The 1 ½'' hydraulic drain safety valve is especially indicated for installation in the drain outlet of an automatic selector valve of a pool sand filter.

Its use prevents water losses when the valve changes its working position and in the event that the electrical power fails and the valve is left in a position in which the pool could be emptied.

Technical characteristics:

- Two connection options: double Ø50 smooth sleeve and double 1 ½" threaded sleeve.

- Working pressure range: 0.2 to 3 kg/cm2.

- Flow range: between 0.5 m3/h and 14 m3/h.

Electrical characteristics of the solenoid:

- Voltage: 24 Vac.

- Consumption: 0.125 A.

Working principle:

This is a hydraulically operated valve in which an elastic membrane closes the passage of water. The larger section existing in the upper chamber with respect to the fluid passage section causes the valve to remain closed when there is fluid pressure upstream, since the 3-way solenoid communicates the pressure from the pump with the upper chamber of the valve. valve. When opening the drain of the upper chamber, either automatically with a signal from the selector valve or by means of the manual selector of the solenoid, fluid access is not allowed to it and therefore the fluid in the line overcomes the membrane , causing the valve to open.

5 Stars. There are 5 of us and we are very happy with the hot water. After searching for information for almost a month on low-consumption hot water systems, we decided on b. heat only hot water. Delivery in just 3 days from the web order.

Delivery was delayed a day due to the height of the package but then everything was perfect.

Thank you :)
