Caleffi North America introduces new vacuum relief valve

CALEFFI NORTH AMERICA

VACUUM RELIEF VALVE

Introducing Caleffi's New Vacu-Stop™ Vacuum Relief Valve (VRV). Available in ½” and ¾” MNPT, the Vacu-Stop is suitable for use in water and low-pressure steam services. It is ideal for use in water heaters, supply tanks and low-pressure steam systems. The valve automatically allows air into the piping system to prevent a vacuum which could siphon water from the system and damage water heater/tank equipment.

The Vacu-Stop meets ANSI Z22.21 Standard and is compliant with International Plumbing Code (IPC) Section 504.2 governing safety devices. It is also NSF 61 and NSF 372 compliant making it usable in potable water environments.
