Daniel, Series 700 Control Valve, 4 IN (DN100)
Daniel Series 700 External Pilot Operated Liquid Control Valves
Precisely control the flow of liquid petroleum products with Daniel™ Series 700 External Pilot Operated Control Valves that ensure positive sealing, smooth linear action and uniform speed of response.
This versatile, cost-effective line enables a single valve body to be equipped with a variety of external pilots, allowing one valve to serve multiple functions. Unit-built construction allows all internal parts to be removed without interfering with the valve body or connections, simplifying maintenance and maximizing uptime.

Features

  • 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, 45° 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
