Blow-through valve type B70

TYPE B70 = TWO TIMES TYPE B35 INLINE WITH THE SAME SPECIFICATIONS.

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 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 in line.
Compact dimensions with ample volume, achieved through small installation sizes resulting from a short inlet hole and narrow installation width.

*ADDITIONAL SPECIFICATIONS:

Type B70 features external bearings.
Type B70 has a scraper blade on the rotor to prevent hygroscopic products from accumulating on the wall (image on the right).
A wiper on the rotor prevents the rotor chamber from being filled 100% and prevents hard materials from jamming between the rotor and the stator (image on the left).
Type B70 has two vent holes and double product volume with an identical blow-through connection.
Type B70 has a wider inlet hole, but remains compact with two inline hydraulic motors.
