When fluid drops below a liquid's vapor pressure, a gas is formed. As fluid moves downstream to where the fluid pressure is greater than the vapor pressure, it "collapses" back into a liquid.

The first stage of cavitation is the formation of vapor bubbles within the liquid system because of the fluid's static pressure falling below the fluid vapor pressure

A resource for engineers, plant managers and distributors, this catalog provides customers with product specifications, dimensional information, Cv values, and pressure versus temperature ratings.

The shaft speed of a motor is directly proportional to the frequency and is inversely proportional to the number of poles.

The Endress+Hauser product portfolio of electromagnetic flowmeters is designed for precise measurement of volume flow without restricting production flow rates or causing any pressure drop.

The U.S. industrial valve industry will see growth of 1.45% in valve shipments in 2018, a rate that brings the value of those shipments up to $4.615 billion for the year. That rate of growth is slightly behind 2017 when it was 1.89%, which translated to shipments worth $4.549 billion.

Designed exclusively to meet the needs of LDAR and air compliance professionals, the three-day event, to be held 5-8 March 2018 in Galveston, Texas, features a technical program and lineup of expert speakers as well as ISA-led training, a vendor exhibition and networking activities.

The plant will give the centers of competence for flow measurement engineering, liquid analysis and temperature measurement engineering additional capacity.

By Philip Allen, Grace Engineered Products Without question, the highest risk task for qualified electrical workers is creating an electrically safe work condition. Validated installation procedures for PESDs combined with LOTO procedures significantly reduces the likelihood that workers will be exposed to voltage when creating that electrically safe work condition.

The volts-per-hertz ratio (V/Hz) controls the torque of a motor.

In the gravity filter plant, 18 butterfly valves are situated in an area beneath a walkway which made it difficult to access and operate the old actuators. With the Rotork actuators, the installation of Remote Hand Stations (RHS) has now eliminated this problem.

In connection to Kamstrup’s visit in Iran, the company signed both a partner contract and an agreement of two pilot projects with the local Iranian company Iran Ensheab Co. The projects include intelligent water meters and remote reading system.

In general use the highest valve positioner gain that does not cause oscillation. For pipeline flow and pressure control, oscillations are not filtered.

Research offers fault detection technique for insulated-gate bipolar transistors open-circuit faults in voltage source inverter-fed induction motor drives.

By Jon Moscovic, Lead Reliability Engineer, SABIC SABIC’s situation proved to be harder than most typical applications due to a mix of specific conditions. For many years operators struggled while working with paramagnetic and electrochemical cell sensors.

Through demonstrations, presentations and one-on-one discussion with leak test experts, the Nov. 8 Leak Test Workshop will give practical information and ideas that attendees can take back to their factories and implement for a better, faster and more reliable leak test.

An actuator is a device that applies the force necessary to cause a valve's closure member to move.

The Egyptian Construction Authority for Potable Water and Wastewater (CAPW) recently sourced four custom-made pump drives from special motor manufacturer Menzel Elektromotoren for installation in a water pump station in Cairo.

The aim of the project is to increase the field's oil production capacity to 65,000 barrels per day (BPD) from the existing capacity of 22,000 BPD.

In plant installations, a key requirement is the ability to smoothly integrate actuators used for opening or closing valves with the automation system.
