3/8" BSP No-Return (Check) Valve
An in-line check valve, 3/8" male BSP on both ends, installed on the outward flow side of a rotary vane pump to stop water from draining back through the pump when the machine is off. This is a required part on some installations, including La Marzocco (Marzocco part #L032/P.01).
SPECIFICATIONS
- 3/8" male BSP x 3/8" male BSP
- One-way check valve, in-line installation
COMPATIBILITY
- Fits: La Marzocco installations requiring an in-line check valve
- Replaces: La Marzocco part #L032/P.01
- Works with: for CMA-built hydraulics (Astoria, Bravo, Formula, Rio, Wega), use W_225 or AS_232 instead
INSTALLATION
A straightforward DIY job — install it in-line on the pump's outward flow fitting, noting the flow-direction arrow on the valve body.
PRO TIPS
- Install it with the flow arrow pointing away from the pump, in the direction of water travel — installed backwards, it will block flow entirely and the pump will fight a dead-headed line.
- If your machine is a CMA build (Astoria, Bravo, Formula, Rio, Wega) rather than La Marzocco, grab W_225 or AS_232 instead — this exact valve isn't the correct cross-reference for that hydraulic layout.
