Electric Valve ActuatorsBall- and globe-valve actuators designed to provide precise floating / incremental control of valves in HVAC applications. Feature a synchronous motor to deliver running torque of up to 675 inch lb(59 Products)
Globe Valves Less ActuatorJohnson Controls globe valves less actuators regulate the flow of hot or cold water in small HVAC terminal units, like fans or reheat coils. They are offered in NO (normally open) and NC (normally closed) configurations.(117 Products)
Low Voltage ThermostatsDesigned for controlling multi-stage heating and cooling equipment, such as rooftop or self-contained units equipped with a humidifier and / or dehumidifier. Powered by a transformer which decreases the incoming line voltage from 120 V down to a level ranging between 12 and 24 V(20 Products)
Thermostat GuardsUsed to protect thermostats and humidistats from damage, vandalism, tampering and unauthorized adjustment. 304 stainless-steel thermostat guards offer longevity and durability, even in humid or corrosive environments. Also, available in plastic, cast aluminum and wire construction variants(10 Products)
Oil Protection ControlsProvides dependable protection to pressure-lubricated refrigeration compressors against major breakdowns caused by low lubrication oil pressure. Features a built-in time delay switch with a universal mounting bracket(15 Products)
Pneumatic ControlsManage the flow in HVAC systems by using air as a control medium to stop or change the flow direction. Dependable pneumatic damper actuators provide proportional control of the dampers in independent or sequence configuration. Essentially require no maintenance except for inspection and adjustment(80 Products)
Single Pressure ControlsJohnson Controls single pressure controls regulate & protect high / low pressure compressors in HVAC systems while preventing loss of refrigerants.(71 Products)
Building Automation ControlsJohnson Controls building automation controls include humidity sensors & transmitters, line-voltage thermostats, zone controllers and installation accessories, such as battery packs & antennas for detecting the real-time status of the environmental parameters in HVAC applications.(17 Products)
Head Pressure ControlsJohnson Controls head pressure controls include condenser fan speed controls, pressure transducers and software suitable for condenser fans to configure fan speeds and head pressures.(20 Products)
Boiler ControlsJohnson Controls boiler controls like pressure controls are suitable for steam, water, air or non-combustible gases. They feature a self-opening / closing mechanism with the slightest change in pressure.(2 Products)
Pneumatic ControllersDesigned to measure the temperature and pressure, as well as transmit a corrective air signal to the final control element. Operate using a coordination of thermal or pressure sensing system and an air signal relay system(7 Products)
Humidity ControlsJohnson Controls humidity controls, such as humidistats & humidity stage modules, are used to reduce the excessive relative humidity in fruit storage rooms, curing rooms and electrically-heated spaces.(3 Products)
Damper and Valve Replacement MotorsJohnson Controls damper and valve replacement motors are used to adjust the flow of air in HVAC systems. Direct-mount actuators detect On / Off, proportional and floating input signals over valves & dampers in semiconductor fabrications or machine tooling jobs.(76 Products)
Pneumatic RelaysPrecision relay devices designed to operate pneumatic valve actuators in applications requiring a stable, accurate control. Compensate for flow surges in the piping system and hold the valve at the position dictated by the controller. Allow easy valve sequencing from a single control signal(2 Products)
Current Sensor RelaysNormally open relays designed to provide adjustable trip-current facilities on pumps, driving fans, blowers & heating coils. Can sense a maximum current overload value of 200 A(1 Product)
Duct Pressure SwitchesJohnson Controls duct pressure switches use differential air pressure to actuate electric switches at a pre-set actuation point. They are used to sense airflow in ducts. When used with electric strip heaters, they can open the circuit or de-energise the heaters as the airflow stops.(12 Products)
