Pneumatic Adjustable Non-Return Valves in Nickel-Plated Brass
Brand: Legris - by ParkerThese nickel-plated brass adjustable non-return valves, suitable for harsh environments, allow compressed air to flow in one direction and prevent flow in the other. This product incorporates precise adjustment of opening pressure for greater flexibility.
FeaturesRobust
- Excellent resistance to abrasion and corrosion
- Developed for the food process industry
Optimised Inventory Management
- A single valve for multiple opening pressure settings
- Limits the number of versions
- Flexibility of use
Protection & Safety
- Maintains downstream pressure if upstream pressure drops
- Adjustment and locking of the non-return valve cracking pressure with two different Allen keys prevents the settings from being accidentally changed
- Smooth external profile to facilitate cleaning in situ
- Maximum constant flow guaranteed whatever the setting of the cracking pressure
- Designed with locking nut to protect initial setting in the event of:
- Vibration
- Intensive use
- Accidental handling
