Functional principle of the overload safety device Conical safety pin positioned in a matching guide. Precisely defined release force. Self locking principle. When the valve pin movement is blocked and the defined maximum permissible pressure load is reached the safety pin is pushed out of the guide. The valve pin is detached and uncoupled from the movement of the synchronous plate. Normal operation NEW! Enhanced operational safety Overload safety device for valve gate systems with synchronous plate actuation Synchronous plate position: valve pin open Synchronous plate position: valve pin closed Overload safety device triggered • Prevents damage to the valve pin caused for example when a gate is blocked by impurities in the melt • No cost-intensive maintenance work Safety pin has been pushed out of the guide. Valve pin is uncoupled from the movement of the synchronous plate. No damage to the valve pin • Available as an option for all new moulds which feature a valve gate system with synchronous plate actuation and a valve pin diameter of 2 mm • Patent pending technology EWIKON Heißkanalsysteme GmbH Siegener Straße 35 • 35066 Frankenberg • Tel: +49 6451 501-0 Fax: +49 6451 501-202 • E-Mail: [email protected] • www.ewikon.com Technical information subject to alteration
