Lee Products has introduced a range of high-pressure check valves for harsh-duty applications that are compliant with material standards set by the National Association of Corrosion Engineers (NACE).

The valves are constructed entirely from corrosion-resistant materials that are compliant with NACE MR0175 and ISO 15156 standards, making them suitable for harsh-duty applications, such as chemical injection in oil-tool applications.

The valves are offered in a choice of five standard sizes (as small as .125in diameter) and feature a durable MP35N poppet and seat.

They are designed for checked direction pressures of up to 15,000psid and are available in free-flow forward and free-flow reverse directions, with cracking pressures of 5+/-3 and 1+0.5psid.

Sizes range from .125 up to .500in diameter, providing free-flow Lohm rates from 400 down to 15 Lohms.

According to Lee Products, each valve is tested and inspected to ensure a reliable and consistent performance that eliminates the need for additional in-house testing.

Thanks to their design and materials of construction, Lee’s NACE-compliant check valves will withstand the effects of challenging environments such as those in the oil tool industry.
