OSVB25
OSVB25 replaces the cast OSV25 with New part number and billet design.
The Maxton OSVB25 safety shut off valve is designed to provide protection against supply line failure or overspeed in the down direction in residential/LULA elevator overspeed valve applications. Use the Maxton valve calculator for valve sizing to the job specifications. The OSVB25 is used in low flow system applications (24 gpm max,90.8 l/min max) with 3/4" NPT connection. The OSVB25 can be adjusted to stop the elevator in the event of an overspeed condition caused by a broken supply line or an abnormally high rate of flow between the OSVB25 valve and the power unit. The OSVB25 complies with ASME A17.1/CSA B44.
