China solenoid valve AC 110V Manufacturer, Supplier, Factory

This pneumatic combination switch is available in configurations controlling one to six compartments, suitable for centralized control of pneumatic valves in oil tankers. It includes control for bottom valves, vapor recovery valves, side panel ventilation valves, pipeline control valves, and unloading valves, enabling quick opening and closing and remote control to ensure safe and reliable loading and unloading operations.

Valves are the primary Pneumatic Control Components that control the direction, flow rate, and pressure of air.
