NACE Compliant High Pressure Lee Chek Product Data Sheet

Product catalog summary

Product Overview: The document details the specifications and features of the NACE Compliant High Pressure Lee Chek® Valves, designed for harsh applications in the oil tool industry. These valves are constructed from corrosion-resistant materials compliant with NACE MR0175/ISO 15156 standards and can withstand pressures up to 15,000 psid.

Specifications: The valves are available in five standard sizes, ranging from 0.125" to 0.500" in diameter, with free flow Lohm rates from 400 to 15 Lohms. They are tested for reliable performance, eliminating the need for additional in-house testing. Cracking pressures are specified at 5 ± 3 and 1 ± 0.5 psid.

Materials: The valve components are made from MP35N and Elgiloy materials, ensuring durability and compliance with industry standards.

Installation Instructions: Pins are prewaxed and should not be degreased or lubricated. Specific dimensions for installation holes are provided for each valve size.

Lohm System: The document introduces the Lohm system, a method for defining fluid resistance in hydraulic components, analogous to the Ohm in electrical systems. The Lohm system simplifies calculations by compensating for discharge coefficients and dimensional tolerances.

Flow Calculations: Formulas are provided for calculating flow resistance using Lohms, with compensation factors for liquid density and viscosity. A free slide rule is available to assist with Lohm calculations.
