3/8" BSP Ball Valve (Closing Valve)
A 3/8" male BSP x 3/8" female BSP ball valve — the most common shutoff valve configuration used in espresso machine plumbing, with a quarter-turn lever handle for quick on/off control.
SPECIFICATIONS
- 3/8" male BSP x 3/8" female BSP
- Quarter-turn ball valve with lever handle
COMPATIBILITY
- Fits: general espresso machine plumbing using 3/8" BSP shutoff valves, including La San Marco machines
- Replaces: also see V_531 or SM_527 for the 1/4" configuration
INSTALLATION
A simple DIY swap — hand-thread and snug with a wrench, confirming the handle has full quarter-turn travel once installed.
PRO TIPS
- Double-check this against your parts diagram before ordering — this exact valve is listed incorrectly on some La San Marco exploded diagrams, so match by thread size and gender (3/8" M x 3/8" F) rather than by diagram part callout alone.
