Product Description
NAI-LOK 1/4 Inch SS316 Check Valve is a high pressure non return valve designed to control fluid flow and prevent reverse flow in industrial fluid and gas systems. With a maximum pressure rating of 6000 PSI, this stainless steel check valve is suitable for demanding high-pressure applications where reliable one-way flow control is required.
The valve body is manufactured from Stainless Steel 316, providing good corrosion resistance and durability for industrial service. Its compact design makes the check valve suitable for installation in instrumentation, process piping and fluid control systems where space and reliable flow direction control are important.
This high pressure check valve allows flow in one direction while automatically preventing backflow when the upstream pressure decreases or the flow direction changes. The non return valve design helps protect downstream equipment and maintain stable system operation.
• Maximum pressure rating up to 6000 PSI
• 1/4 inch connection size
• Automatic one-way flow control
• Prevents reverse flow and backflow
• Compact design for easy system integration
• Suitable for high-pressure gas and liquid service
• Corrosion-resistant stainless steel construction
• Reliable solution for industrial fluid control
