Spool Monitored Hydraulic Blocking Valve for Injection Blow Molding Machines

The blocking spool is monitored for correct positioning when one or both of the access doors are opened and closed. Should the spool not move to the "blocked" position when an access door is opened, an electrical signal is sent to the control outputs and shuts off the hydraulic pump motor preventing further clamp movement. This condition will present an alarm indication and will not permit restarting of the hydraulic pump until the hydraulic safety valve is functioning properly. Includes:
