BLAKEBOROUGH®

BV990 & BV992 Cage Trim Valves Class 900lb and above

Suitable to general, medium, and severe service applications for low-medium pressure rating, cage guided, quick change trim, available in all configurations.

The cage guided design can accommodate several trims with increasing performance in controlling noise, erosion, and vibration. Trims are interchangeable within the same pressure boundary design allowing ease of upgrade. No trim components are welded or screwed in the body ensuring simple, low cost, in line maintenance.

Additional features available are: soft seating for class VI shut off, downstream silencer for noise reduction, seat diffuser for body protection, balanced pilot for high tight shut off performance, live loaded packing for prolonged high emission protection, extended bonnet for cryogenic and high temperature applications.
