August 2019 Operation parameters Control valve normal operation The Daniel 707 control valves are pressure balanced, single-seated piston operated with 45° body construction. The valves are spring actuated and use pre-loaded spring force to counter the flowing stream. Unique design features and unit-built construction ensures positive leak-proof performance.
The control valve must be cleaned completely inside the housing components and stored/ shipped as it was received. Refer to Storage Preparations for cleaning instructions. After the meter is shut down, refer to Disassembly for the detailed disassembly procedure. User manual www.Daniel.com...
