TiNi™ Cryogenic Valve

Operable at Pressures up to 10,000 psi

The EBAD TiNi™ Cryogenic Valve uses a high force piston that is operable at pressures up to 10,000 psi. This may be configured in either a “Normally Open” or “Normally Closed” embodiment. The sealing mechanism is designed to operate with both gas or liquid at temperatures down to -200 degrees Celsius.


NEA® (Non-Explosive Actuators) – As with all EBAD products, the Valve is non-pyrotechnic and field reset-able with a minimum qualified life of 10 cycles.

Field Reset-able and Reliable – The Valve is reset by simply re-cocking the piston that drives it using the specially tool provided.  This may be done while the Valve remains fully attached to supporting structure and plumbing.

Redundant Firing Circuit – As with all EBAD Actuators a redundant SMA circuit is incorporated. This provides complete electrical redundancy as well as mechanical redundancy for the critical trigger element.

Fast Acting – By directly passing current through the SMA element, EBAD Valves perform in millisecond time frame making them ideal in critical flow applications.

Auto Shut-Off Switches – Simple Auto Shut Off Switches are incorporated into each Valve to protect the Trigger.  This makes them very “user friendly” and operable from a wide range of current and voltages.

Cryogenic Valve Options

The NOV-4387 Valve is a “Normally Open” configuration valve that can be used to shut off high pressure flow on command.   Inlet and Outlet tubes and attachment method are customizable as is the flow direction (inline as shown or orthogonal).  As with all EBAD  products, key attributes include:

Reset Tools

The EBAD Mini Frangibolt® Actuator is rated to have a minimum life of 50 cycles. For continued testing and preparation for final installation, EBAD provides a mechanical reset tool as shown which will generate the force and stroke required to compress all Mini Frangibolt® Actuator styles.

Compression of the Mini Frangibolt® Actuator is a simple 3 step process: First, install the unit in the fixture using the adapter provided. Second, tighten the drive screw using a torque wrench until the specified torque value as indicated on the reset tool has been reached.  Third back off the drive screw and remove the actuator.  The whole process may be carried out in less than 30 seconds. Furthermore, the size and weight of the Mini Frangibolt® Actuator Compression Fixture make it fully portable allowing easy transport.
