AIR VENTS, PRESSURE RELIEF VALVES, ETC.
AA-6 Pressure Relief Valve
Uses
This moderately priced valve is especially suitable for most aluminum
sprinkler and higher pressure plastic pipe.
Features
Dependable, time-proven design with the spring on top, out of the flow,
for longer, more accurate operation. Constructed from high strength aluminum
castings with stainless steel shaft, tempered steel spring, and non-sticking
Teflon seal and bushing. This valve may be ordered factory set and sealed
under actual hydrostatic conditions, or can be shipped to you for final
field adjustment. When ordering field adjustable units, be sure to specify
pressure range as Waterman uses springs with different compressive strengths
to maximize the amount of release when excessive pressures occur.
