FAQ

What is the difference between H44F and H41F check valves?
H44F is a swing type check valve; H41F is a lift type. Swing is used in horizontal pipelines, while lift is suitable for both horizontal and vertical.

Which pressure ratings are supported by these check valves?
This series supports pressure classes PN1.0MPa and PN1.6MPa, covering most industrial and chemical pipeline systems.

What are the compatible media types for these valves?
They are ideal for water, steam, gas, and corrosive fluids when selected with appropriate materials like CF8M or lined with F46.

Can I install this valve vertically?
Yes, both types support vertical installation. Lift type (H41F) is better suited for vertical use with upward flow.

Are these valves compliant with international standards?
Yes, they meet GB12236, GB12221, JB/T924.1, and API/ASME equivalent flange and test standards.
