Product Description
The Festo VAPB series offers high-quality ball valve solutions with full flow for use in industrial applications, available in brass (-MS) or stainless steel (-CR) for increased corrosion resistance . This automatable 2/2-way valve features a blow-out proof shaft, can be operated manually via hand lever, and is designed for in-line installation with mounting flange to ISO 5211 for actuator automation .
Key Features & Advantages:
Automatable 2-Way Ball Valve: 2/2-way valve function designed for automation, featuring an ISO 5211 mounting flange that allows easy integration of pneumatic or electric rotary actuators for remote operation .
Brass or Stainless Steel Construction: Available in nickel-plated brass (-MS) for standard applications or stainless steel (-CR) for increased corrosion resistance in aggressive environments .
Blow-Out Proof Shaft Design: Safety feature prevents the shaft from being blown out under high pressure, ensuring reliable operation and preventing hazardous media release .
Manual Operation via Hand Lever: Convenient manual override capability allows operation using the hand lever during commissioning, maintenance, or power outages, with slot direction indicating flow position .
Wide Media Compatibility & Temperature Range: Suitable for compressed air, inert gases, water, and neutral liquids, with medium temperature range from -20°C to +150°C and nominal pressure ratings of PN25 or PN40 .
