Product Description
The Festo VZWD is a directly controlled 2/2-way poppet solenoid valve designed for high-pressure applications up to 90 bar, operating reliably without differential pressure even in closed media circuits . This 2/2 normally closed, monostatic valve is ideal for high-pressure and dosing applications with low flow rates, featuring a soft sealing principle and in-line installation.
Key Features & Advantages:
No Differential Pressure Required: Operates reliably from 0 bar up to 90 bar without requiring any pressure difference across the valve, making it perfect for closed media circuits and vacuum applications where differential pressure may be zero .
High Pressure Range (0–90 bar): Engineered for demanding high-pressure environments with nominal pressure ratings from 4 bar up to 90 bar, suitable for water, mineral oil, neutral liquids, inert gases, and compressed air media .
Directly Actuated Poppet Function: Direct-acting poppet valve design with mechanical spring reset provides immediate response without pilot requirements, delivering precise control with switching times as fast as 18-25 ms .
Versatile Material & Connection Options: Available with brass (CW614N) housing for standard applications (CRC 1) or high-alloy stainless steel (1.4305) for increased corrosion resistance (CRC 3), with G-thread or NPT connection options in sizes G1/8, G1/4, or NPT1/8 .
Compact Design with IP65 Protection: Compact solenoid design with electrical connection via rectangular plug to EN 175301-803 (Type A, 3-pin) and IP65 degree of protection .
