Two materials
Plastic VQ for landscape budgets, brass VQ75S/VQ100S for heavy public use.
One key everywhere
Coupling keys are cross-compatible within each size – standard practice for crews.
Vent automatically
VP valves release collected air at system high points without maintenance.
Protects the pump
Proper venting prevents air-lock and surge in the mainline.
Frequently asked questions
Where do air release valves go?
At high points of the mainline and above the pump manifold, per standard hydraulic practice.
