Types of Ball Valves

Types of ball valves :   Different types of bores for ball valves – full port, reduce port and V-port. These three types have different constructions and purposes.   Full Port Ball Valve – A full-port, also known as a full bore, ball valve has a bore internal diameter (ID / inside diameter) approximately equal to the pipeline ID. This allows for reduced friction and pressure loss across the valve. With a full port ball valve there is NO restrictions to the flow of medium,…

Keeping your valves in check

Purchasing valves can be a major headache for some. For starters, one must know what kind of valve they are in need of and whether or not it fits their application. The following questions should be asked in order to find the proper valve; –          What is the media? –          What is the temperature? –          What is the pressure? –          Is it an open or closed position? From there, the manufacturer will have a better idea of what the end user is really looking for.…

Lubricants for Your Valves’ Gearbox

Theory: Cold weather dictates a different type of lubricant to avoid seizure and promote proper function inside the gear housing. Global Valve and Controls states, “in order to have a proper functioning valve it is necessary to use the correct grease inside the gear housing.” In a case study where non-cold rated grease is applied to a valve that is heading to Wyoming, where the weather can be frigid seven months out of the year; the likelihood of the valve seizing becomes increased and the…

What are Actuators?

What are actuators? What are actuators and how do they work? There are four types of actuators that are used today.  The most commonly used in this industry are the Pneumatic and Hydraulic actuator. A hydraulic actuator consist of a cylinder or fluid motor that uses hydraulic power to facilitate mechanical operation. The mechanical motion gives an output in terms of linear, rotary or oscillatory motion. Because liquid cannot be compressed, a hydraulic actuator can exert considerable force, but is limited in acceleration and speed. A pneumatic actuator converts…

Global Valve and Controls has become one of the newest organizational members of ASTM

Created in 1898, ASTM International has become one of the largest voluntary standards developing, not-for-profit organizations in the world. ASTM provides a forum for the development and publication of voluntary consensus standards for materials, products, systems, and services from its members. The members of ASTM represent producers, users, consumers, government, and academia from over 100 countries and are responsible for the development of technical documents that are the basis for manufacturing, management, procurement, codes, and regulations. What is a standard? As used in ASTM, a…
