Pneumatic Adjustable Non-Return Valves in Nickel-Plated Brass

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.

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
