TiNi’s 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.
TiNi Cryogenic Valve offers the following advantages:
NEA (Non-Explosive Actuators) – As with all TiNi 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 TiNi Actuators a redundant SMA circuit is incorporated. This provides complete electrical redundancy as well as mechanical redundancy for the critical TiNi trigger element.
Fast Acting – By directly passing current through the SMA element, TiNi 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 TiNi Trigger. This makes them very “user friendly” and operable from a wide range of current and voltages.
