Valves offer much-needed relief
A novel range of automatic relief valves can prevent vacuum or pressure build-up in sealed containers, leading to possible damage.

Stop harmful moisture condensation contamination
Brownell manufactures a wide range of tank vent dryers and adsorbents which prevent valuable fluids from being contaminated by harmful moisture condensation.
Deterioration of gaskets used for sealing is also increased.
This variation in pressure should not be under estimated, for example a surface area of 0.5m2, with applied pressure of 0.07kg/cm2, will result in a loading of 350kg - the equivalent of seven bags of cement.
The pressure and vacuum build-up is automatically equalised using the Brownell relief valve.
The standard opening pressure and vacuum is 0.07kg/cm2, with s nominal flow rate of 0.5m3/min.
There is a wide range of relief valve ratings from millimetres water gauges to 0.07kg/cm2.
Installation is quick and simple by using a locking ring or pipe mounting interface adapter supplied. Request a free brochure from Brownell ...
