Caleffi North America introduces new vacuum relief valve
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.
