DESIGN The valve shall be a single-seated, line pressure operated, diaphragm actuated, pilot controlled globe or angle valve. The valve shall seal by means of a corrosion-resistant seat and resilient, rectangular seat disc. These and other parts shall be replaceable without removing the valve from the line. The stem of the main valve shall be guided top and bottom by integral bushings. Alignment of the body, bonnet and diaphragm assembly shall be by precision dowel pins. The diaphragm shall not be used as a seating surface, nor shall pistons be used as an operating means. The pilot system shall be furnished complete and installed on the main valve, and shall include an opening speed control and a Y-strainer. The valve shall be operationally and hydrostatically tested prior to shipment. MATERIALS OF CONSTRUCTION The main valve body and bonnet shall be ductile iron per ASTM A536, Grade 65-45-12 (or other materials refer to MATERIALS). All internal ferrous surfaces shall be coated with 4 mils of epoxy. External surfaces shall be coated with 4 mils of epoxy followed by a coat of enamel paint. The main valve seat ring shall be bronze per ASTM B61 (or other materials refer to MATERIALS) . Elastomers (diaphragms, resilient seats, and O-rings) shall be Buna-N. Control pilot shall be ASTM B61 bronze (or other materials refer to MATERIALS). The opening speed control shall be brass/stainless steel and control line tubing shall be copper (or other materials refer to MATERIALS). OPERATING CONDITIONS The fire pump suction control valves shall be suitable for sustaining suction pressures of 5 - 30 psi. ACCEPTABLE PRODUCTS The fire pump suction pressure control valve shall be a Model 108FPS, Factory Mutual Approved, (globe pattern, angle pattern), with (150# flanged, 300# flanged) end connections, as manufactured by OCV Control Valves, Tulsa, OK, USA.

For maximum efficiency, the OCV control valve should be mounted in a piping system so that the valve bonnet (cover) is in the top position. Other positions are acceptable but may not allow the valve to function to its fullest and safest potential. In particular, please consult the factory before installing 8" and larger valves, or any valves with a limit switch, in positions other than described. Space should be taken into consideration when mounting valves and their pilot systems. A routine inspection & maintenance program should be established and conducted yearly by a qualified technician.
