CLEPAS pneumatic airflow differential pressure switches sense differential air pressure in HVAC systems and provide on-off output.

EPSA10 supervisory pressure switches are designed for use in wet, dry, deluge, and pre-action automatic sprinkler systems to indicate a discharge from a sprinkler.

EPSA40 supervisory pressure switches are designed for use in wet, dry, deluge, and pre-action automatic sprinkler systems to indicate a discharge from a sprinkler.

P643A1007 Pressuretrol™ pneumatic switches convert pneumatic signals from controllers to electrical switches in order to provide start and stop control.

P658 pneumatic/electric switches convert a controller's pneumatic signal to electrical switching, providing start and stop control.

RP970A pneumatic capacity relays are direct acting, proportional relays with a 1:1 pressure ratio.

SP470A pneumatic diverting switches provide a means of manually diverting air between various system components such as valves, thermostats, and damper operations in pneumatic control systems.

SP970 manual or minimum position pressure regulators are used to manually position a remote damper actuator or reset the setpoint of a pneumatic controller.

System sensor EPS120 series supervisory pressure switches are designed to supervise system air pressure in pipes or pressure tanks, as well as water or air pressure supplies of automatic water control valves.
