DN80 Aluminum Alloy Ball Valves
The DN50 Aluminum Alloy Ball Valve is a lightweight ball valve configuration documented with manual and/or pneumatic actuation options depending on the model. The valve uses a preloaded Belleville seal seat designed to maintain sealing pressure and compensate for seal-face wear and changes in temperature and pressure.

Application Positioning
The DN80 manual aluminum alloy ball valve is suited to fluid-isolation applications requiring DN80 nominal diameter, 1.0 MPa working pressure and −40°C to +80°C temperature capability. Its documented differentiators are the preloaded Belleville seal seat, double sealing, fluorosilicone seals, automatic valve-cavity pressure relief and aluminum-alloy construction.
Engineering Selling Points
Preloaded Belleville Seal Seat - The spring-preloaded seat maintains sealing force and is designed to compensate automatically for seal-face wear and changes in temperature and pressure.
Double Sealing at Inlet and Outlet - Sealing is provided at both inlet and outlet sides, providing a defined sealing barrier at both flow connections.
Fluorosilicone Rubber Seals - The specified fluorosilicone rubber seals are identified in the catalogue as oil-resistant and aging-resistant; compatibility should be verified against the actual service medium.
Automatic Valve-Cavity Pressure Relief - The valve is designed to automatically relieve abnormal pressure buildup inside the valve cavity.
Aluminum Alloy Construction - The DN80 valve uses an aluminum-alloy body. The catalogue describes the valve as lightweight and flexible in operation.
−40°C to +80°C Operating Range - The documented temperature range provides a clear basis for checking the valve against the installation's ambient and process-temperature envelope.
1.0 MPa Working Pressure - The documented working pressure is 1.0 MPa and should be checked against actual design pressure, operating pressure and transients before selection.
