Valves are critical components in the chemical industry as they perform several functions. Not only do they deliver precise control and dosing, they also monitor pressure, protect other equipment, and must be compatible with the flow media.

Emergency Shutdown Valve An emergency shutdown valve, frequently referred to as a safety shutdown valve, quickly halts fluid flow in an emergency or potentially hazardous

Direct Acting vs Reverse Acting Actuator Actuators perform important functions in valves, especially control valves. Common operations performed include fully opening, fully closing, and providing

Globe valves are the one most common in the industry. Learn their characteristics, and what dictates globe valve flow direction.

Automated valves do not require manual efforts for their operation. Rather, they possess an actuator and control system that automatically performs the opening, closing, and regulation of the valve. Benefits of this system include increase in efficiency and operator safety. In this article, we review how automated valves work, as well as the functioning of automated gate, globe, and butterfly valves.

Stainless steel valves are one of the most common types because they offer great durability at a relatively low cost. Learn more about stainless steel valves and compare them vs other valve materials.

A check valve is common in control applications to ensure that the flow of liquid or gas is in only one direction. Learn the functions of a check valve in industry, its application in various types of systems, and functionality vs a non-return valve.
