Nu-Check® Valves

The Nu-Check® Valve, designed specifically for pneumatics, is a patented ALADCO product. It is the only check valve on the market with both pilot and manual release capabilities. The unique bubble-tight seal keeps devices in "checked" position. If pressure loss or fluctuation should occur, the valve prevents drifting. To release the seal, simply operate the pilot or depress the manual override button.

  • Prevents load drift
  • Provides emergency and intermediate stopping of load
  • Designed for non-lubricated systems
  • Operating pressure 15-150 psi and temperature 30 - 150° F
  • Flow capacity 0.2 Cv to 4.0 Cv
  • Made of high strength, lightweight, anodized aluminum alloy
  • Exceeds A.N.S.I. bubble-tight safety standards
  • Superior, self-cleaning ball seal provides long product life, over 100 million cycles in test.
  • All valves are manufactured tamper resistant and require no maintenance
