Fixed Orifice, Pressure Compensated

  • Maximum operating pressure = 5000 psi
  • Customer must specify flow setting
  • Accurate pressure compensated control requires that a 200 psi minimum pressure differential be maintained across the valve.
  • The tuneable control option provides +/- 25% variation from the nominal factory pre-set flow.

Electro-proportional, Normally Closed Throttle

  • Maximum operating pressure = 5000 psi
  • Maximum valve leakage = 6 in³/min. at 3000 psi
  • For optimum performance, an amplifier with current sensing and adjustable dither should be used.
  • Dither should be adjustable between 100 - 250 Hz.

Electro-proportional, Normally Open Throttle

  • Maximum operating pressure = 5000 psi
  • Maximum valve leakage = 6 in³/min. at 3000 psi
  • For optimum performance, an amplifier with current sensing and adjustable dither should be used.
  • Dither should be adjustable between 100 - 250 Hz.
