A valve is a device that directs or regulates flow by opening, closing, or partially obstructing a passage.

If you aspire to become a piping expert, you’ll also need to familiarize yourself with industrial valves and fittings. Without valves, it’s impossible to control fluid flow in pipelines. Below, Ronishidun Instruments and Valves joins you in reviewing several valve types and their applications.
Gate valve
Gate valves are a common type of valve in industrial applications; when the gate is raised, fluid begins to flow through the pipeline. Gate valves are designed for fully open or fully closed positions and are typically used as shut-off valves to isolate sections of a piping system.
When a gate valve is fully open, there is no obstruction in the flow path, and friction losses are minimal or nonexistent. Gate valves are suitable when straight-line fluid flow is required and minimal restriction is desired.
Gate valves are typically operated by handwheel, pneumatic diaphragm, electric motor, or piston actuator.
Globe valve
A globe valve is used to control flow in a pipeline. Unlike a gate valve, which operates in an “all‑open” or “all‑closed” mode, a globe valve regulates flow by adjusting the position of a movable disc (or plug) relative to a stationary seat.
The ports of a globe valve can be either straight‑through or at an angle. This type of angled‑port valve is typically used for fluids that are prone to solidification, corrosive, or highly viscous.
Needle valve
A needle valve is essentially a type of shut-off valve used for extremely precise flow control. It features a slender, tapered plug that enables highly accurate flow regulation.
Butterfly valve
Butterfly valves are designed for flow regulation, but their control capabilities are limited. They are relatively simple industrial valves that can be operated by rotating the handle 90 degrees.
Check valve
A check valve, also known as an NRV, permits fluid flow in only one direction and is designed to prevent backflow. Numerous types of “shut-off elements” can inhibit reverse flow within a check valve. Ball‑type and piston‑type check valves operate with minimal pressure; the backflow force is insufficient to push the ball or piston in the opposite direction. In rotary check valves, the flow momentum pivots a hinged disc open in one direction, ensuring that fluid cannot flow backward.
Safety valve
A safety valve, also known as a relief valve, is an industrial valve and accessory designed to limit pressure within a system. This type of angle‑type gas supply valve is specifically used to prevent overpressure that could damage the system.
Ball valve
Ball valves offer excellent shut-off performance. A simple quarter-turn of 90 degrees is all it takes to fully open or close the valve. This feature significantly reduces operating time and minimizes the risk of leakage caused by seal‑seat wear.
