10-551 1/2" NPT modular shut-off valve
Valve can be installed immediately upstream of a single unit or combination of units. The valve is secured to the unit with a modular sleeve or modular sleeve wall mounting bracket. Ball-type valve operates with a 1/4 turn from open to shut position. Particularly useful for isolating and depressurizing a downstream unit requiring maintenance or replacement. Valve can be locked in the open position.
