Rupture Pin Technology

The Model A Relief valve senses line pressure and holds a bubble-tight, closed position until pressure reaches an exact set point. At set point, the safety pressure relief valve instantly opens to relieve pressure from a protected system and vents to the atmosphere.

The Model D is an inline body safety pressure relief valve that holds a bubble-tight, closed position until pressure reaches an exact set point. At set point, the valve instantly opens to relieve pressure from a protected system.

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.

The Model HPRV is an angle body valve that holds a bubble-tight, closed position until pressure reaches an exact set point. At an exact set point, the pin buckles and the valve opens in milliseconds for immediate pressure relief. Relieves pressure to prevent pump, hose and system damage on frac fluid systems – ideal for pulsating pressure.

The Model IC is an angle body valve that holds a bubble-tight, closed position until pressure reaches an exact set point. At set point, the pin buckles and the valve opens in milliseconds for immediate pressure relief to prevent pump, hose and system damage on mud and slurry pump systems – ideal for pulsating pressure.

The Model C-M is an angle valve that holds a bubble-tight, closed position until pressure reaches an exact set point. At set point, the valve instantly opens to relieve pressure from a protected system.
