Bistable Valve

Main Characteristics

  • Reduced size.
  • Flow rate at 3 bar: >=800 l/h
  • External leakage: <0.5 gr/year of refrigerant.
  • Internal leakage at 3 bar: < 3 l/h (tested with air).
  • Operating pressure range: from 0 to 16 bar.
  • Max. fluid temperature: 80°C.
  • Operating temperature range: -20 °C to +60 °C.
  • Voltage: 230 V (120 V available on request).
  • Low power consumption.
  • Compatible with gas R134a and R600.
  • Limited noise during operations.




Water Valves


The refrigerator solenoid valve is a device which control water flow for ice maker and drink dispenser. Based on actual product range Bitron developed a suitable valve family with close flow tolerance and low noise optimizing costs in respect to those present in the market. Extend to refrigerator valve the use of standard flowmeter to measure the exact water quantity.
Inlet and outlet to be designed according to customer needs.


Solenoid Valve with Flowmeter


Axial flowmeter can be integrate into the valve. In case of in the integration in the inlet, the total dimension of the valve remain unchanged and the flowmeter can measure the water through each outlet.

Technical characteristics

Medium temperature and water quantity:

  • 250 m3 @ 95°C
  • 450 m3 @ 65°C
  • 800 m3 @ 25°C





Systems of safety valves

We manufacture several types of safety valve. Known also aquastop, are special valves to be connected directly to the tap.


A coaxial hose collects the possible leakage into the machine. A floater / sensor detects water on the floor. Similar valves can also be mounted into the machine, without the coaxial hose.












Self Protecting Hose

Water flows in the main hose, the central magnets are in the  “open” position (both magnets are close together). The spring force is less than the magnetic force that keep in position the two magnets.

The hydrophobic membrane, is a filter for the temperature difference in order not to activate the valve unproperly.
When a leakage happens in the load hose, the water comes inside the protection hose.
This will increase the air pressure  that activate the trigger circuit (min. 40 mbar) and disjoining the magnets: this will cause the movement of the nucleous thanks to the spring.
Now the valve is closed. The water flow is interrupted.


  • Ambient temperature:  5-60°C
  • Water temperature:  Cold water: 25°C - Hot water: 90°C
  • Operating pressure:  0.2-10 bar
  • Flow rate: depending on the connected appliance
  • Flow regulator: Optional
  • Burst resistance: >31.5 bar at the specified temperature
