Metering Ball Valve with EPDM Seals for Cold Water & Soaps – Series 523

The Series 523 Ball Valves are metering ball valves made out of PVC, CPVC or PP (choose your size & material above) for low pressure systems.
They come standard with stainless steel threaded inserts for easier and more secure mounting.
For chemical resistant FPM sealed metering ball valves please see GF523-FPM.

An integrated index plate shows the stoke in degrees with an indicator arrow, attached to the valve handle. The plate also shows correct flow direction with the indicator arrow.
The V-notch design helps to have much better control of the flow compared to 90 degrees V-notches – even at low flow amount.
