Product Description
The Festo VZ and VZO series are pneumatic time delay valves forming part of the M5 Compact System, a complete offering of control components with all functions required for pneumatic sequence control . Designed specifically for control cabinet installation, these 3/2-way normally open valves deliver an adjustable delay time of 0.25 to 5 seconds, enabling controlled pneumatic switching for simple automation tasks without electrical components .
Key Features & Advantages:
Complete Pneumatic Sequence Control System: Part of a comprehensive system providing all necessary components for pneumatic sequence controls, including logic valves and timers, enabling purely pneumatic automation without electrical controls .
Adjustable Delay Time (0.25–5s): Features an infinitely adjustable time delay of 0.25 to 5 seconds using a built-in throttle restriction mechanism, allowing precise timing control for sequential pneumatic operations .
Control Cabinet Optimized Design: Specifically engineered for control cabinet installation with 2n mounting frame compatibility, featuring fast component replacement for efficient maintenance and system modification .
3/2 Normally Open Function: Monostable 3/2-way valve with mechanical spring return remains open in its resting state, switching to a closed position after the set delay time when the pilot signal is applied .
Barbed Fitting Connections (PK-3): PK-3 barbed fittings for 3 mm OD plastic tubing provide secure, leak-free pneumatic connections that simplify installation without separate fittings .
