The TEC spring loaded pressure relief valve offers reliable capacity relief for positive displacement blowers. 

The pressure relief valve is installed in the discharge air stream to prevent damage to positive displacement blowers when operating pressure exceed the maximum pressure rating of the blower.

As the system pressure approaches the valve set point, the valve is forced up from the valve seat for fast and efficient blow-down. When acceptable system pressures are restored, the valve automatically returns to the original set position.

The valve body is constructed of cast iron and accurately machined to very tight tolerances for a tight seat and smooth operation.

The valve is fully adjustable to permit accurate pressure settings. Adjustment in the relief valve setting can be made by changing the compression of the spring.
