Spirax Sarco BSAT and BSA Bellows Sealed Stop Valves
Our bellows sealed isolation valves are engineered to maintain plant safety and save energy by totally eliminating stem seal leaks. Zero emissions are guaranteed which ensures our BSA valves meet the most stringent worldwide emissions legislation.
The BSA_T offers a throttling plug as opposed to the standard flat disc. The throttling plug allows manual regulation to adjust line pressure and flow, making this a flexible and user-friendly isolation solution. It can also be used as a basic control valve or a substitute for ‘bypass’ lines. The throttling plug version also benefits from having twin ply bellows which will extend the product's service life.
Those valves fitted with a throttling plug have a locking screw as standard, enabling the user to lock the valve in the throttling position.
