Pneumatic cartridge valves machined into your product provide airtight locking, so that in the event of a pressure drop or a total loss of pressure, position and load holding capabilities are maintained. Air flows freely from input to output, but will immediately lock if the flow reverses direction or stops. The cartridge can be changed in less than 2 minutes. Flow control, manual release, and adjustable closing speed options, are available.
