Product Description
The Festo VZBA is an automatable 2-way or 3-way ball valve made from high-alloy stainless steel for trouble-free control of aggressive media or gases in piping systems . This 2/2-way valve features a blow-out proof shaft for safety under high pressure and allows manual operation via hand lever. It is designed with connecting thread to EN 10226-1 and a mounting flange to ISO 5211, meeting the requirements for installation in ATEX zones 1, 21, 2, and 22 .
Key Features & Advantages:
Automatable 2-Way or 3-Way Ball Valve: The 2/2-way configuration is ideal for on/off flow control; the valve can be equipped with pneumatic or electric quarter-turn actuators for remote automation with a 90° swivel movement, ensuring reliable shut-off in both directions .
Stainless Steel Design: The 高合金不锈钢 housing (material 1.4408), ball, and shaft provide excellent durability, high corrosion resistance class (CRC 3), and compatibility with aggressive media like acids, gases, chemicals, water, and oil .
Blow-Out Proof Shaft: The stem is designed with retention features to prevent the shaft from being forcibly ejected under high pressure, enhancing operational safety and preventing media blow-out .
Manual Operation Using Hand Lever: Allows for safe and easy manual valve actuation during commissioning or maintenance, eliminating the need for a power supply. The lever slot orientation indicates flow position clearly .
High Safety and Media Compatibility: Features a soft sealing principle (FPM or PTFE) with a nominal pressure rating of PN63, allowing a wide operating temperature range from -10°C to 200°C and compatibility with compressed air, inert gases, water, and neutral liquids .
