OSP pressure compensating safety valve is designed to balance the positive and negative pressure inside the silo. It is applied by taking air from the atmosphere during material discharge from the silo, and by opening the valve to give air to the outside in order not to damage the silo and the filter unit on the silo in case of possible pressure increases during silo filling. If it is blocked or not working, the filter unit and/or silo may be damaged, depending on the situation.

Scope of application
On silos, bunkers, containers and all areas where positive-negative pressure is not desired. It is used to prevent the silo and filter unit from being damaged together.

Materials:
All fittings are manufactured from carbon steel and can also be offered as stainless steel upon request. The valve cap is made of aluminum material, and the gasket material can be changed according to the application.
