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

  • EMC: fully compliant
  • Approvals: European standard EN 60730-1, EN 60730-2-8. On request UL/CSA
  • Potable water approvals: WRAS. On request NSF, FDA
  • This product meet the requirement of the European Directive 2002/95/CE on RoHS

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.

TECHNICAL DATA

  • 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

Motorized Valves For Alternating Washing

Main Features

Two standard drive systems are available: they are made by a motor gear train, coding contacts and output pignon. They may be adapted to different valve configurations, as shown in the photos.


motorized-valves

Through-flow Heater With Motorized Valve

Main Features

The motorized valve is used to divert the water flow between the upper and lower spray arm in order to optimize the pump performance and reduce water and energy consumption allowing a smooth transition from upper to lower spray arms.
Operating modes:

  • Alternating between upper and lower spray arms.
  • Washing with upper spray arm only
  • Washing with lower spray arm only
  • Washing with both spray arms

Contact for position identification
Reduced pressure drop.
