Festo Corporation has introduced the HE-U, the first model in a series of in-line compressed air lockout valves for use in the control of hazardous energy.
Manually operated, the HE-U allows interruption of a compressed air supply to pneumatic machinery whilst service or maintenance is performed.
The HE-U also allows venting of residual downstream pressure and is ported for either 3/8″, 1/2″, 3/4″ and 1″ connections (NPT or BSP threads).
Design characteristics include engineered seals that, claim Festo, provide long life in hostile environments.
Festo also claims that the valve’s flow paths have been optimised by careful spool design, and the 1″ exhaust port facilitates rapid-rate depressurisation of downstream residual while the valve is closed.
