GA Figure 5670 Pressure Relief/Sustaining Valve, Series 5000 Diaphragm Operated

Sizes 1¼” to 16”

Productgroup: Surge Relief Valves

Medium: Water

GA industries Series 5000 are pilot-operated, diaphragm actuated water control valves.  The GA Figure 5670 valve can be used in either of two applications:

Pressure Relief: installed on the side outlet of a tee and closed under normal pressure conditions. The valve opens upon a rise in pressure above normal to discharge water out of the system to safely limit the pressure increase 

Pressure Sustaining: installed in the main run, opens to allow flow into downstream system when inlet pressure exceeds minimum, throttles as needed to sustain minimum inlet pressure, closes if inlet pressure falls below minimum

Standard features include pilot wye-strainer and isolating valves and inlet pressure gauge. Many optional features and accessories are available.

The valve is available with full port globe body up to 16” size or reduced port globe in 3” to 10” sizes, NPT connections to 3” and Class 150 or 300 flanged from 2” to 16”.  Full port angle body valves are available 1¼” to 10”.
