The TEC weight loaded pressure relief valve offers non-vibrating, 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 weight loaded cylinder is forced up from the valve seat and exposes the vent ports for fast and efficient blow-down. When acceptable system pressures are restored, the valve automatically returns to the original set position.

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

Removable weight have been carefully designed to permit accurate pressure settings in 0.5PSI increments.

Adjustments in the relief setting can be made by adding or removing weights.
