Producers of bus pneumatic folding door accessories
Product Description
Ensure the safety, reliability, and efficiency of your bus fleet’s access systems with the Universal Model 803 Solenoid Valve, engineered specifically for out-swing door pumps. This critical component is the heart of the door control mechanism, providing the swift and precise actuation needed for modern transit operations.
The Model 803 solenoid valve is designed for wide compatibility, making it an ideal and cost-effective replacement part for a diverse range of bus makes and models. It expertly converts electrical signals into pneumatic force, allowing for the smooth, rapid, and consistent operation of the out-swing doors. This enhances passenger flow, minimizes dwell times at stops, and, most importantly, guarantees passenger safety. Built to withstand the rigors of constant daily use, its robust construction ensures exceptional durability, resistance to vibration, and a long, maintenance-free service life.
This premium component is proudly manufactured by Nanjing Dingguan Auto Parts Co., Ltd. As the direct manufacturer, we maintain complete control over the production process, from sourcing high-grade raw materials to implementing rigorous final testing.
