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.

Additional information

Material	SS – stainless steel

The centric WAFER-type butterfly valve is a reliable solution designed for industrial gas installations in pressure class MOP5, ensuring safe and efficient flow control. It can be operated manually or equipped with a pneumatic actuator, while the ergonomic aluminum lever allows precise positioning in nine stages, including fully open, fully closed, and intermediate settings. Manufactured in compliance with the PED Directive 2014/68/EU and certified by NF ROBGAZ according to EN 13774 and EN 549, the valve guarantees high safety and quality standards. The robust body is made of ductile iron EN-GJS-500-7 with an epoxy coating of 250–300 µm, providing excellent resistance to corrosion and mechanical stress. Depending on the size, the disc is crafted from stainless steel CF8M (up to DN100) or ductile iron EN-GJS-500-7 (from DN125), while the stem is produced from durable stainless steel AISI 420. The sealing system with NBR ensures tightness and reliability in demanding conditions. With flange connections PN10/PN16 for DN32–DN200 and ASA150 for DN40–DN200, the valve offers versatile installation options. Designed to operate in a temperature range from -20°C to +60°C, it delivers consistent performance, making it an ideal choice for modern gas distribution systems where durability, safety, and operational flexibility are essential.
