PRESSURE REFIEF VALVES

VHS pressure relief valves regulate pressure inside the silo in case of a sudden increase or decrease. Installed on silos, hoppers in flour mills, bakeries for the storage of flour; chemical, construction industries for the storage of dry mixes. During normal operation of the silo valve does not work.

DESCRIPTION OF THE PRESSURE RELIEF VALVE VHS

Metal cylindrical body of the valve is mounted on the roof of the silo and connected to the exhaust pipe with pipeline. An elastic diaphragm is installed inside the body, which reacts instantly to the pressure change inside. A set of counterweights keep the valve closed at normal pressure.

 

Principle of operation:

VHS valves react quickly to changes in pressure inside the silo. Through the interaction of pressures on different surfaces on both sides of the diaphragm installed inside the valve body, pressure balancing is achieved. At overpressure, air goes out to the external atmosphere. In case of pressure decrease, air from outside enters the silo.

AISI 304 stainless steel body;
case diameter 273 mm;
air capacity up to 5000 m3 / h;
exhaust pipe for connection with the central aspirarion system;
these valves are designed for a negative maximum pressure of -0.005 bar and a maximum pressure of + 0.05 bar.
– non-standard options are available;
– inductive sensor;
– protective net;
– adjustment kit.
