Product Description
The Festo PZVT is a pneumatic timer designed for realizing switching delays in pneumatic sequence control systems, featuring a setting screw and visual indicator for precise adjustment . Part of a complete system offering all control components required for pneumatic sequence control, this timer is engineered for control cabinet installation with fast component replacement . The mechanical sequence counter with pneumatic drive switches the input pressure at port 1 through to port 2 after the preset delay time has expired .
Key Features & Advantages:
-
Adjustable Delay Time with Visual Indicator: Features a setting screw for precise adjustment across various delay ranges (0.2–3s, 2–30s, 8–120s, 20–300s) with a visual indicator confirming the set time, enabling accurate timing control for pneumatic circuits .
-
Mechanical Pneumatic Drive – No Electrical Power Required: Operates purely on compressed air, consuming energy only during switching with very low power consumption, making it ideal for hazardous areas and applications where electrical components are restricted .
-
Fast Component Replacement: Engineered for rapid exchange without significant system disruption, minimizing downtime during maintenance or system modifications .
-
Front Panel Mounting with IP54 Protection: Designed for control cabinet integration with front panel mounting and IP54 protection when used with protective cap and panel frame, ensuring durability in industrial environments .
-
ATEX Hazardous Location Certified: Suitable for use in ATEX Zone 1, 2, 21, and 22 explosive atmospheres, making it ideal for environments where flammable gases or dust may be present .
