Model: SD341XNominal Diameter: DN502000mmNominal Pressure: PN0.61.6MPaOperating Temperature: Soft Seal: X: -40℃ to 90℃, XF: -20℃ to 200℃ Hard Seal: Carbon Steel: -29℃ to 425℃, Stainless Steel: -40℃ to 650℃Applicable Media: Water, air, natural gas, oil, and mildly corrosive fluidsActuation Methods: Worm gear, electric, pneumatic, hydraulic Technical Standards: Body Material: WCB, QT450-10, Stainless Steel Manufacturing Standards: JB/T8527-97, GOST 122387-89 Flange Standards: GOST 9113-2000, GOST 17241.6-1998 Product Overview: The flanged expansion butterfly valve provides automatic compensation for pipeline thermal expansion and contraction, facilitating installation and disassembly. It is ideal for industrial pipelines in petroleum, chemical, power, paper, water supply, and municipal construction sectors operating at temperatures below 120°C and nominal pressures up to 1.6MPa. It is designed for flow regulation and fluid shut-off. Working Principle: The flanged expansion butterfly valve is available in three types: A. Standard Type – Designed per expansion joint specifications. Optional limit bolts available upon request. B. Fixed-Limit Type – Allows expansion but includes a limit mechanism to prevent excessive movement, making it more versatile. C. Extended Type – Features a longer expansion joint to match user requirements. Ideal for pipeline retrofits where replacing valves without cutting existing pipeline connections is necessary. Optional limit mechanisms available upon request. Key Features: Adjustable & Replaceable Sealing – Ensures reliable performance. Compact & Lightweight Design – Easy operation with quick opening/closing. Thermal Expansion Compensation – Prevents pipeline damage from temperature fluctuations while allowing easier valve maintenance and replacement. Installation Precautions: The valve must be stored flat before installation; avoid impacts. Do not remove the support bracket during operation. The valve is shipped at its minimum length. Extend it to the installation length before fitting. If the pipeline length exceeds the valve installation length, adjust the pipeline spacing instead of forcibly stretching the valve. When used for temperature compensation, install support brackets at both ends to prevent overextension.

Flanged Expansion Butterfly Valve Model: SD341XNominal Diameter: DN50–2000mmNominal Pressure: PN0.6–1.6MPaApplicable Temperature: Soft Seal: X: -40℃ to 90℃; XF: -20℃ to 200℃ Hard Seal: Carbon Steel: -29℃ to 425℃; Stainless Steel: -40℃ to 650℃Applicable Medium: Water, air, natural gas, oil, and mildly corrosive fluids Actuation Methods: Worm gear, electric, pneumatic, hydraulic Valve Body Material: WCB, QT450-10, stainless steel Manufacturing Standards: JB/T8527-97, GOST 122387-89 Flange Standards: GOST 9113-2000, GOST 17241.6-1998 Product Overview The flanged expansion butterfly valve is designed to automatically compensate for thermal expansion and contraction in pipelines, facilitating easy installation and removal. It is ideal for industrial pipelines in petroleum, chemical, power, paper-making, water supply & drainage, and municipal construction industries, where temperatures do not exceed 120℃ and nominal pressure is up to 1.6MPa. The valve effectively regulates flow and isolates fluids. Working Principle The flanged expansion butterfly valve is available in three types: Standard Type: Installed according to the expansion joints design specifications. If limit bolts are required, they must be specified during design. Fixed-Limit Type: Provides both expansion and limiting functions, allowing the expansion section to be fixed when necessary. It offers greater functionality and a wider range of applications. Extended Type: Features an extended expansion section to match the required length without considering the expansion amount. This type is particularly useful for pipeline renovations where existing valves need replacement without cutting and modifying pipe connections. If limit measures are needed, they should be specified during design. Product Features Adjustable and replaceable sealing components ensure reliable sealing performance. Unique structure, flexible design, lightweight, easy to operate, and quick to open/close. Compensates for pipeline expansion and contraction due to temperature changes while facilitating maintenance and replacement. Installation Precautions Before installation, the valve should be laid flat to prevent damage. Do not randomly knock or collide with it, and do not remove the support bracket during operation. The valve is shipped at its minimum structural length. During installation, extend it to the designated installation length. If the pipeline gap exceeds the valve’s expansion range, adjust the pipe spacing instead of forcibly stretching the valve, as this may cause damage. The valve can be installed in any direction. When used for temperature compensation, additional supports must be installed at both ends along the pipeline axis after pipeline installation to prevent the expansion section from being pulled out.
