What Is a Valve
A valve is a mechanical device used to start, stop, or regulate the flow of a fluid (liquid, gas, or slurry) through a pipeline or system. Valves can be operated manually, pneumatically, hydraulically, or electrically, depending on the system design and requirements.
10 Types of Valves & Their Functions
1. Gate Valve
Gate valves are designed for full on/off control. They are not suitable for throttling. Commonly used in water and oil pipelines, they offer minimal pressure loss when fully open and tight sealing when closed.
Best for: Isolation in clean service applications like water supply systems and oil & gas pipelines.
2. Globe Valve
Globe valves are ideal for throttling purposes. They offer excellent sealing and precise flow control due to their linear motion design.
Best for: Applications where flow needs to be adjusted frequently, such as cooling systems and fuel oil systems.
3. Ball Valve
Ball valves use a rotary ball with a bore to control flow. With a simple quarter-turn operation, they allow rapid shutoff and are durable under high-pressure conditions.
Best for: Shut-off and control in industrial, chemical, and petrochemical applications.
4. Butterfly Valve
Butterfly valves are compact and cost-effective. They consist of a rotating disc and are well-suited for large-diameter pipes and systems requiring low-pressure drops.
Best for: HVAC, water treatment, and fire protection systems.
5. Check Valve
Check valves are non-return valves that allow fluid to flow in only one direction, preventing backflow that could damage pumps or systems.
Best for: Pump discharge lines, wastewater systems, and process pipelines.
6. Pressure Relief Valve
These valves automatically release pressure when a system exceeds a predefined limit, protecting equipment and personnel from potential damage or danger.
Best for: Safety applications in boilers, pressure vessels, and gas systems.
7. Needle Valve
Needle valves enable fine control of flow rate with a slender, tapered point. Their precision makes them ideal for calibration.
Best for: Instrumentation, metering systems, and flow regulation in low-flow applications.
8. Diaphragm Valve
These valves use a flexible diaphragm to control flow. They are clean and corrosion-resistant, ideal for hygiene-critical systems.
Best for: Pharmaceutical, food processing, and corrosive fluid systems.
9. Plug Valve
Plug valves use a rotating plug with a hole to control flow. Known for their simplicity, they provide reliable shutoff in tough applications.
Best for: Slurry, wastewater, and high-viscosity fluid systems.
10. Pinch Valve
Pinch valves use a pinching mechanism to close off the flow in flexible tubing. They provide full bore flow and are highly resistant to wear.
Best for: Abrasive slurry, powder handling, and mining applications.
