Daniel SERIES 700 EXTERNAL PILOT OPERATED LIQUID CONTROL VALVES PRODUCTS
Product Code: 700 SERIES
Manufacturer: Daniel
Daniel Series 700 External Pilot Operated Liquid Control Valves deliver precision flow and pressure regulation for challenging liquid petroleum and process fluid applications in the oil & gas, custody transfer, terminal and industrial markets.
Engineered with a balanced piston, 45° high-capacity valve body and positive pressure-type O-ring seal, these pilot-operated hydraulic control valves provide smooth linear action, uniform response speed and positive shut-off (ANSI Class VI) across a wide range of operating conditions.
A versatile, cost-effective design allows a single valve body to be fitted with a variety of external pilots for multiple control functions — including back-pressure control, pressure relief, flow limiting and surge control — making them ideal for pipeline flow control, pump modulation, batching and terminal operations. Maintenance is simplified with unit-built construction that lets all internal parts be serviced without removing the valve body or interrupting connections, maximising uptime for refined product handling, storage facilities and industrial fluid management systems.
