Common Types of Valves
| Valve Type | Description |
|---|---|
| Ball Valve | Equipped with quick-acting 90-degree turn handles, these valves use a ball to control flow, providing easy on-off control. Faster and easier to operate than gate valves. |
| Butterfly Valve | Compact rotary motion valve with a wafer-type design ideal for tight spaces. Butterfly valve bodies are offered in various configurations. |
| Check Valve | Prevents backflow; self-activated to automatically open when media flows in the intended direction and close when flow reverses. |
| Gate Valve | Common valve type using linear motion to start and stop flow. Typically used in fully open or closed positions, not for flow regulation. |
| Knife Gate Valve | Controls flow of media with solids using a thin gate and linear action. Ideal for grease, oils, paper pulp, slurry, and wastewater but not suited for high-pressure use. |
| Globe Valve | Applied in modulating control operations. Available in three body types: T-body, Y-pattern, and Angle body. |
| Needle Valve | Used in small diameter piping systems for fine, accurate flow control. Named after the conical disc point used within. |
| Pinch Valve | Handles solid materials, slurries, and liquids with suspended solids. Uses linear motion with an internal sleeve to isolate media. |
| Plug Valve | Quick-acting quarter-turn valve handle with tapered or cylindrical plugs. Offers tight shutoff and reliability in high-pressure or high-temperature environments. |
| Pressure Relief Valve | Spring-automated to return a system to desired pressure during over-pressure events, improving safety. |
| Valve Type | Opening Method | Applications | Pros | Cons |
|---|---|---|---|---|
| Ball Valve | Rotary | General on/off control, versatility | Fast operation, tight shutoff | Some pressure loss |
| Butterfly Valve | Rotary | Large pipes, water systems, HVAC | Lightweight, good flow regulation | Limited throttling precision |
| Globe Valve | Linear | Precise flow control, leak prevention | Excellent throttling, tight seal | Higher pressure loss |
| Gate Valve | Linear | Infrequent on/off control | Minimal pressure loss, bidirectional | Not ideal for throttling |
| Check Valve | Automatic | Backflow prevention | Self-operating, protective | Flow in one direction only |
| Pressure Reducing Valve | Automatic | Downstream pressure regulation | Protects equipment, consistent output | Some pressure loss |
| Pressure Relief Valve | Automatic | Overpressure protection | Safety-critical, protects the system | Releases fluid when activated |
| Plug Valve | Rotary | On/off control, slurries | Quick operation, good shutoff | Potential for clogging |
| Needle Valve | Linear | Fine flow control, low flow rates | Precise adjustment | Slow operation |
| Pinch Valve | Linear | Slurries, abrasive media | Self-cleaning, isolates fluid | Limited pressure resistance |
| Diaphragm Valve | Linear | Corrosive fluids, slurries, sterile | Isolates mechanism, leakproof | Can be sensitive to pressure |
| Solenoid Valve | Actuated | Automated control, remote operation | Fast, precise, versatile | Requires electrical power |
| Coaxial Valve | Rotary | Space-constrained applications | Compact, efficient flow | Design can be more complex |
| Angle Seat Valve | Linear | High pressure, flow throttling | Reduced pressure loss, good control | Can be more prone to wear |
