The kit features twin-ply bellows manufactured from stainless steel grade 1.4571 (EN 10028-7, X6CrNiMTi 17-12-2) and a stainless-steel stem in AISI 420, designed to minimize external stem leakage while maintaining reliable manual isolation in steam systems. As part of Spirax Sarco’s BSA\/BSAT bellows-sealed valve family, the stem bellows set supports the BSA1T\/BSA1 configuration with dual-bellows sealing and is offered across a size range that includes DN15 through DN200. These valves are intended for use on steam, gas, liquid, condensate and water services and find applications across industries such as oil and petrochemical, food and beverage, pulp and paper, and pharmaceutical where leak-tight stem sealing is critical. This stem-bellows kit concentrates on the stem assembly, enabling straightforward maintenance of seal integrity without replacing the entire valve. \u003c\/p\u003e\u003c\/div\u003e","brand":"Spirax","offers":[{"title":"New","offer_id":46259656556778,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-014.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/spirax-sarco-bsa1t-stem-bellows-set-for-steam-valve","provider":"GTG Hardware","version":"1.0","type":"link"}
