Kingston air powered, valve actuators are designed for use with selected Kingston valves where remote control is desirable. The actuator/valve combination is well suited for use in areas where explosive gases may be present. They are an effective alternative to the high priced, explosion-proof, electrically operated valve. Maximum recommended operation temperature, 250°F.

Figure 329-l - Actuator is used with the Kingston Fig. 305A and 305B in I/4" and 318"; Fig. 425, l/4"; and the *Fig. 375, normally closed valve, in l/4," 3/8" and l/2" sizes. Mounting thread, 5/8"-18. Maximum pressure to actuator, 125 PSIG.

Figure 331-2 - Actuator is used with the Kingston Fig. 305A, 305B and 425, t/2" through I-114" sizes. Mounting thread,  3/4"-16.

Maximum actuator pressure, 100 PSIG.

Figure 305A available in sizes l/4" through l-114". For air and liquid service. See Bulletin 103 for detail.

Figure 305B, available in l/4" through l-114". Balanced valve for air and liquid service. Best selection when actuator air pressure is low.

Figure 425, available in l/4", l/2", 3/4", 1" and l-114" sizes. For steam service. See Bulletin 101A for detail.

*Fig. 375 valves are designed for normally open operation. Contact factory for additional information.
