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 strive to provide earth friendly options

Global Valve and Controls strive to provide earth friendly options, especially the containment of fugitive emissions being released in the earth’s atmosphere.  Over 44% of a plant’s expense, is due to leaking valves and the replacement of them because of old technology, such as the Chevron design.  GVC has a new technology to lower this expense by a substanial decreased cost of ownership. GVC has been manufacturing an accessory, the Media Containment Bonnet, since 2004.  The MCB is unique because of the installation, maintenace and application, as…
