Rotolok has recently manufactured a bespoke Double Roundhead valve to handle free flowing powders for a client in Spain. The Roundheads themselves have Stainless Steel bodies and domes and are designed to operate at a maximum pressure of 8 Barg. They are also certified to ATEX category 2 for use in Zones 1 and 21.
Between the two valves sits an accumulator chamber. The chamber is like the valves made of Stainless Steel and was bespoke for the client. The chamber has a total volume of 0.031 m3 and also has an air purge port.
Hygiene is key
Made for the pharmaceutical industry, the valves adhere to strict regulations regarding the hygiene and design of the valve. The valves and chamber went through numerous designs to maximise hygiene and reduce lodgement points inside. The result was a hygienic valve and chamber, large enough to match the clients needs without taking up too much space.
