Daniel 700 Series Model 760 Back Pressure/ 761 Pressure Relief Control Valves
Product Code: 760 761
Manufacturer: Daniel
The Daniel 700 Series Model 760 and Daniel 700 Series Model 761 are precision pilot-operated pressure control valves engineered for demanding industrial applications where stable inlet pressure is critical. These high-performance liquid control valves are designed to regulate valve inlet pressure within ±2 psi (±13.8 kPa) regardless of variations in flow rate or downstream conditions, making them ideal for pipeline surge control, metering system back pressure regulation, pump discharge back pressure management and pressure relief duty in UK oil & gas and process plant systems.
The balanced, single-seated pilots with large internal ports provide smooth linear valve action with maximum flow and minimum pressure drop, while the robust high-capacity 45° valve body ensures reliable operation across a wide pressure range from 10 up to 1440 psi (60 – 9928 kPa). Designed for extended uptime in critical service environments, these pressure control valves feature positive ANSI Class VI shut-off, fail-safe closure, precision piston sealing unaffected by fluid viscosity changes and modular cartridge construction that simplifies maintenance without removing the valve from the pipeline.
Whether applied as a back pressure regulator to maintain constant pump head or as a pressure relief control valve to protect against excessive line pressure and surge, the Model 760 and 761 deliver dependable pressure control performance for heavy-duty industrial and hydrocarbon handling systems.
- Achieve precise flow rate and batch control with high-performance balanced piston principle, spring-biased design
- Avoid damage due to shock pressure by adjusting closing speed; main piston ensures uniform opening and closing
- Ensure smooth linear action with maximum flow and minimum pressure drop with high-capacity, 45º valve body
- Control pressure from 10 to 1440 psi (60 to 9928 kPa) within ±2 psi (±13.8 kPa) of setpoint
- Safeguard equipment and personnel with positive shutoff (ANSI Class VI) and fail-safe closure upon power loss
- Improve reliability with positive O-ring seal and valve seats that are unaffected by fluid viscosity or pressure drop
- Maximize uptime with all internal parts housed in a cartridge assembly; no need to remove the valve from the line
- Minimize wear-related maintenance with a simple design featuring no diaphragms or stuffing boxes
