Types and Uses of UPVC Compact Ball Valve
1. By Flow Function (Number of Ports)
- 2-Way Compact Ball Valve – Most common: simple on/off control in a straight pipeline.
- 3-Way Compact Ball Valve – Has three ports (L-port or T-port) for diverting or mixing flow in a piping system.
2. By End Connection
- Threaded Compact Ball Valve – BSP or NPT threaded ends for easy assembly/disassembly.
- Socket (Solvent-weld) Compact Ball Valve – Ends designed to be solvent-glued to UPVC pipe for a permanent, leak-proof joint.
- Union Compact Ball Valve – Includes union nuts so the valve can be removed without disturbing the rest of the piping.
- Flanged Compact Ball Valve – For larger pipelines needing stronger mechanical connections (less common in small UPVC but available).
3. By Construction Style
- Single-Piece (One-Piece) Compact Ball Valve – Simplest and most economical; space-saving design.
- Union/Multi-Piece Compact Ball Valve – Has union fittings or multiple parts for easier maintenance or replacement of components (e.g., seats).
4. By Operation / Handle Type
- Standard Lever Handle – Most common manual operating handle for quick quarter-turn action.
- Long Handle Compact Ball Valve – Provides better grip and easier operation in tight or high-pressure situations.
- Short / Compact Handle – Good where space is restricted.
- Actuated Compact Ball Valve – Equipped with pneumatic or electric actuators for automatic control (used in industrial process systems).
5. By Application / Bore Type
- Full Bore (Full Port) – Bore diameter through the ball is equal to pipe size, allowing maximum flow.
- Reduced Bore – Smaller bore than pipe size, usually lighter and cost-effective
