The manual push-pull valve is a compact and efficient component used in pneumatic control systems on fuel and chemical tankers. It provides manual air flow control for critical functions such as emergency shut-off activation, making it an essential part of safe loading and unloading operations.

This valve operates reliably in challenging environments, supporting a maximum working pressure of 16 bar and an airflow rate of up to 300 L/min. Designed for temperatures ranging from -25°C to 60°C, it ensures dependable operation in both cold and hot conditions. It also features a handbrake interlock function, which cuts power to the equipment if the valve remains engaged, adding an extra layer of operational safety.
