DN25 Aluminum Alloy Ball Valves
The DN25 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.

Pneumatic Actuation
For the documented pneumatic models, the control air pressure is 0.4 MPa. The single-acting version opens when Port A is pressurized and closes automatically when Port A is exhausted. The double-acting version uses separate air control through Port A for opening and Port B for closing.
