Philmac OptiPHIL
With a new compact arm design, the dedicated OptiPHIL Above Water valve will allow for minimal/zero air gap in above-water installations and an arm extension for even more water level flexibility.
The Smooth-Flo design optimises water flow out of the valve, reducing turbulence, minimising float bounce, cutting water spray, and saving your pump.
Patent protected, Opti-Flo technology, optimises water flow through the valve to help prevent blockages & improve performance in dirty water. While patent protected, soft closing design provides a reliable shut-off & prevents damaging water-hammer.
OptiPHIL is a full flow design, providing flows up to 847 L/min, and preventing pump short cycling, saving your pump and energy.
