Series 840
4-Way / 2-Position
Solenoid and Air Pilot Poppet Valves

Rexroth_Valve_Pneumatic_840

FEATURES

  • 4-Way / 4-ported directional control valve.
  • Compact and lightweight (only 2.6 oz. and requires less than 3 cubic inches of space).
  • Designed to operate on non-lubricated air.
  • Integral fitting (for 1/4˝ plastic tubing) for fast, leak free connections.
  • Modular wireway system.
  • NEMA 4 Electrical Protection (valve only).
  • UL Recognized.
  • "Clip type" valve to manifold mounting means valve installation and removal takes only seconds (similar to Type 740™ concept).
  • Polyacetal Engineering Plastic construction provides excellent corrosion resistance.
  • Poppet type valve design provides millions of trouble free cycles.
  • Manual override standard.
  • Twist lock coil design (no tools required) permits convenient interchangeability between AC and DC coils.
  • 3 Snap together modular manifold sections facilitate most manifold requirements (accommodates 3/8˝ O.D. tubing for both supply and exhaust).
  • Cycle life: 20-100 million cycles.
  • Response time:
    • Supply pressure 90 psi
      Energized (0-81 psi): 16ms
      De-energized (90-9 psi): 18ms
      Response time based on 24 VDC Single Solenoid
