The Spirax Sarco BSAT series is a range of in-line bellows sealed stop valves built with twin-ply bellows as standard across the entire lineup. Designed specifically for reliable isolation on steam, gas, liquid, condensate, and water systems, the BSAT variant stands out with its integrated throttling plug and locking device, allowing precise manual flow and pressure adjustment.
Body/Connection Types: Available in screwed, flanged (e.g., PN16, PN25, ANSI 150/300), various sizes from DN15 to larger (specific models like BSA1T, BSA2T, BSA3T). Bellows: Twin-ply construction throughout the range. Plug Type: Throttling plug standard on BSAT series. Locking Device: Included with throttling plug version. Media Compatibility: Steam, gas, liquid, condensate, water. Design Standard: Bellows compliant with MSS SP-117. Compliance: Meets EU Pressure Equipment Directive and UK Pressure Equipment Regulations. Flow Data: Specific Kv values and flow characteristics available for BSA1T, BSA2T, BSA3T models (refer to Spirax Sarco BSAT flow data section in technical info).
Ideal for steam, condensate, and water systems in industrial plants where zero stem leakage is critical for safety and energy savings. Commonly used for isolation duties, manual flow regulation, pressure adjustment, or as a substitute for bypass lines in process, heating, and distribution setups.
Q: What's the main difference between BSAT and standard BSA? A: BSAT includes a throttling plug and locking device for flow/pressure control, while standard BSA uses a flat disc.
Q: Does it really eliminate stem leaks? A: Yes, the twin-ply bellows design guarantees zero emissions from the stem seal.
Q: Can I lock it in a partial open position? A: Absolutely—the standard locking screw lets you secure the throttling position.
Q: Is it suitable for steam systems? A: Yes, specifically designed for steam, gas, liquids, condensate, and water.
Q: How do I know if it's fully open or closed? A: The stem position indicator aligns with + (open) or - (closed) marks on the bonnet pillars.
