Precision High Flow Vacuum Valves
Equilibar’s precision high flow vacuum regulating valves (EVRs) offer unique performance advantages for pipe sizes up to 4″ in size. EVRs are made in two form factors in this size range – The EVR-IC Industrial Collection and the EVR-BD Series – each with their own benefits. The best choice will depend on the application requirements, which you can discuss with our application engineers.
Contact an EngineerEVRs are designed with Equilibar dome-loaded multiple orifice technology, resulting in precision control across a wide range of flow rates. Equilibar precision EVRs have a flexible diaphragm as a control mechanism that is 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 extremely 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. Electronic pilot regulators can be purchased if automating the EVR is your preference.

EVR-IC: Industrial Collection Vacuum Valves
We’re excited to announce the launch of the Equilibar EVR-IC series, our latest innovation in regulating valves. These industrial valves provide best-in-class performance in a compact size and are easily customized for a variety of applications.
Key Advantages of the NEW IC Series:
- Short lead times – Standard lead times of 2-3 weeks for in-stock valves
- Premium materials – Standard offering of dual-certified CF3M/1.4409 stainless steel body material with Hastelloy and most nickel-based alloy options available upon request.
- Flexible process connection options – NPT, ANSI RF Flange, and tri-clamps stocked standard. DIN flanges, BSPP threaded ports, and other connections available upon request.
Currently available in 1.5″, 2″ and 3″ ports in CF3M/1.4409 stainless steel
