Product Description
The Festo VZWD-B is a directly controlled 2/2-way poppet solenoid valve designed as the optimal solution for high-pressure and dosing applications up to 100 bar, operating reliably without differential pressure even in closed media circuits . This 2/2 normally closed monostable valve features a large pressure range for flexible applications, a high medium temperature range up to 140°C, and is suitable for use in vacuum technology.
Key Features & Advantages:
Large Pressure Range for Flexible Applications: Operates reliably from 0 bar to 100 bar maximum operating pressure without requiring differential pressure, making it ideal for closed media circuits, high-pressure systems, and vacuum applications down to 100 mbar .
Reliable, Directly Actuated Poppet Valve: Direct-acting poppet valve design with mechanical spring reset provides immediate response without pilot ports, offering operation unimpaired by light levels of dirt and integrated normally closed safety function that closes automatically in cases of pressure loss .
High Temperature Range of Medium up to 140°C: Engineered for demanding high-temperature applications with medium temperature capability up to 140°C, significantly higher than standard valve ranges, supporting hot water, steam, and high-temperature fluid handling.
Versatile Use Including Vacuum Technology: Suitable for both high-pressure systems up to 100 bar and vacuum systems down to 100 mbar, providing a single-valve solution for applications requiring both pressure extremes .
Robust Construction for Aggressive Media: Available with brass (CW614N) or high-alloy stainless steel bodies with FPM seals, providing corrosion resistance class CRC 1 (brass) or CRC 3 (stainless steel) for compatibility with water, air, neutral media, and slightly aggressive fluids .
