Rugged, Balanced Air-Operated Shutoff Valve Line Expands to 1″, 1 1/2″ and 2″ Sizes
Series BSR/BSRM Balanced Automatic Shutoff Valves provide positive, bubble tight, fail-safe shutoff featuring normally-closed operation. The globe style valve is constructed with no wetted metals; the heavy-duty fail safe spring is isolated by double u-cups on the shaft. Balanced design allows both inlet and outlet pressures up to 150 PSI. The valve shaft is ultra-smooth, and together with the u-cups provides superior non-stick actuation and closure. Series BSR/BSRM is available in Grade 1, Type 1 Geon PVC, as well as non-pigmented natural polypropylene with a choice of FKM (Viton) or EPDM seats. Series BSR/BSRM offers exceptionally long life — tested to 1,000,000 cycles under laboratory conditions. For complete details please click here.
