Product Description
The Festo VZWM is a servo-controlled 2/2-way poppet solenoid valve with a diaphragm seal, designed for all-purpose use to control the flow of either air or water . Featuring a modular construction with an electrical connection via the solenoid armature tube and a wide range of separately orderable coils, this valve provides flexible integration for neutral liquid and gaseous media applications .
Key Features & Advantages:
Brass or Stainless Steel Casting Design: Available in robust cast brass (CRC 1) for standard applications or stainless steel casting for increased corrosion resistance, ensuring long service life in various media environments .
Electrical Connection via Solenoid Armature Tube: The valve features a standardized interface for solenoid coil mounting, allowing the coil to be ordered separately. This modular design supports a comprehensive range of coils with different voltages, simplifying maintenance and reducing inventory costs .
Diaphragm Valve Servo-Controlled: The indirectly actuated diaphragm design requires a minimum differential pressure (typically 0.5 bar) to operate, making it suitable for controlling high flow rates with relatively compact solenoids .
High Flow Performance: Delivers excellent flow rates with a standardized nominal flow rate up to 31,000 l/min for larger sizes (e.g., G2), ensuring efficient handling of water, air, and neutral fluids in high-volume systems .
Wide Application Range: Compatible with compressed air, inert gases, water, and neutral liquids; supports medium temperatures from -10°C to +60°C and a maximum operating pressure up to 10 bar (gaseous)/6 bar (liquid) .
