Vacuum Relief Valves For Negative Pressure Systems
A reliable vacuum relief valve could save you thousands of dollars in costly repairs. Vacuum relief valves are responsible for maintaining the balance of negative pressure within a closed system. Too much vacuum can cause catastrophic failure in your pipes, HVAC system, storage tank or hydraulic system. Our vacuum relief valves are made using a bayloy body with a bronze poppet for the best corrosion resistance and durability.

What Are the Major Types of Pressure Relief Valves?
The two prominent varieties of pressure relief valve both work to keep your systems safe. Pressure relief valves seek to release excessive pressure from systems to maintain operational levels. By contrast, vacuum relief valves allow air to enter into negative pressure (vacuum) systems to prevent an excess buildup of vacuum, which can cause damage to sensitive systems and components.
Who Uses Vacuum Relief Valves?
Several industries use vacuum systems in their day-to-day operations. Used for everything from equipment to pipelines, storage tanks and processing systems, the industries that use vacuum relief valves include:
- Oil and Gas
- Power Generation
- Food and Beverage
- Bulk Storage Tanks
- Pulp and Paper
- Water Treatment
What Is the Difference Between a Vacuum Relief Valve Vs. a Vacuum Breaker?
The primary use of vacuum relief valves is to prevent overpressurization within a closed system. It is a valuable safety device and helps to maintain pressure within operational guidelines. A vacuum breaker is used to prevent contaminated water from backflowing into a potable water supply. The vacuum breaker will automatically break the vacuum that could develop within your plumbing system and maintains normal atmospheric pressure to prevent contamination.
