Product Description
The Festo VZBC is an automatable 2/2-way compact flanged ball valve made from stainless steel for controlling media in piping systems with full flow in both directions. This high-quality valve features a short installation length, blow-out proof shaft for safe high-pressure operation, and manual override via hand lever, designed for in-line installation with flanges to DIN 1092-1 and ISO 5211 for actuator automation.
Key Features & Advantages:
Stainless Steel Compact Flange Design: Constructed from high-alloy stainless steel (1.4408), providing excellent corrosion resistance (CRC 3 – high corrosion stress) and suitability for aggressive media, gases, water, and neutral liquids.
Blow-Out Proof Shaft: Safety retention feature prevents the shaft from being forcibly ejected under high pressure, ensuring reliable operation and preventing hazardous media release.
Manual Operation via Hand Lever: Convenient manual override capability allows safe valve actuation during commissioning and maintenance without power supply, with lever slot orientation clearly indicating flow position.
Short Installation Length: Its compact flange design with reduced face-to-face dimensions simplifies installation in tight pipework layouts, lowering system costs and weight.
High Safety and Media Compatibility: Features PTFE soft sealing with a nominal pressure rating of PN16 to PN63, a wide operating temperature range from -10°C to 200°C, and full flow in both directions (reversible flow).
