horizontal lift check valve Description
Horizontal lifting check valve is an automatic valve designed for horizontal pipelines. It realizes one-way flow control by vertical lifting of the valve disc, and relies on the medium's own pressure or gravity to open and close to prevent the medium from flowing back.
Core structure
Valve body and valve disc: The valve body is mostly made of stainless steel (such as 304, 316L), carbon steel or special alloys (such as titanium alloy, Hastelloy), the valve disc is a disc or plug-shaped structure, and the sealing surface is often welded with hard alloy (such as Stellite) to enhance wear resistance.
Guide device: The valve disc is connected to the valve cover through the valve stem to ensure the vertical movement trajectory and avoid eccentric wear.
Connection method: Flange connection (in accordance with GB/T 9112, ASME B16.5 standards) or clamp installation, suitable for horizontal pipeline layout.
Performance parameters
Nominal pressure: PN1.0~42.0MPa (up to Class 2500). Temperature range: -196℃~540℃, special materials (such as low-temperature steel) are required for low-temperature conditions. Applicable media: water, steam, oil, corrosive liquids (such as acids, alkalis), etc. Production and testing standards
Design specifications: API 594 (flange and wafer connection check valves), API 6D (general standard for pipeline valves). Sealing test: According to API 598 or GB/T 13927, leakage ≤0.01mL/min.
