Valve solenoid interlock KP

KP – Bolt Interlock with Safety Switch Mechanical Isolation The KP bolt interlock is a key operated mechanical bolt interlock complete with position monitoring electrical contacts for the control of electrical switchgear or valves. The KP lock comes with a 16 mm diameter bolt of variable length, that is used to control the rotation or movement of operating handles or toggles. The KP1 comes with 2N/C 1N/O 10 amp contacts and the KP2 has 4N/C 2N/O 10 amp contacts, these are used to provide remote indication of the bolt position or to switch the control circuitry on the machine. The locks are manufactured in brass or stainless steel. OPERATION The Castell KP bolt interlock with safety switches is used in switchgear control to break circuitry and inhibit movement of cams, toggles or levers simultaneously. The KP bolt interlock is available as a KP1 or KP2 version with either one or two safety switches respectively. The KP bolt interlock is available with as rear or front entry mounted switch (panel or surface mount respectively). The length of the bolt is available in various lengths to suit the application, but the travel of the bolt is always 19.05 mm. The key is trapped when the bolt is extended. Rotation of the key anti clockwise will retract the bolt and change contacts in the switch. USAGE The KP bolt interlock with safety switch should be used to allow safe control of valves or disconnect switches. The KP bolt interlock is not designed for security purposes, such as access to a building. APPLICATION KP bolt interlock safety component with safety switches are used as part of an integrated safety system, typically in switchgear applications.
