Vacuum Safety Valve Kits for Ebara EV-A series pumps.

Ebara’s Vacuum Safety Valve protects a vacuum system upon power failure by isolating the key system and venting the mechanical pump. When power returns, the Vacuum Safety Valve vents the mechanical pump to atmospheric pressure for easy restart. Since the valve operates with atmospheric pressure and triggers upon loss of power, no external pressurized gas source is required. Ebara offers customized Safety Valve Kits in KF25/40/50 flange sizes, and is available for all Ebara EV-A series pump models (EV-A03/06/10) in 120VAC and 240VAC variants.
