  • Air to open/close valves and direction of control action

    The type of valve used obviously impacts on what a controller has to do - changing the type of valve would mean that the controller would need to move the manipulation in the opposite direction. To simplify things in this course we shall assume that we are always using air to open valves - an increase in control action will cause the valve to

  • Pneumatic Valves

    Pneumatic valves are used to control compressed air flow to end-use devices and are fundamental building blocks for pneumatic systems.. A previous article provided an overview of typical pneumatic system components.Valves are a fundamental building block for these systems because they translate user or control system commands into compressed air flow to physically actuate field devices.

  • Why Air Valves are Needed in Water Applications

    Air valves are hydromechanical devices designed to automatically release air and wastewater gases or admit air during the filling, draining or operation of liquid piping systems for water and wastewater services. The safe and efficient operation of a liquid piping system is dependent on the continual removal of air and wastewater gases from the liquid piping system.

  • Types of Valves Used in the Oil & Gas Industry

    A flow control valve used in the oil and gas industry can have a globe, butterfly, or ball shape, and is available in multiple material grades and sizes. The most used type of actuator is the air-operated, as it involves less ancillary equipment (as cabling, switchgear) when compared to other types of actuators.

  • Quick and Dirty Guide to Air Release Valves

    Air release valves have small orifices when compared with other types of air valves. Therefore, they're best for applications with smaller volumes of air to exhaust. ADVANTAGES. Air release valves protect the pipeline system and maintain its efficiency. These valves are perfect for quickly venting large volumes of air during filling or startup.

  • Different Types of Valves used in Piping

    A gate valve is the most common type of valve in any process plant. It is a linear motion valve used to start or stop fluid flow. In service, these valves are either in a fully open or fully closed position. Gate valves are used in almost all fluid services such as air, fuel gas, feedwater, steam, lube oil, hydrocarbon, and all most any services.

  • The Hows & Whys of Using Air Admittance Valves

    Operation is simple: when a fixture drains and creates negative air pressure in the correlated drain line, the valve is opened, drawing air back into the pipe. Once the air pressure has been equalized, the valve securely closes (preventing the escape of gas) until the pressure drops again. AAVs can be used to service an individual fixture or
