New BCAS Guidelines published

BCAS launches food and beverage grade compressed air best practice guidelines

New best practice guidance for food and beverage processors on the safe and efficient use of compressed air has been unveiled by the British Compressed Air Society (BCAS).

Prepared in conjunction with BRC Global Standards, the guide is designed to help processors make informed decisions relating to compressor systems operating at a pressure greater than 0.5 bar. It includes information on what type of compressed air equipment could be used, how it should be installed, maintained and audited and, perhaps most importantly, the levels of air purity required to reduce the risk of contamination.

Relief Valves (Josh Cosford)

The most common pressure valve used in hydraulic systems is the relieve valve. Nearly every hydraulic system has one, and they can also be one of the simplest valves in construction. Some relief valves are merely a ball and spring, while most are with a spring with adjustable preload pushing down upon either a poppet or spool. Most other pressure valves, such as counterbalance valves and sequence valves, are a modification of the relief valve.
