Solenoid Valves

The solenoid valve is a device which controls the flow of water into a system. The main application for this series of solenoid valves is on dishwashers and washing machines, both domestic and professional. Other typical applications include drinks dispenser, medical equipment and any appliance which uses water. It is an indirect valve, operated by a electromagnetic actuator. The valve body has a threaded inlet (normally 3/4" gas) and one or more outlets suitable for the connection of rubber hoses.

Standards

Solenoid Valve with Flowmeter

Description

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 - SPH

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.
