Small Check Valves, Big Performance
Check Valves are used extensively throughout industry, simply to prevent unwanted reverse flow. There are many common applications for very large check valves, which are designed specifically to satisfy those requirements. Our whitepaper focuses on the countless industrial applications where small — and even miniature — check valves play a vital role. Incorporated into a system, these check valves help ensure the success of a process, the protection of the equipment, or even the safety of the operating environment and its workers.
Ultra-Precise Flow Data Raises the Bar for Leak Test Standards
Leak detection is essential in many industrial applications. But how do we test and verify the leak testing devices? Learn how ultra-precise flow data raises the bar in leak test standards, allowing accuracy in the most demanding applications.
Understanding Choked Flow of Gases
Do you have an application that requires a precise, repeatable mass flow rate of gas? Our white paper explains the science behind “Choked Flow” or the condition when the velocity of the gas going through an orifice reaches the speed of sound. Also, we cover factors relating to flow that must be considered when choosing a precision orifice to achieve the desired result.
Understanding Standard Conditions in Flow Measurement
Gas flow measurement is usually expressed in volumetric units such as cubic feet, cubic liters, or cubic centimeters per time. Since gases are compressible fluids, the total mass contained in a given volume varies with both the temperature and the pressure of the gas.
To avoid lengthy descriptions of gas flow, science and industry have adopted “standard conditions” of pressure and temperature. However, these vary based on industry. Understanding how standard conditions are defined is critical in gas flow measurement accuracy.
The Vital Role of Tamperproof Flow Controls in Industrial Automation
Flow Controls play a key role in keeping automated processes moving without worry. Once flow rates are established in an application, a tamperproof Flow Control is crucial for maintaining an accurate and repeatable process.
Our white paper explores the three types of Flow Controls offered by O’Keefe Controls. Construction and functionality are explained, along with commonly used applications.
Gas Flow Technical Data
In many industrial applications utilizing gas flow, a highly precise, accurate, repeatable flow is necessary to achieving the desired results. There are several factors to consider in achieving a precise flow of gas through an orifice, including pressure, temperature and specific gravity of the gas. Our technical brief covers these in detail, with conversion formulas and orifice size charts.
Liquid Flow Technical Data
Achieving accurate, repeatable flow rates of liquids is critical to many industrial applications. Our technical brief covers technical considerations and provides liquid flow converstions, along with orifice size charts, for accurate calculation and specification of orifice sizes.
