Type: Ball valve (quarter-turn shut-off valve)
Load: Handles internal fluid pressure; not designed for mechanical load-bearing
Cage: Not applicable (solid ball with seats instead of cage structure)
Performance: Fast operation, low pressure drop, reliable sealing, long cycle life
Construction: Valve body + perforated ball + seats (PTFE or similar) + stem + handle/actuator
Use cases: Fluid shut-off in pipelines, hydraulic and pneumatic systems, water and oil control, industrial processing
Note: Best for on or off control; not ideal for precise flow regulation as partial opening can cause seat wear

Type: Rotodynamic pump (centrifugal type)
Load: Primarily hydraulic load from fluid movement; radial and axial forces on impeller
Cage: Not applicable (no rolling element cage; uses impeller and shaft system)
Performance: Steady flow, moderate to high efficiency, best for low-viscosity fluids
Construction: Casing, impeller, shaft, seals, bearings, and drive motor
Use cases: Water transfer, irrigation, HVAC systems, industrial fluid movement, cooling circuits
Note: Requires proper priming before operation; avoid dry running and ensure correct sizing for best efficiency

Type: Check valve (non-return valve)
Load: Handles fluid pressure loads in one direction; blocks reverse pressure
Cage: Internal guide or spring mechanism (varies by design such as spring-loaded or swing type)
Performance: Quick response, low backflow leakage, stable operation under varying pressures
Construction: Valve body, seat, disc/ball or poppet, optional spring mechanism, threaded or flanged ends
Use cases: Pumps, compressors, pipelines, hydraulic and pneumatic systems, water and fluid control setups
Note: Install in correct flow direction (marked on body); ensure compatibility with pressure, fluid type, and operating conditions

Type: Elbow fitting (45° / 90°)
Load: Handles internal fluid pressure; minimal mechanical load-bearing role
Cage: Not applicable (no rolling elements)
Performance: Reliable flow direction change with minimal leakage when properly installed
Construction: Solid angled body with threaded, compression, or push-fit ends; made from metal or polymer
Use cases: Pipe routing, tight corner connections, hydraulic/pneumatic systems, plumbing networks
Note: Ensure proper sealing, correct torque during installation, and compatibility with pressure and fluid type to avoid leaks or failures

Type: Pipe connection component (weld neck, slip-on, blind, threaded, lap joint)
Load: Handles internal pressure, bolt clamping force, and external piping loads
Cage: Not applicable (non-bearing component)
Performance: Reliable sealing, high strength, stable under pressure and temperature variations
Construction: Typically forged or cast metal with machined sealing faces and bolt holes
Use cases: Pipe system connections, equipment mounting, flow control assemblies
Note: Ensure correct standard, gasket, and torqueing method to avoid leakage or failure

Type: Gate valve (rising stem or non-rising stem)
Load: Handles fluid pressure loads; not designed for mechanical side loads
Cage: Not applicable (no cage, uses gate/disc mechanism)
Performance: Low pressure drop when fully open; reliable sealing when closed; slower operation compared to other valves
Construction: Valve body + gate (disc) + stem + सीट (seat) + bonnet; typically cast or forged metal construction
Use cases: Pipeline isolation, water systems, oil and gas flow control, industrial shut-off applications
Note: Avoid using for throttling as partial opening can cause wear and vibration; operate in fully open or closed position for best performance

Type: Tee fitting (equal or reducing type)
Load: Handles internal fluid pressure; no mechanical load-bearing function
Cage: Not applicable (no rolling elements or retainers)
Performance: Reliable flow distribution with minimal pressure drop when properly sized
Construction: Solid T-shaped body with three ports; available in metal or high-strength polymer
Use cases: Flow splitting, merging lines, pressure distribution in hydraulic/pneumatic systems
Note: Ensure correct sizing and sealing method; mismatched threads or poor installation can lead to leakage or system inefficiency

Type: Threaded pipe fitting (nipple)
Load: Handles internal fluid pressure; no mechanical load-bearing role
Cage: Not applicable (solid fitting, no moving parts)
Performance: Reliable sealing and connection when properly installed
Construction: Solid cylindrical piece with external threads on both ends (full or partial threading)
Use cases: Pipe extension, joining fittings, adapting system layouts, repairs
Note: Always match thread standards and use proper sealing methods to prevent leaks
