Rain Bird PVBMST 10-Inch Mini-Standard Valve Box

Rain Bird PVBMST 10-Inch Mini-Standard Valve Box

Brand: Rain Bird | SKU: PVBMST

Compatibility & Installation Notes

Measure the entire valve assembly, fittings and working clearance before choosing the Mini-Standard size. A component fitting through the top opening does not by itself ensure enough room to remove a solenoid or service the connections.

Align the pipe slots without loading the enclosure against the pipe. Support the flange and surrounding grade appropriately, keep the lid accessible and provide the intended drainage. A valve box is not a watertight container.

Match replacement lids by model and seating dimensions. The 10-inch designation describes body depth; this is a rectangular Mini-Standard box, not a 10-inch round box. Do not install it in a roadway.

Frequently Asked Questions

Is PVBMST a round 10-inch box?

No. PVBMST is a rectangular Mini-Standard box with a nominal 10-inch body height. Its listed top opening is 15 by 9-1/2 inches.

Is the green lid included?

Yes. PVBMST includes the black box body and drop-in green lid.

How many valves fit inside?

That depends on the valve bodies, fittings, pipe spacing and service clearance. Lay out the complete assembly against the listed openings rather than relying on a fixed valve count.

Does it have a locking lid?

Rain Bird’s model table identifies the PVBMST drop-in lid as non-locking. Choose an enclosure designed for the required access-control arrangement if a lock is needed.

Why Buy from Big Frog Supply?

The PVBMST is useful when the nominal 15 by 9-1/2-inch top opening and 10-inch depth fit the irrigation assembly without moving up to a Standard box. Its included green drop-in lid and compact rectangular footprint suit routine maintenance access; allow extra working space or choose a larger box when fittings and servicing need it.
