Zone Valves
The Schneider Electric Modulating PopTop™ Series valve actuator assemblies are designed for closed hydronic heating and cooling systems. The Modulating PopTop is used to control fluid flow in fan coil units, VAV reheat, unit ventilators, AHUs and radiant applications. The Modulating PopTop Proportional (P) type is compatible...
PopTop Series valve bodies and actuators provide easy installation for a variety of heating and cooling applications. Valve’s actuator can be installed after valve body has been installed onto fan coil, baseboard or air handler. VS Series valves are available for low pressure steam applications.
The SSA/SSP Electronic Valve Actuator requires a 24 Vac power supply and receives a 0 to 10 Vdc signal or a floating control signal to control a valve. This actuator is designed to work with Zone Control Valves with a 1/10- inch (2.5 mm) stroke and a threaded valve bonnet that fits the actuator.
The SFA/SFP Series of Electronic Valve Actuators accepts 24 Vac or 120 Vac power supply signal to provide two-position control. This actuator works with Zone Valves with 1/10-inch (2.5 mm) stroke.
Two- and Three-Way Zone Valves have a 1/10-inch (2.5 mm) stroke. The Zone Valves work with any SFA/SFP Series, SSA/SSP Series electric actuator, or with the STA/STP Series Thermic actuator. The actuators accept one of either 24 Vac or 120 Vac power supply signal to provide on/off, floating or 0 to10 Vdc control.
On-off and diverting low voltage valves consist of an actuator and valve assembly for controlling the flow of hot water.
Two-way on-off low voltage valves consist of an actuator and valve assembly for controlling the flow of hot water.
On-off and diverting line voltage valves consist of an actuator motor and valve assembly for controlling the flow of hot or chilled water.
Two way on-off line voltage valves consist of an actuator motor and valve assembly for controlling the flow of low pressure steam.
Two way on-off line voltage valves consist of an actuator motor and valve assembly for controlling the flow of hot or chilled water.
Honeywell MZV Series is the first linear zone valve with a built-in balancing plug that permits pre-balancing for each zone.
Control central heating and/or cooling systems, fan coil systems, radiators and convectors. Depending on the model selected, it can be controlled by either a low or line voltage SPST or SPDT or floating controller such as a room thermostat, Aquastat control, or flow switch.
