How The AKO Pressure Relief Valves work
The AKO Pressure Relief Valves are fitted onto a bypass line of a pump. The Pressure Relief Valves are then charged with air and set closed at the pressure it is required to relieve at. If the associated pump becomes clogged or blocked, causing the line pressure to exceed the pressure at which the valve is set closed at, it will open allowing the product to bypass the pump and equalise the pressure until the blockage is cleared. The Pressure Relief Valve will then reset itself in its ‘closed’ position to the original set pressure.
