NRV ( Non Return Valve )

About the SPA2Z Sand Blasting Non Return Valve

This non-return valve is manufactured with the specific demands of sand blasting operations in mind. Unlike general-purpose check valves, our NRV is built to handle the abrasive nature of blasting media. The brass body offers a practical balance of corrosion resistance, machinability, and durability for industrial surface preparation equipment.

We understand that space constraints inside a blasting machine or hose assembly can be a challenge. Our NRV features a compact face-to-face dimension, making it easier to integrate into existing setups without major modifications. The valve is available in both spring-loaded and non-spring-loaded configurations, allowing you to choose the right cracking pressure and response for your specific system.

Key Features and Benefits

• Unidirectional Flow Control: Prevents abrasive media and compressed air from reversing direction, which can cause equipment damage, inconsistent blasting, and safety hazards.
• Compact, Lightweight Design: Engineered for applications where weight and space are at a premium, simplifying installation in tight machine layouts.
• Durable Brass Construction: Provides reliable performance and resistance to the wear and tear of abrasive environments, extending service life compared to standard steel valves.
• Configurable Spring Option: Available with or without an internal spring, allowing you to specify the valve's opening pressure based on your system's requirements.
• Standard Connection Sizes: Offered in 20 mm, 25 mm, and 31.5 mm sizes to directly match common sand blasting hose and pipe diameters, reducing the need for additional adapters.

Applications in Surface Preparation

This brass NRV is a direct-fit spare part for various sand blasting and shot blasting equipment. It is typically installed in the media supply line, between the abrasive metering valve and the blast nozzle, or on the air intake of a blast pot. Its primary role is to stop moist, contaminated air or abrasive slurry from being sucked back into the compressor or media storage when the blast trigger is released.

Common equipment types that utilize this component include portable sand blasting pots, cabinet blasters, and automated blasting rooms. If you are unsure about the correct size or configuration for your machine, please contact us with your equipment model or existing valve dimensions for a technical consultation.
