offshore platforms and many industrial chemical facilities. Coatings on internal operating parts of the valve also include Teflon, Electroless Nickel plating, and Tin plating. The Halar Coated valve may be used to facilitate manual or automatic on/off control. It can also be used to control water pressure or flow rates. As an on/off control valve it is used on Deluge Systems, Sprinkler Systems or to automatically fill tanks or reservoirs. The Halar Coated Flow Control Valve can be used as a pressure reducing valve to limit or conserve water flow. 4. Viking Halar Coated Flow Control Valve: Listings and Approvals: U.L. & F.M.

2 Flow Control 504 b August 19, 2003 CESSORY package and the fittings and nipples shown on the H-1 Flow Control Valve Trim Charts. (See Table 2) Systems with water working pressures above 175 PSI (1 207 kpa) may require extra-heavypattern fittings. Viking Model H-2 Flow Control Valve flanges are Ductile Iron ANSI B16.42 Class 150 with a maximum water working pressure of 250 PSI. ANSI B16.42 Class 150 flanges are NOT compatible with ANSI Class 250 or Class 300 flanges. To mate the Model H-2 Flow Control Valve with ANSI Class 250 or Class 300 flanges, use the grooved-outlet style valve, installed with listed grooved/flange adapters of the appropriate pressure rating. For piping with grooved connections, the grooved-outlet style valve may be installed with listed grooved couplings of the appropriate pressure rating. 2. A special trim package is available for use when the Halar Coated Flow Control Valve is used as a FOAM CONCENTRATE CONTROL VALVE for AFFF or ATC Foam Concentrate. See the Viking Foam Engineering and Design Data book. Additional accessories are available and may be required for system operation or supervision. Refer to the system description and technical data for complete operating trim requirements for the system used. 6. OPERATION (RefertoFigure2) Note: For OPERATION of the Halar Coated Flow Control Valve used as a Foam Concentrate Control Valve, refer to the Viking Foam Engineering and Design Data book. The Model H-1 Flow Control valve has an inlet chamber, an outlet chamber, and a priming chamber. The inlet chamber and outlet chamber are separated from the priming chamber by the clapper (6) and diaphragm (2). System pressure enters the priming chamber through a restricted priming line (trim) equipped with a check valve. In the SET position: System pressure is trapped in the priming chamber to hold clapper (6) on seat (9) due to area differential of the clapper, and spring (11) pressure. Clapper (6) separates the inlet from from the outlet, keeping the system piping dry. In fire conditions: When the release system operates, pressure is released from the priming chamber faster than it is supplied through the restricted priming line. Water supply pressure in the inlet chamber forces the clapper (6) off from seat (9) allowing water to flow through the outlet and into the system piping and alarm devices. 7. AVAILABILITY AND SERVICE The Halar Coated Viking Flow Control Valve and accessories are available through a network of Domestic, Canadian, and International Distributors. See the Viking Corp.

Check with manufacturer prior to using this valve with fluids other than fresh water and those listed in Table When the Halar coated Flow Control valve is supplied with anything other than clean fresh water, such as salt water or brackish water, conventional trim should not be utilized. Stainless steel or brass trim should be used for those installations. 4. Use caution when using wrenches on or around Halar Coated Valves. Halar Coating may chip when struck with hard or sharp objects. If the Halar coating becomes chipped, immediately repair the damaged area to inhibit the potential for corrosion. Refer to paragraph 12 REPAIR and Halar Coating Repair instructions. 5. Halar Coating is black in color. Due to its chemical resistance paint will not adhere to Halar Coating sufficiently to resist abrasion. 6. The valve must be installed in an area not subject to freezing temperatures or physical damage. 7. The valve must be trimmed according to current Viking Model H Conventional Trim Charts and appropriate instructions for the system used. Trim Charts are printed in the Viking Engineering and Design Data book, and are provided with trim packages. For additional trim connections, refer to technical data describing the system being installed. 8. The priming line must be connected upstream of the system water supply main control valve or to a constant source of water at a pressure equal to the system water supply. 9. After the Flow Control Valve is set, operation of the Flow Control Valve requires the release of priming water from the priming chamber. This may be by automatic or manual operation of the release system. Viking Flow Control Valves are compatible with hydraulic, pneumatic, and electric release systems. For specific Trim arrangements, refer to Trim Charts, Technical Data, and System Data describing the system being installed. Trim Charts are printed in the Viking Engineering and Design Data book and are provided with trim packages. Technical Data and System Data sheets are printed in the Viking Engineering and Design Data book. a: Hydraulic Release Systems: See Graphs A through C (pages 504 h and i) for the maximum allowable elevation of hydraulic release piping above the Flow Control Valve. If the maximum height of hydraulic release piping exceeds the limit shown in Graph A, B, or C for the valve used, use a Pneumatic or Electric Release System. b: Pneumatic Release Systems: A Viking Pneumatic Actuator is required between the release system connection provided on flow Control Trim and pneumatic release system piping. Caution: When releasing devices capable of automatically resetting are used on the pneumatic release system of a Flow Control Valve, Viking Model E Deluge Valve Conventional Trim, complete with PORV, is required. This arrangement will not allow the Flow Control Valve to automatically reset. c: Electric Release: Solenoid Valves, Release Control Panels, and Electrical Detectors must be compatible. Consult appropriate listing and/or approval guides. 10. The Viking Flow Control Valve can be trimmed to automatically reset electrically or manually. For specific Trim arrangements refer to System Data describing the system being installed. Note: Do NOT install any releasing device, or valve used to automatically reset the Flow Control Valve, on pneumatic release piping. For pneumatic release systems, any releasing valve or device used to automatically reset the Flow Control Valve must be installed in the trim piping between the Pneumatic Actuator and the priming chamber outlet. Caution: Operation of Viking Flow Control Valves by pressurizing the priming chamber with air or any other pressurized gas is not recommended or approved. 9-B.
