- Concerning the dimensions at the manifold, the holes for the mounting bolts has been fixed to the measure 12, 5 H13. For M 10 and 7/16- 20 UNF mounting bolts, washers have to be used.
- The O-rings' resistance against aggressive media has to be checked. If use of described sealing rings is not possible, you should mount screw connectors into the flanges of the differential pressure measuring instrument. The accessory kits for the mounting of the manifolds and multi-way cocks to the transmitters are shown in section 8, page 8.00.
- The valves and manifolds are manufactured acc. to the DIN EN 61518 type A. The mounting holes are designed for 7/16-20 UNF mounting bolts only.
