CRP-9 Continuous Acting Air Vent & Vacuum Relief Valve

The CRP-9 Continuous Acting, Combination Air Vent and Vacuum Relief Valve is designed for use on both high and low head irrigation systems. Model CRP-9 is especially suited for drip, fogger, and other low volume installations due to its high sensitivity, even at low pressures. The use of PVC allows the CRP-9 to be used where corrosive chemicals or additives are present. The continuous acting CRP-9 air vent has a minimum seating pressure of under 4 psi, and will continuously bleed air up to 100 psi. The CRP-9 is manufactured to full rated capacity. There are no restrictions reducing air passage to less than the nominal size.
