Interlocking small diaphragm valves
09 March 2015
Addressing issues in the food, beverage, pharmaceutical and personal care industries, where locking off diaphragm sampling valves can be problematic, Smith Flow Control, has developed a new interlock for use with diaphragm valves in these and other hygiene-critical applications.
The new interlock uses a simple, rotational Ellis lock mechanism that is ideal for this application due to its compact design. It has an Acetal plastic body, which is lightweight and well suited for use with small diaphragm valves.
It is also highly resistant to moisture, solvents and many other neutral chemicals. Despite this, it is tough, hardwearing and has a high resistance to repeated impacts.
The Ellis key has a spring-loaded rubber seal, preventing water ingress during washdown or sterilisation procedures.
