LEGRIS ADJUSTABLE CHECKVALV 7931 10 10

These 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.

Features/Benefits:

- Robust
• 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
• Designed with locking nut to protect initial setting in the event of:
Vibration
Intensive use
Accidental handling
• 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
