Abstract
The invention is concerned with valves generally and more particularly with valves with the type known as pinch valves being those valves which are closed or opened by the action of pinching or releasing a resiliently deformable sleeve. The invention is characterized principally in having a light weight open-sided box section valve housing combined with a pair of substantially cylindrical sleeve supports which allow the use of a resilient sleeve which incorporates no internal bracing.
