North American Manual and Automatic Oil Shutoff ValvesFEATURES — Normally-closed — Electrically actuated — Swinging gate body — For shutoff service OPERATION TEMPERATURE LIMITS All valves can handle fluid temperatures from -20 F (-28 C) to +250 F (+121 C). Ambient temperature limits vary. Any valve on this page using dc voltage and all V2" and 3/4" series 1517 and 1517U Valves can handle ambient temperatures from -20 F (-28 C) to +125 F (+52 C). The other valves on this page handle ambient temperatures from -20 F (-28 C) to +140 F (+60 C). All electro-mechanical valves require a constant supply of electrical energy to their holding actuator solenoids. Once the solenoid is energized, the manual reset valve may be opened manually, or the automatic reset valve will automatically open. Interruption of electrical power causes an immediate "trip" of the valve to its normally-closed position. Body Material © Sanctioned series are sold for "clean fuel oils" and carry UL, FM, and CGA sanctions. They are IRI approvable for liquefied petroleum gases, #1 and #2 fuel oils, kerosene, JP-4 and preheated #4, #5, and #6 oils with maximum viscosity of 5000 SSU. © Non-sanctioned series do not carry blanket approval/listings, and the pressure limits shown apply only for selected special service applications. An analysis of your fluid will determine the actual rating, trim, and specifics for your application. ® Maximum operating pressure differential must not exceed the maximum inlet pressure.

ELECTRICAL DATA for normally-closed valves General Shutoff valves are electrically actuated from the flame safeguard and/or safety control circuits. Standard valve assemblies include an internal holding solenoid or printed circuit board for 120 volt 60 hertz ac power. (Other electrical current options are available upon request.) 1516/1517 Valves have the internal solenoid. The solenoid (or the printed circuit board) is energized whenever the valve is powered. The motor operator on automatic reset versions is powered only during the opening stroke. Switch wiring diagrams (see page 4) are...

VALVE BODY AND TRIM Trim identification of oil shutoff valves is two-part. The first digit before the hyphen is a number (1, 2, 3 or 4) identifying body material as in Table 1 below. The second digit after the hyphen identifies trim utilizing the materials listed in Table 2. Standard sanctioned valves incorporating a cast iron body will normally be identified by 1-B or 1-D. Sanctioned valves with steel body will normally be 2-D. Non-sanctioned fuel services or unusual applications may re- quire upgrading of internal trim.
