| Valve Type | Definition & Features | Typical Applications |
|---|---|---|
| PVC Butterfly Valve | Compact structure, rapid open/close. Disc size can exceed pipe diameter constraints. Optional pneumatic or electric actuators enable remote automation. | Municipal water delivery & drainage, reclaimed water systems, chemical corrosion lines, pool water treatment |
| Diaphragm Valve | Flexible diaphragm creates a complete seal with no dead zones—easy to clean. Ideal for media containing solids or suspended particles. | Wastewater treatment, pharmaceuticals, food & beverage, toxic/liquid transfer |
| Gate Valve | Wedge‑shaped gate provides minimal flow resistance and full‑bore passage, resulting in very low pressure drop. Double‑gate designs resist water hammer. | Large‑diameter water networks, water supply engineering, seawater desalination, mine drainage |
| Globe (Globe/Stop) Valve | Fluid passes through a seat and stem arrangement, offering precise throttling control. Soft‑seated options provide excellent shut‑off. | Precision chemical reactors, pipeline flow control, instrumentation, laboratory equipment |
| Ball Valve | 90° rotation of a spherical ball enables quick, simple shut‑off or opening. Compact and offers excellent sealing; “Antiblock” design resists sticking after long idle periods. | Acid/alkali waste lines, seawater circulation, automated production lines, HVAC systems |
| Check Valve | Harnesses forward flow pressure to open the disc, and automatically closes on reverse flow to prevent backflow. Simple, reliable, and low‑maintenance. | Sewage lift stations, cooling water loops, pump discharge lines, chemical circulation |
