General
The DIASTAR 10 and 16 valves from GF Piping Systems incorporate several innovative features. The valve has Cv values
that average at least double the conventional design. This high-flow design allows the valve to be used where diaphragm
valves were previously not possible due to flow restriction. In addition, the new design eliminates the four bolts used to
hold the valve together, which eliminates a corrosive weak point. The valve is available in PVC, CPVC, PP, PP-n, and PVDF.
The DIASTAR 10 is designed to handle pressures up to 150 PSI and the DIASTAR 16 can handle up to 240 PSI. A modular
design allows easy field installation of an actuator to a manual valve as well as other accessories such as position feedback
switches.
