VZWF

Product catalog summary

Overview: This document outlines the technical specifications and ordering details for Festo's VZWF solenoid valves, which are force pilot operated and designed for various automation tasks. These valves are known for their quick delivery and high quality.

Key Features: The VZWF solenoid valves are normally closed and feature a diaphragm with a forced lifting mechanism. They operate without differential pressure between the inlet and outlet, making them ideal for applications such as cooling, filling systems, vacuum, and liquid gas handling. They come with different sealing materials and can handle pressures starting from 0 bar.

Technical Specifications: The valves have connecting threads ranging from G1/4 to G2, with flow rates (Kv) between 1.8 to 28 m3/h. They are designed for in-line installation with electrical actuation and no manual override. The valves feature a soft sealing principle and are not reversible in flow direction. They are protected to IP65 standards and can handle a maximum viscosity of 22 mm2/s.

Materials and Construction: Valve bodies are made from cast brass or stainless steel, with high-alloy stainless steel screws. Seals are available in NBR, FPM, and EPDM. The materials comply with RoHS standards and may contain substances that impair paint wetting.

Electrical Data: The valves support electrical connections conforming to EN 175301-803 type A, and are compatible with direct current (24 V DC) and alternating current (110 V AC/230 V AC) with permissible voltage fluctuations of ±10%.

Ordering Information: Detailed part numbers are provided for ordering valves with different body connections and materials, including options for brass or stainless steel housings, and various sealant and voltage configurations.

Applications and Recommendations: These valves are suitable for environments with high corrosion stress and moderate corrosive conditions, designed for outdoor exposure and industrial environments. Specific recommendations are provided for flow direction and pressure conditions.

Product Specifications: The document lists various product codes for the VZWF-L-M22C-G2-500 series, each representing a specific model with unique features.

Contact Details: Festo provides contact information for ordering and customer service in Canada, Mexico, and the USA, including phone numbers and email addresses. A Customer Interaction Center and a Multinational Contact Center are available for support.

Additional Information: The document notes that information is subject to change, indicating that specifications and contact details may be updated over time.

Solenoid valves VZWF, force pilot operated Normally closed solenoid valve with diaphragm and forced lifting. When the solenoid is energised, the differential pressure from the secondary side of General -O- Connecting thread the diaphragm is reduced via an internal pilot hole. The effective differential pressure lifts the diaphragm away from the valve seat. If Application • Suitable for closed applications such as cooling or filling systems • Vacuum • Liquid gas • Filling systems there is no differential pressure, the diaphragm is lifted directly by the solenoid.
