Mechanical Flow Restrictor

Product TypeEquipment enables velocity control of valve pin opening for hydraulic valve gate hot runner systems.

1. Valve Gate Hot Runner SystemHydraulic valve gate hot runner system for nozzle series 12E, 16E, 22E with conical valve gate.

a) Hydraulic actuator

2. Mechanical Flow Controlb) Connection boxc) Signal lined) Monitoring unite) Hydraulic valve block

The components b - d omitted when using the hydraulic actuator series HB4008 without limit switches (see page 2).

Operation Principle, Application, Benefits ♦ Manual adjustment of a velocity-

regulated opening stroke of the valve gate pin for each zone.

Areas of Application ♦ Optimizing of the surface quality of

sequential or cascade injection molding.

Attention:Customer to provide cascade control signals.

Actuator HB2508, HB4016 Series

Available VersionsHB2508, HB4016

Product DescriptionThe HB Hydraulic Actuator series and PB Pneumatic Actuator series is bolted to the manifold.Each Actuator is available with optional Ther-mocouple (TC) and patent pending Position Sensor (PS).The Position Sensor detects pin position and sends a signal to activeGate™ products providing closed loop position control or pin position indication and speed monitoring with Valve Monitoring Interface (VMI).

All HB series actuators are provided with the following features:

♦ Automatic bleed for air removal in Hydraulic lines to provide consistent actuation

♦ Easy Valve Pin adjustment through cutout in top clamp plate

♦ Valve Pin quick coupling ♦ Valve Pin anti-rotation feature
