It regulates the flow of concrete by opening, closing, or partially obstructing the passageway, ensuring precise delivery and preventing overflows or blockages.
The operating pressure range is 1.0–1.6 MPa, and the operating temperature range is -20 to 80 °C. These are reference values; confirm with the manufacturer for your specific model.
It can be actuated manually, hydraulically, or pneumatically. For automated control, a 4–20 mA signal is used, and actuation time typically ranges from 5 to 30 seconds.
Relevant standards include ISO 6708 for nominal diameter, ISO 5208 for pressure and leakage, IEC 60381 for control signal, IEC 60529 for enclosure protection, and ASTM A216/A351 for body material. These are references for verification, not proof of compliance.
