ALADCO
Pilot Operated Pneumatic Check Valves
Aladco® is a leading manufacturer of pilot operated pneumatic check valves with both manual and pilot release capabilities
Aladco® has a proven commitment of manufacturing pilot operated pneumatic check valves that are built to last. Our valves are specifically designed to maximize reliability and safety. We continuously strive to understand and fulfill our customers’ technical needs. With that in mind, Aladco® incorporates varying design and function in each pneumatic check valve to meet a variety of application needs.
Nu-Check Pneumatic Check Valves
The Aladco® Nu-Check® valve is a normally closed check valve that can be either overridden manually or by air piloting to allow two-way flow.
- Superior, self-cleaning ball seal provides long product life
- Exceeds ANSI Class VI Leak Standard (bubble tight)
- Made of high strength, lightweight, anodized 6061 aluminum alloy
- Variety of porting options
- Designed for use with lubricated or non-lubricated air systems
- Tamper resistant with no required maintenance
- Prevents load drift and provides rapid stopping of load
- Patented and Made in Waukesha, Wisconsin USA
- Standard 3-year warranty
CLEAN-CHECK PNEUMATIC CHECK VALVES
Aladco® Clean-Check® valve is a normally closed check valve that can be overridden by air piloting or manually to allow two-way flow. The tightly sealed Clean-Check® valves are used on pneumatic devices to stop air release when the device is stopped, which prevents drifting of the device and any attached load. Clean-Check® valves are unique in that they can be used in environments that need to stay very clean, but they also can tolerate exposure to external dirt and liquids.
- Superior, self-cleaning ball seal provides long product life
- Exceeds ANSI Class VI Leak Standard (bubble tight)
- Body is made of high strength, lightweight, anodized 6061 aluminum alloy (Stainless Steel 303 is optional in some models)
- Variety of porting options
- Designed for use with lubricated or non-lubricated air systems
- Tamper resistant with no required maintenance
- Prevents load drift and provides rapid stopping of load
- Fully sealed for use in clean/sanitary environments
- Patented and Made in Waukesha, Wisconsin USA
- Standard 3-year warranty
EQUA-CHECK PNEUMATIC CHECK VALVES
The Equa-Check® valve is the only check valve on the market with both manual and pilot release capabilities. Equa-Check® valves are pilot operated check valves where the pilot pressure is balanced by the IN chamber pressure. Load balancing systems are a type of application that can benefit from the functions of an Equa-Check® valve.
- Superior, self-cleaning ball seal provides long product life
- Exceeds ANSI Class VI Leak Standard (bubble tight)
- Body is made of high strength, lightweight, anodized 6061 aluminum alloy (Stainless Steel 303 is optional in some models)
- Variety of porting options
- Designed for use with lubricated or non-lubricated air systems
- Tamper resistant with no required maintenance
- Prevents load drift and provides rapid stopping of load
- Patented and Made in Waukesha, Wisconsin USA
- Standard 3-year warranty
DUAL-CHECK PNEUMATIC CHECK VALVES
Aladco® double check valves use two check valves in the same body. Double check valves trap air in both sides of a cylinder or actuator and the pilot operation automatically pilots the opposite check allowing the cylinder to move. Our patented manual override relieves the air on both sides of the cylinder or actuator. One manual override button creates a better-controlled and safer release of air because it relieves air from both sides of the cylinder simultaneously.
