PIN-TECH Series 56000 Pressure Relief Vent

Brand: Protectoseal Company

Series 56000, PIN-TECH Pressure Relief Vents are designed and tested to address concerns about the leakage of fugitive emissions prior to set point. 

PIN-TECH vents are mounted to the vapor space flange connection of a storage tank or vessel. 

The vents utilize a unique technology that employs a buckling pin to hold the vent piston closed with less than 500 ppm leakage up to the relief set point. 

The pin is an accurately machined, straight metal rod. 

The force required to buckle the pin is governed by Euler’s Law and is a function of the pin’s metallurgy, length and diameter. 

When the pressure in the tank reaches the vent set point, the axial force is sufficient to buckle the pin and the vent sealing piston is allowed to move to its full open, relieving position. 

The pin buckles completely and instantaneously.
