OBJECTIVE

The Model 4600 spring-loaded vacuum relief vents are intended for use on low pressure tanks, vapor recovery systems and process systems where higher vacuum relief is required.

TECHNIQUE

The spring-loaded pallet in the vent housing allows the intake of air necessary to maintain the tank pressure within the permissible vacuum limit to avoid damage to the tank. Once the vacuum condition is satisfied and the pressure is within the permissible limits the spring-loaded pallet closes. The Model 4600 virtually eliminates the intake of air except during normal tank in breathing.
