Notes:
1. Connection dimensions and pressure ratings can be customized.
2. Valves ≤ DN500 are typically manual; valves ≥ DN500 are generally hydraulic. Actuation type is configurable—hydraulic models are identified with a suffix "Y".
3. This table lists standard valves up to DN1000. Larger sizes are available upon request.
