A.R.I. D-070P Q

Dynamic Combination Air and Pressure Relief Valve

A.R.I. D-070P Q is a Dynamic Combination Air and Pressure Relief Valve, combining two solutions in one, for maximum line protection. The Pressure Relief component allows quick- release of excessive line pressure while maintaining safe, gradual closing. When pressure rises above the set point, water is released from the valve outlet. The D-070P Q Valve prevents up-surge by discharging air from pressurized water lines in a gradual, controlled manner. When vacuum occurs, the valve emits air into the system to prevent impending down-surge. This solution protects the pipeline from excessive pressure, eliminating bursts and water loss.

Features and Benefits

Unique 2-in-1 Combination Air Valve and Pressure Relief

High-capacity air release and pressure relief for maximum system protection

System protection mechanism

Reduces local water hammer impact, saves energy and increases system efficiency

Pilot-operated valve

Continuously senses upstream pressure while also operating as a two-stage pressure relief valve

Rolling diaphragm

Normally closed air & vacuum orifice prevents the intrusion of debris and contaminants into the system

Construction materials

Non-corrosive and durable

Dynamic combination air valve

Allows smooth, gradual valve closure unaffected by water flow, discharging all air from the system
