Description
The Allegro NV20-16 is a replacement adjustable flow control valve engineered to regulate breathing-air flow from a high-pressure air source into compatible Nova 3 and Nova 2000 supplied-air helmets. It provides the wearer with the ability to fine-tune the airflow to suit working conditions and personal comfort, which is especially helpful in abrasive blasting and other respirator-intensive applications.
This valve features an easy-to-turn adjustment mechanism that can be operated even while wearing thick gloves, and it delivers controlled airflow starting from the minimum required by NIOSH up through a higher, more comfortable setting. The assembly typically includes a waist belt for secure attachment and convenient use on the job.
Key benefits include:
-
Airflow regulation: Allows you to adjust breathing-air volume to match your needs and working environment.
-
NIOSH-compatible performance: Works with high-pressure supplied air systems while helping maintain compliance with safety airflow requirements.
-
Easy operation: Large grip handle makes adjustment simple even with heavy gloves on.
-
Helmet compatibility: Designed specifically for Allegro Nova 3 and Nova 2000 helmets and related supplied-air components.
This valve is ideal for restoring proper airflow control in existing Nova helmet systems or upgrading from a constant-flow setup when variable control is desired.
