Valve Types

Gate vs Globe Valve: What Are the Key Differences? Gate valves and globe valves differ primarily in flow control function and internal design. A gate valve uses a vertically moving gate for full-flow isolation with minimal pressure drop, while a globe valve uses a disc-and-seat arrangement designed for throttling and regulation. Globe valves provide better […]

Ball vs Gate Valve: What Are the Design Differences? Ball valves and gate valves differ primarily in operating mechanism and internal closure design. A ball valve uses a quarter-turn rotating spherical element for rapid isolation, while a gate valve uses a multi-turn linear-moving gate to block or allow flow. Ball valves provide faster actuation and

What Is a Control Valve? A control valve is a power-actuated valve used to regulate fluid flow, pressure, temperature, or level within a process system. It operates by modulating the position of a closure element in response to a control signal, typically from a controller. Control valves are essential components in automated process control loops

What Is a Needle Valve? A needle valve is a linear-motion valve designed for precise flow regulation using a slender, tapered needle-like plunger that fits into a conical seat. By adjusting the stem position, the valve allows fine control of small flow rates. It is commonly used in instrumentation and low-flow applications across process, laboratory,

What Is a Plug Valve? A plug valve is a quarter-turn rotary valve that controls flow using a cylindrical or tapered plug with a through-passage. Rotating the plug 90 degrees aligns or blocks the flow path. Plug valves are primarily used for on/off isolation and are suitable for applications requiring fast operation and compact design.

What Is a Check Valve? A check valve is a self-actuating valve designed to allow fluid flow in one direction and automatically prevent reverse flow. It operates without external actuation, using flow-induced pressure to open and close an internal disc or sealing element. Check valves are commonly used to protect equipment and maintain system integrity

What Is a Butterfly Valve? A butterfly valve is a quarter-turn rotary valve that controls flow using a circular disc mounted on a rotating shaft within the pipeline. When the disc rotates parallel to the flow, the valve opens; when perpendicular, it restricts or stops flow. It is widely used for isolation and moderate throttling

What Is a Globe Valve? A globe valve is a linear-motion valve designed for flow regulation and shutoff using a movable disc and a stationary ring seat within a typically spherical body. The disc moves perpendicular to the seat, allowing precise throttling control. Globe valves inherently create higher pressure drop compared to straight-through isolation valves.

What Is a Gate Valve? A gate valve is a linear-motion isolation valve that uses a wedge-shaped or parallel sliding gate to start or stop fluid flow. The gate moves perpendicular to the flow path, providing minimal pressure drop when fully open. It is primarily designed for full open or full closed service rather than

What Is a Ball Valve? A ball valve is a quarter-turn rotary valve that uses a bored spherical closure element to control fluid flow. When the ball’s bore aligns with the pipeline, flow passes through; when rotated 90 degrees, the solid portion blocks flow. It is primarily used for isolation and tight shutoff in industrial
