Four Valve Manifold – Double Isolate/Vent Block – Direct Mounting Type
| Designed for where process Fluid Controls must not be contaminated, using differential pressure instruments.
Dimensions shown above are for the standard 54 mm or 2 1/8 inch instrument connection Centre distance found in majority of instruments. The manifold is also available for instruments with other centre distances for instrument connections (as 55 mm, 56 mm and 57 mm) but dimensions shown will vary. Please consult us for these dimensions. The essential feature of this design is a vent/drain valve which is provided with a tamper-proof handle to be removed after operation. This arrangement is especially suitable for applications with hazardous Fluid Controls. |
