Zoning Control Systems

BI-TORQ 115VAC electric actuators have a standard NEMA 4 enclosure, 25% duty cycle motor, thermal overload protection and on-off limit switches. ISO mounting for direct mount of ISO ball or butterfly valves.

The PN series pneumatic actuator has an anodized aluminum body and meets international ISO and NAMUR standards for ease in mounting to ISO valves. Double acting actuators are air to open, air to close and are sized for 80 PSI air supply. Standard actuators are rated to 180°F with options for high temperature Viton seals. The PN-63-DA has 586 inch pounds output torque at 80 PSI air supply.

The PN series pneumatic actuator has an anodized aluminum body and meets international ISO and NAMUR standards for ease in mounting to ISO valves. Spring return actuators are air to open, spring to fail close and are sized for 80 PSI air supply. Standard actuators are rated to 180°F with options for high temperature Viton seals.

The BI-SS series pneumatic actuator has an all-stainless steel body for tough environments, the food industry, or pharmaceutical applications. The actuator meets international ISO and NAMUR standards for ease in mounting to ISO valves. Spring return actuators are air to open, spring to fail close and are sized for 80 PSI air supply. Standard actuators are rated to 180°F with options for high temperature Viton seals. The BI-60-SS-SR actuator puts out 135 inch pounds of spring end torque at 80 PSI supply pressure.

MV air switches are 3-way 1/8" ported air pilot valves that are identical in size, actuating style, and mounting characteristics to most industrial type electric limit switches. Use them in place of electric limits to save on hookup cost and eliminate spark hazard. MV valves simplify circuits by eliminating the need for wire shielding, transformers, and solenoids. The MV air switch may be piped normally closed, normally open, or as a diverter.
