Bulk flow has to be distributed an collected. For that diverter valves with the highest demand on functionality and operational safety are used. For product pureness deposit-free and CIP capable diverter valves are indispensable.
Their maintenance-free operation is a deciding factor for the profitability of the plant. Diverter valves from Coperion Waeschle fulfil these numerous requirements even at high pressure and temperature ranges.

Quik-Vent™
Vacuum/Pressure Relief Valve
Series 684
Controls unsafe pressure conditions
The Quik-Vent vacuum / pressure relief valve is an excellent safety device for mounting on storage silos, bins or any other container to relieve excessive or unwanted air pressure that might be generated by a pneumatic conveying system or other process equipment.
Unsafe conditions are easily controlled by the Quik-Vent vacuum/pressure relief valve. Generous ports quickly exhaust air or gases to protect against sudden positive or negative pressure conditions.
Optional sensors are also available to provide an electrical signal to indicate when over or under pressure conditions are present.

If controlled feeding from or into silos and hoppers in a very confined space is required Rotary Valves are the ideal solution.
The sealing of negative pressure cyclone and dust filter outlets is the other classic application.
RVS-type Blow-Through Rotary Valves have been developed in accordance with the criterion of maximum scope in application.
They have been designed for the controlled discharging of powders or granular materials from silos, bins, hoppers, cyclones or dust collectors into low- and medium-pressure pneumatic conveying lines.

Rotary Airlocks - Standard Rotary Valves
The prime function of a rotary valve is to regulate the flow from one chamber to another while maintaining a good airlock condition. The product is mainly in dry powder or granular form.
In the dust filtration field good airlocks are essential on cyclone and bag filter application in order that the manufactures quoted high dust collection efficiencies can be maintained. Airlocks are also important in the pneumatic conveying industry, where product is regulated into a high pressure conveying line while minimising air leakage.
With Rotolok there are no double standards, all our standard valves are precision machined for close tolerances and minimal eccentricities Pressure differentials to 20psi and temperatures to 400°C.
Extreme Pressures and Temperatures can be accommodated with special designs, if your application requires such considerations contact Rotolok Engineering team.
