Is the Manual Gas Butterfly Valve Type 1141H compatible with both PN10/PN16 and ASA150 flange connections for DN40–DN200?

Yes. Manual Gas Butterfly Valve Type 1141H is compatible with both PN10/PN16 and ASA150 flange connections for the DN40–DN200 range. The product offers PN10/PN16 flanges for DN32–DN200 and ASA150 flanges for DN40–DN200, so DN40–DN200 sizes support either flange standard.

Can the Manual Gas Butterfly Valve Type 1141H maintain reliable sealing and performance across its full operating temperature range of -20°C to +60°C?

Yes. The Manual Gas Butterfly Valve Type 1141H is designed and certified to operate reliably across the full stated temperature range of -20°C to +60°C. Key factors supporting this include: - NBR sealing system specified for gas duty, providing reliable tightness within the stated temperature window. - Robust materials: ductile iron body (EN‑GJS‑500‑7) with thick epoxy coating (250–300 µm) for corrosion and mechanical resistance; stainless steel disc (CF8M up to DN100) or ductile iron disc (from DN125); and AISI 420 stainless steel stem for durability and dimensional stability. - Compliance and certifications (PED 2014/68/EU, NF ROBGAZ to EN 13774 and EN 549) demonstrate design and testing appropriate for safe gas service in that temperature range. - Manual ergonomic lever with nine discrete positions ensures predictable operation and sealing at intermediate and end positions across ambient and operating temperature extremes within the specified limits. As with any installation, reliable field performance assumes correct selection for the application, proper sizing, installation, and routine maintenance; if lower or higher temperatures, aggressive fluids, or atypical duty cycles are expected, consult the manufacturer for material/seal alternatives or additional verification.
