Equipment must be protected against being subjected to an internal vacuum (i.e., low pressure) that is lower than the equipment can withstand. In such cases, vacuum relief valves are used to open at a predetermined low pressure limit and to admit air or an inert gas into the equipment to control the amount of vacuum. Our knowledgeable customer service team will assist you in selecting the proper product specific to your needs and expectations. All vacuum relief valves are verified /tested in our laboratories before being shipment.
