ALADCO Pneumatic Check Valves from Flotronics Automation
If you need a dependable way to hold pressure, stop cylinder drift, and keep loads steady during pauses or E-stops, ALADCO pneumatic check valves are a proven solution. As a supplier, Flotronics Automation and The Pneumatics Store make it easy to spec and order ALADCO components for industrial automation. Learn more about the manufacturer at ALADCO.
What Are ALADCO Pilot-Operated Pneumatic Check Valves?
ALADCO specializes in pneumatic check valves designed to hold air pressure in a circuit until a pilot signal (or manual override, depending on configuration) allows flow. In real-world automation, that means better control when machines pause—especially where you want to prevent movement of cylinders, grippers, clamps, or tooling when air supply changes.
- Hold position: Helps reduce cylinder drift and unintended motion during stops.
- Improve safety & quality: Keeps tooling steady for consistent results.
- Protect uptime: Minimizes “mystery movement” that causes rework or troubleshooting.
Where ALADCO Valves Add the Most Value
ALADCO check valves are commonly used anywhere a pneumatic device needs to hold a load or maintain a position. Typical applications include:
- End-of-arm tooling (EOAT): Maintain grip position and reduce drop risk during pauses.
- Clamping & fixturing: Keep clamps engaged to stabilize parts throughout the cycle.
- Vertical cylinders: Reduce drift caused by load changes or supply pressure variations.
- Automated assembly: Maintain consistent force/position for repeatable processes.

Selection Guide: Choosing the Right ALADCO Valve
Use this quick guide to narrow your choice. If you want a fast recommendation (or you’re replacing an existing valve), contact our sales team.
| Selection Factor | What to Consider | Why It Matters |
|---|---|---|
| Port Size / Thread | Match your tubing/fitting standard (ex: 1/4", 3/8", 1/2" NPT) | Ensures correct flow and easy retrofit |
| Hold vs. Release Method | Pilot release, manual override, or both (by model) | Controls how/when the load is allowed to move |
| Pressure & Environment | System pressure range, duty cycle, plant conditions | Protects reliability and long-term performance |
| Mounting / Layout | Inline installation, access for service, orientation constraints | Improves maintainability and reduces downtime |
