The BSA3HP is a high quality, zero emission bellows sealed stop valve in carbon steel for pressure ratings up to PN100 and ASME Class 600. The valve has been engineered to allow fast, easy maintenance to ensure minimal process down-time.
The 'clamp-in-place' design of the internal seat allows the seat to be replaced without special tools and without having to remove the valve from the line.
A carbon steel bodied, high pressure in-line nonthrottling stop valve with multi-ply bellows. Balanced and unbalanced options are available. These valves are rated to EN 1092 PN100 or ASME class 600 for use with both saturated and superheated steam applications and a range of other industrial gases and fluids.
