Model A Isolation

Rupture Pin Model A ESV Valve

Model A Isolation

The Model A is an angle body valve that holds a bubble-tight, open position until flowing pressure acting on the unbalanced stem area puts an axial force on the pin. At set point, the pin buckles and the valve closes for a bubble-tight seal. In case of a downstream line break, the mass velocity impinging on the lower piston surface will force the pin to buckle and the valve will seal closed. Unlike conventional valves and rupture discs, the Model “A” proves it is environmentally friendly by keeping you from flaring production or venting production to the atmosphere.
