Single Flange Pneumatic Powder Butterfly Valve Aluminum Alloy Dust Butterfly Valve with Limit Switch for Cement Silo Discharge
Made of high-strength die-cast aluminum alloy valve body, the valve disc adopts wear-resistant orange PU coating, which achieves excellent sealing effect, effectively avoiding powder leakage and medium backflow in bulk material conveying pipelines.
Adopts standard double flange connection structure, complies with BV2F series installation dimensions from DN100 to DN400, easy to install between pipelines, stable connection and strong pressure resistance.
Equipped with high-efficiency double-acting pneumatic actuator and transparent limit switch, it can quickly open and close the valve and remotely feed back switch status signals to realize automatic pipeline control.
Widely applied to cement silos, concrete mixing stations, grain warehouses, plastic particle transportation, dust ventilation and other working conditions, suitable for conventional low-pressure bulk material conveying systems.
Modular split design facilitates daily disassembly, cleaning and replacement of wearing parts. Each valve undergoes strict air tightness testing before delivery to ensure stable long-term operation.
