Precision High Flow Vacuum Valves
Equilibar’s precision 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. Equilibar precision vacuum regulators work differently with a flexible diaphragm as the only moving part. This diaphragm directly seals against the internal valve orifices, eliminating the “stiction” commonly found in traditional vacuum control valves with dynamic O-ring or wiper type seals. The Equilibar design is frictionless and can control vacuum with very high resolution. Learn more about how they work.
Our precision high flow vacuum valves are available in sizes ranging from 1 1/2″ to 4″ with material options of stainless steel 316/316L, anodized aluminum or PVC depending on the application requirements for temperature and chemical resistance. Each EVR is delivered with a manual pilot setpoint regulator for convenient knob adjustment.

Videos about Precision Vacuum Regulators
This video shows how the Equilibar vacuum regulator maintains high accuracy and resolution even as the supply vacuum pressure changes and system flow varies from high flow rates to low flow rates.
