Bellows Sealed Stop Valves
Overview
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.

Typical Installation
A typical in-line desuperheater installation. A typical desuperheater installation will require isolation valves for both the steam and cooling water pipelines. The BSA3HP is the ideal solution for use on ASME Class 600 rated desuperheater packages.
