AKR-40605

Pneumatic 1:1 ratio direct acting relay is used to limit minimum or maximum output pressure. The AKR-40605 can also be used as a manual positioner, 1:1 ratio relay, or lowest of two pressures selector. Relay will also increase the capacity of a controller (except when used as maximum output...

AKS-1100

Setpoint adjuster and scale plates used to provide remote setpoint adjustment of RKS-2001, RKS- 4002, and RKSR-4000 receiver-controllers. May also be used to manually pilot pneumatic relays.

AL-15x Series

For applications where an electrical circuit is used to control a pneumatically operated device. Used to direct supply air to a pneumatic device when the coil is energized or de-energized depending on the supply and exhaust air connections. May be used for selection or diverting applications....

AL-161-4

Three-way air switching valve is used for central supply air changeover in dual pressure systems.

 

 

 

 

 

AL-17x Series, AL-18x Series

For applications where an electrical circuit is used to control a pneumatically-operated device. Used to direct supply air to a pneumatic device when the coil is energized or de-energized, depending on the supply and exhaust air connects.

AL-19x Series

For applications where an electrical circuit is used to control a pneumatically operated device. Used to direct supply or control air to pneumatic devices when the coil is either energized or de-energized, depending on the supply and exhaust air connections.

C-2040

The C-2040 Averaging Cumulator is a low volume output device designed to operate a controlled device or receiver-controller by averaging the output signals of two, three, or four controllers or transmitters. The Cumulator produces an output signal equal to the average of the input signals. Refer...

C-2220

The C-2220 High-Low Pressure Selector selects and transmits control pressure signals from a group of thermostats or controllers. The selector is available in either high or low volume output modules. The appropriate C-2220 module must be selected to work with either high or low volume...
