Pressure Balance Valve

Basınç Denge Valfi

Pressure relief valve (specifically known as "cold room pressure regulation valve" or "pressure vent" in industrial cooling systems) is a mechanical safety and protection equipment

mounted on walls in cold storages, blast freezers, and industrial panel structures to equalize the pressure difference (vacuum or excessive expansion) between the room interior and the external environment. 

• Heater Resistance System: There is generally a low-wattage resistance heating element on the valve that operates at 220V. This resistance prevents the mechanical flaps of the valve from icing up and freezing due to extreme cold, which would make it inoperable.
• Dual-Directional Operation (Flap System): It has dual-sided opening flaps that allow air inside from the outside when a vacuum (low pressure) occurs, and discharges air from the inside out when the internal air expands during defrosting (high pressure).
• Minimum Thermal Loss: It opens momentarily only when a pressure difference occurs. As soon as the pressure is equalized, the flaps close tightly via a spring or weight mechanism, preventing unnecessary warm air entry and energy loss.
• Durable Body Structure: It is manufactured from rigid PVC plastic or stainless steel bodies compliant with hygiene standards, capable of withstanding harsh weather conditions between -40°C and +40°C.
• Adjustable Wall Thickness: It features a telescopic pipe structure that can extend or shorten to fit perfectly onto the panels according to the sandwich panel thickness (for example, from 60 mm to 200 mm).
