vertical lift check valve Description
Vertical lift check valve is an automatic valve specially designed for vertical pipelines. It controls the one-way flow of medium by lifting the valve disc along the vertical centerline of the valve body to prevent backflow. Its core function is to open and close by relying on the pressure of the medium itself or the weight of the valve disc, without external power.
Performance parameters
Nominal pressure: PN1.6~42.0MPa (such as H42H type is suitable for PN16~PN420). Applicable temperature: -29℃~550℃, chromium-molybdenum steel or special alloy materials are required for high temperature conditions. Applicable media: water, steam, oil, corrosive liquids, etc. Production standards
Design specifications: in accordance with API 6D (pipeline valves), GB/T 12235 (steel stop valves and lift check valves) standards. Testing standards: Sealing test according to API 598 or GB/T 13927, leakage rate ≤0.01mL/min
