Perfect for handling corrosive media or slurry, these valves rely on a flexible diaphragm to manage flow. Their design ensures no contact between the fluid and metal parts.
7. Pressure Relief Valve
A safety device that releases excess pressure automatically, protecting equipment from damage. It’s indispensable for high-pressure systems.
8. Needle Valve
Needle valves provide fine control over flow rates, thanks to their slender, tapered point. Ideal for precise adjustments in laboratory setups or instrumentation systems.
9. Plug Valve
The plug valve features a cylindrical or tapered plug for flow control. Its simple design allows for quick operation in systems with frequent on-off cycles.
10. Pinch Valve
This valve pinches a flexible tube to control flow. Its design ensures no contact between the fluid and valve body, perfect for applications with abrasive media.
11. Solenoid Valve
Electrically operated, solenoid valves control fluid flow with magnetic actuators. These are excellent for automation and remote control in systems requiring rapid cycling.
12. Control Valve
A workhorse for process industries, control valves automatically adjust flow to maintain desired pressure, temperature, or fluid levels.
13. Ball Check Valve
Similar to standard check valves but uses a ball for sealing. It’s simple and reliable for low-flow applications.
14. Angle Valve
By allowing fluid to change direction, angle valves reduce system turbulence. Ideal for corners or compact spaces.
15. Float Valve
Often found in water tanks, float valves use buoyant mechanisms to regulate water levels automatically.
16. Hydraulic Valve
These valves manage flow within hydraulic systems, offering precise control for machinery or industrial equipment.
17. Vacuum Relief Valve
This type prevents vacuum formation in tanks or pipelines, protecting structural integrity by allowing air to enter when needed.
18. Throttle Valve
Throttle valves fine-tune fluid flow by partially obstructing it, used extensively in engine systems or pipelines.
19. Knife Gate Valve
Designed for handling thick media like slurry or pulp, knife gate valves feature a sharp-edged gate to cut through material.
20. Wafer Check Valve
Compact and lightweight, these check valves are sandwiched between flanges, making installation easy in tight spaces.
21. Double Block and Bleed Valve
These valves isolate sections of piping for maintenance or testing, offering dual seals for enhanced safety.
22. Pressure Regulating Valve
By reducing high inlet pressure to a stable output, these valves ensure equipment safety and steady flow.
23. Spring-Loaded Valve
Equipped with springs for actuation, these valves provide automatic shutoff or pressure adjustment capabilities.
24. Three-Way Valve
Ideal for diverting or mixing fluids, these valves have three ports for flexible control options.
25. Four-Way Valve
Primarily used in pneumatic and hydraulic circuits, four-way valves allow fluid redirection between different channels.
26. Magnetic Valve
Similar to solenoids, magnetic valves utilize electromagnetic forces for fluid control in advanced automation systems.
27. Safety Valve
Critical for avoiding overpressure scenarios, safety valves automatically open to vent excess fluid or gas.
28. Y-Strainer Valve
Though technically a filter, this valve-like device traps debris while maintaining flow. It’s essential for protecting sensitive equipment.
29. Toggle Valve
A quick, manually operated valve for simple on-off flow control.
30. Breather Valve
Specially designed for venting systems, breather valves prevent overpressure or vacuum buildup in sealed containers.
31. Piston Valve
A piston valve regulates flow by moving a cylindrical piston, known for excellent sealing in steam systems.
32. Automatic Control Valve
Fully automated, these valves maintain system parameters like pressure or temperature without manual intervention.
33. Cryogenic Valve
Engineered for extremely low temperatures, cryogenic valves handle liquefied gases like nitrogen or oxygen safely.
34. Rotary Valve
Common in bulk material handling, rotary valves regulate solid or powder flow with rotating blades.
35. Zone Valve
Used in HVAC systems, zone valves control heating or cooling in designated areas.
36. Reservoir Valve
A valve ensuring steady liquid levels in reservoir-based systems.
37. Metering Valve
Designed for delivering precise fluid amounts, metering valves are critical in chemical dosing systems.
38. Excess Flow Valve
A safety device that automatically closes when flow exceeds a predefined limit, protecting against leaks or bursts.
39. Double Flanged Valve
With flanges on both ends, these valves offer easy installation and removal in fixed piping systems.
40. Inlet Valve
Regulates fluid entering a system, commonly found in industrial or water systems.
41. Outlet Valve
Controls fluid exiting pipelines, critical for discharge or drainage tasks.
42. Inline Valve
Installed directly within pipelines, inline valves maintain streamlined flow control.
43. Quick Exhaust Valve
This valve rapidly vents air, enhancing pneumatic system efficiency.
44. V-Port Ball Valve
Featuring a V-shaped notch, this valve allows superior flow control and throttling capabilities.
45. High-Pressure Valve
