Choosing Between Bronze and Brass Valves

While a valve's intended application often determines its composition, as one media or another may be more compatible, it's not always clear as to why this is true. Choices of materials, however, are limited to man's metallurgical prowess. Two of the most common materials used to produce valves are bronze and brass. This preference came [...]

How Do Cryogenic Valves Work?

As its name suggests, cryogenic valves are designed to be used in very cold applications. They are thus most popularly used by companies that work with Liquefied Natural Gas (LNG) or Compressed Natural Gas (CNG). For instance, the oil and gas industry frequently uses cryogenic temperature ranges starting at -238 degrees Fahrenheit (-150 degrees Celcius). [...]

How Do Ball Valves Work?

A  ball valve, as its name neatly suggests, is any valve that utilizes a ball to control the flow of substances from one opening to the next.  The center of the ball includes a port, sometimes called a bore.  The ball valve is in the open position when this central port [...]

The Difference Between #150, #300, and #600 Pound Flanges

What is the Difference Between #150, #300, and #600 Pound Flanges? Pressure class definitions for flanged valves can be a little confusing at first, but they're actually quite simple.  Part of the confusion in this rating system stems from the interchangeability of the pound symbol--#--the abbreviation, lb or lbs, and pound or pounds.  While all of these [...]

Deciphering Backflow Preventers

When a simple check valve is inadequate for the job, you need a backflow preventer. But knowing you need one and understanding how they work are two different things entirely. Unlike an inline check valve, which prevents fluid from traveling backwards through the system, a backflow preventer is far more complicated, [...]

Choosing Between a Double Acting and Spring Return Actuator

Most types of  valves will require one of two types of actuators to use: the spring return (also known as the single acting) actuator and the double acting actuator.  While there are a variety of other types and categories of actuators, these two are the most important and are frequently the go-to choice for use in [...]

Types of Ball Valves

Types of Ball Valves The ball valve revolutionized the valve world. Utilizing an otherwise solid ball with a hole bored through the center, a ball valve is a quarter turn valve that is normally open, or normally closed. The perforation through the ball allows media travel when in line with the inlet and outlet ports, and visa [...]

Why Choose a Namur Solenoid Valve for a Pneumatic Actuator

The word, NAMUR, somewhat a misnomer, is an acronym for the User Association of Automation Technology in Process Industries, and serves as a standard for automated valve technology.  Standard interfaces for  actuator mountings keeps solenoid and installation costs down.  A NAMUR solenoid valve, therefore, is directly mounted to pneumatic actuator inlet/outlet ports. [...]
