Blow-through valve type B20

Robust construction achieved through the use of high-quality cast iron GG25.
The large central shaft made of premium steel ensures minimal deflection due to high top-loading, minimal deflection from blowing under pressure and also serves as a solid foundation for welded components.
The bearings are maintenance-free with a service life of 12 years (at 0.5 bar, 40°C, and 30 RPM).
The seals provide maximum protection.
The valves are water- and weather-resistant, capable of withstanding high-pressure cleaning, road debris, salt and operating temperatures ranging from -15°C to 60°C.
The valves are designed for rebuilding.

Compact built-in dimensions and intelligent geometry ensure smooth product flow.
The V-shaped inlet allows for a large inflow volume and the sloping cutting edge facilitates smooth product movement (not applicable to Type B35 and Type B70).
The semi-underlying blowing chute maintains a constant, uninterrupted airflow, reducing the likelihood of blockage during overload or material transportation.
The large central shaft ensures maximum sealing between chambers.

Various drive options: external motor, chain-driven or inline motor equipped with a coupling (Type B35 and Type B70 = external motor in line.
Compact dimensions with ample volume, achieved through small installation sizes resulting from a short inlet hole and narrow installation width.
