Apex Xtraflow Bottom Entry Valve

Product image Price: €36.90

The Xtraflo valve is a full flow valve that allows fast tank filling and eliminates the problems of damage to the valve.

The "Xtraflo" float valve is designed to be installed on the inside of a plastic or concrete water tank. Simply screw the Xtraflo valve into the tank inlet, adjust the float cord length and that's it ! It comes complete with a plastic float and cord.

Xtraflo Trough Valve Operating Principle

The Xtraflo valve is a diaphragm operated valve, it uses the line pressure to open and close the main valve diaphragm. The standard valve has a minimum operating pressure of 55 kPa (8psi) and the low-pressure valve has a minimum operating pressure of 30 kPa (4psi).

Closed position

The water pressure in the inlet of the valve is allowed to pass up the side of the stainless spindle into the cavity in the cap.

This pressurises the area behind the diaphragm to the same pressure as the inlet of the valve.

Since the area behind the diaphragm is much greater than the inlet of the valve, the diaphragm is held against the valve seat and the valve remains closed.

Open position

As the water lever falls, the lever is allowed to drop.

This pulls the stainless spindle away from the valve inlet.

The pressure behind the diaphragm is vented through the cap.

The pathway from the inlet of the valve to the space behind the diaphragm is also closed off.

The pressure of the water in the inlet is now able to push the diaphragm off the seat, opening the valve.
