Pneumatic valves and accessories are used for controlling air and water in multiple settings.
Normally open, single seated, straight-through or angle globe valve, for proportional control of steam/hot water in unit ventilator applications. Replacements are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.
Single-seated, straight-through, pneumatic valves used for proportional control of unit air conditioners using hot and/or chilled water. Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.
Two-position, three-way, pneumatic air valve used to control main airflow in large Day-Nite or Summer-Winter pneumatic control systems. Replacement device is available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.
Three-pipe, sequencing, pneumatically operated water valve for controlling both hot and cold water flow in fan-coil and induction units. Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.
Normally-open, single-seated pneumatic radiator valve, with straight through or angle body construction provides proportional control of two-pipe, hot water or steam systems. Replacement devices are available for most models.
Three-way pneumatic mixing valve provides proportional control of hot and/or cold water in unit air conditioners and fan coil systems. Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.
Normally open, single-seated, high pressure valve, provides proportional control of hot/cold water in air conditioner and fan coil units. Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.
Normally-open, single-seated valve provides proportional control of steam or hot or cold water in terminal units. Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.
