VN-500 Nitrogen Purge Control Valve Regulator And Flow Meter Hybrid Design Nitrogen Purging Regulator w/500psi for leak testing

This valve has well-designed details, is simple to install, and easy to operate. Whether it is fine adjustment or large-scale adjustment, it can respond quickly and maintain stable output, making it very easy to use.

The material is strong and can maintain stable operation even under high pressure. I'm very satisfied with this product!

Bought this one, and it works likea charm, specially while brazing

Very good quality product, z as nd reasonably priced!👍🏼

Great product, works good.

Do not buy this unless you don't mind 400 PSI test pressures. It does not appear to be a true Nitrogen Regulator as its pressure settings are to high and will damage equipment from my experience! The more expensive option that looks the same has a much lower pressure rating for test at around 300 psi while this has a test pressure around 400 PSI which can be to high for some HVAC equipment.

The VN-500 Nitrogen Purge Control Valve is a game-changer for my refrigeration work. Its hybrid design combines a regulator and flow meter, making it easy to control both flow and pressure with precision. The brass body feels incredibly durable, and it’s clearly built to handle high-pressure applications without fail. I also noticed how effective it is at preventing contamination during the purging process, which has been a big help in keeping systems clean and efficient. If you’re looking for a reliable tool to streamline your nitrogen purging, this is it. Highly recommended!

The VN-500 Nitrogen Purge Control Valve Regulator and Flow Meter is a hybrid tool that combines both a regulator and flow meter, designed specifically for nitrogen purging in HVAC systems. Here's a detailed overview based on the product's features and user feedback:Key Features:Hybrid Design: The VN-500 integrates both a regulator and flow meter, allowing precise control over both the pressure and flow of nitrogen during purging.
