Engineering notes Caution The characteristics of the main valve and the manufacturer's recommendations must be observed. Mounting notes Mounting instructions are enclosed with the valve: ∂ Nr. 35552 (pilot valve) The pilot valve can be mounted in any orientation, but upright mounting is preferable. To protect the valve from dirt, a mesh filter should be fitted on the supply side (mesh gauge 0.1...0.2 mm).
