High Flow Vacuum Valves

High Flow Vacuum Valves Manual Operation

Equilibar’s high flow vacuum regulating valves offer unique performance advantages for pipe sizes up to 4″ in size.

Equilibar’s patented technology offers lightning-fast response that is mechanically native, with zero hysteresis or deadband.

PVC is our most popular body material for air applications, with SS316L available for chemical applications. Most vacuum regulators are outfitted with FKM Viton diaphragms, with PTFE also available for highly aggressive chemistries.

Our vacuum regulators work in a very different way from vacuum breakers. Learn more about how they work.

Equilibar Design Provides Unique High Speed Vacuum Control

Equilibar’s EVR vacuum regulators feature an inherently fast-reacting design that automatically compensates for changes in flow rate.  They offer multiple advantages over traditional vacuum control valves that typically rely on an external control loop and I/P actuator. Unlike traditional valves, the Equilibar vacuum regulator uses a pilot operated design with a flexible diaphragm as the […]
