The hydraulic safety valve for 1 ½'' drain is especially suitable for installation in the drain outlet of an automatic selector valve of a pool sand filter.
Its use prevents water loss when the valve changes its working position and in the event of a power failure and the valve is left in a position where the pool could be emptied.
Technical characteristics:
- Two connection options: double smooth sleeve Ø50 and double threaded sleeve 1 ½".
- Working pressure range: 0.2 to 3 kg/cm2.
- Flow rate range: between 0.5 m3/h and 14 m3/h.
Electrical characteristics of the solenoid:
- Voltage: 24 Vac.
- Consumption: 0.125 A.
Operating principle:
This is a hydraulically operated valve in which an elastic diaphragm seals off the water flow. The larger cross-section of the upper chamber compared to the fluid flow section causes the valve to remain closed when there is upstream fluid pressure, as the 3-way solenoid communicates the pressure from the pump to the valve's upper chamber. When the upper chamber drain is opened, either automatically with a signal from the selector valve or using the solenoid's manual selector, fluid access is prevented, and therefore the fluid in the line overcomes the diaphragm, causing the valve to open.
