Water Flow Switch WFS Series
Honeywell provides WFS series water flow switches which have been designed to provide excellent performance where accuracy, reliability, and rugged construction are required. These flow switches are used in liquid flow lines carrying water or any fluid neither harmful to brass and phosphor bronze nor classified as a hazardous fluids. They can be wired to close one circuit and open a second circuit when liquid flow either exceeds or drops below the adjusted flow rate. The WFS series are recommended for liquid pressure and temperature as mentioned below and must not be used on lines carrying liquids below 0C.
Features & Benefits:
- These series may be used on liquids with high salt or chlorine content
- They may be also used outdoors
- They are designed for use only as operating controls

Micro Switch BZC SeriesValve Actuator ML 7421 Series
The ML6421A,B Non-Spring Return Electric Linear Valve Actuators are suitable for use with low-voltage, single-pole double-throw (spdt), Series 60 two-position and floating controllers. These actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications. The ML7421A,B Non-Spring Return Electric Linear Valve Actuators are modulating control actuators used with controls that provide an analog output of 0 to 10 Vdc or 2 to 10 Vdc. These actuators operate standard Honeywell valves in HVAC applications. An internal selector plug can be used to reverse the direction of action.

Motorized Valve VC Series
Honeywell VC Series balanced 2-position hydronic valves are used in domestic and small commercial heating and cooling applications to control the flow of hot and/or cold water. They consist of an actuator, valve and a cartridge assembly 2-way valves are designed for on-off zone control of domestic systems. 3-way valves can be piped for either diverting or mixing valve applications in domestic central heating and/or cooling systems. Both versions can be used to control indi-vidual fan coil, radiator, space heater or convector applica-tions. Depending on the model selected they can be con-trolled by a low or line voltage SPST or SPDT controller such as a room thermostat, aquastat or flow switch.
