Product detail

DIGITAL CONTROL VALVES
DIGITAL CONTROL VALVES

Features : 

  • Effective planning and execution of maintenance and product lifecycle strategies is essential to meeting production and metering targets, and keeping costs low. The right mix of maintenance activities will help you operate safely, consistently and economy
  • Avoid damage due to shock pressure with adjustable control of closing speed
  • Reduce pressure drop and maintenance compared to axial flow valves with high-capacity, 45º piston operation
  • Control pressure from 60 to 9928 kPa (10 to 1440 psi) within ±13.8 kPa (±2 psi) of setpoint
  • Improve reliability with positive O-ring seal and valve seats not affected by fluid viscosity and pressure drop
  • Protect equipment and personnel with positive shutoff (ANSI Class VI) and fail-safe closure upon power loss
  • 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
