The Oyster Compact System consists of a range of high quality general purpose sanitary valves for the Pharma, Food and Chemical industries. The range is a modular range and so the same basic valve can be adapted for tablets, as a rotary dosing valve or as a tablet dosing valve. The range is characterised by exceptional attention to detail in the design to ensure that cleaning and maintenance operations under production conditions are as easy and safe as possible, and certainly much more so than on competitor products. The distinctive famous Clamshell clamp design is the most obvious improvement but there are others. The Compact Mounting collar greatly simplifies fitting the valve into place under IBCs. The Tri-clover as standard connection optimises compatibility with other pharmaceutical machinery. The valve can be offered in a super light weight configuration for applications where weight is an issue, or with a modified design enabling it to be a fully vacuum resistant valve - still with tool free strip down and fully cGMP design features.
