Pratt AirPro Max Water Air Release Valves Now FM Approved

In addition to meeting the ANSI/AWWA C512 and NSF 61/372 standards, Pratt AirPro Max water air release (WAR) valves have been fully tested by FM Global and are FM approved.

Designed to vent trapped air that collects at high points in a water or wastewater pipeline, AirPro Max WAR valves help to prevent damaging pressure surges. The body and cover are cast from ductile iron (ASTM A536 65-45-12), protected with fusion bonded epoxy coating on interior and exterior surfaces, and the float is manufactured from grade 316 stainless steel resulting in an extremely durable and corrosion resistant engineered product.

With pressure ratings up to 300 psi, UL listed and FM approved Pratt AirPro Max WAR valves are available in a variety of styles and configurations. For more information, contact your local Pratt sales representative or visit to download the handy sizing calculator.
