VOFC

Product catalog summary

Overview: This document outlines the technical specifications and ordering details for Festo's VOFC series solenoid valves, designed for process automation in chemical and petrochemical environments. These valves are built for harsh conditions and outdoor use.

Specifications: The VOFC series includes 3/2-way and 5/2-way valves, available in single or double solenoid configurations. They feature a piston spool or poppet valve design with Ematal-coated aluminium housing for durability. Compatible with AC and DC voltages, these valves are CE marked for ATEX compliance and meet ISO 8573-1:2010 [7:2:2] standards with IP65 protection.

Functionality: These pilot-actuated valves can switch between internal and external pilot air, suitable for vacuum applications, and have a NAMUR connection pattern for direct actuator mounting. They offer manual override options and various connection types, including G1/4, G1/2, and NPT threads.

Technical Data: Operating within a temperature range of -25 to 60°C and a pressure range of 2.5 to 8 bar, the valves have a flow rate of 913 to 1030 l/min. They are designed for non-reversible flow direction, compliant with SIL2 safety integrity levels, and have a corrosion resistance class of CRC 4.

Materials: The valves are constructed with Ematal-coated aluminium housing and NBR seals, compliant with RoHS standards, though they may affect paint-wetting.

Accessories: Available accessories include throttle plates, sub-bases, mounting plates, connection sets, adapters with filters, and exhaust protection, enhancing valve functionality and installation flexibility.

Ordering Information: The document provides part numbers and type codes for various VOFC valve configurations, allowing customization via an online configurator. Type codes specify valve series, design principle, function, pilot air method, and other specifications.

Dimensions: Detailed dimensions for each valve configuration are provided, including options for manual override and various connection interfaces. CAD data is available for download from the Festo website.

Applications: Suitable for high corrosion stress applications, such as outdoor exposure or industries dealing with aggressive media like chemicals or food. Special tests may be required according to Festo standards.

Characteristics General • The valves of series VOFC are special 3/2-way and 5/2-way valves for process automation and applications in chemical and petrochemical installations, where they are frequently used as pilot valves for butterfly valves and actuators. Their sturdy design and high resistance to corrosion make these valves suitable for outdoor use under harsh ambient conditions. • With the flange pattern to NAMUR, the solenoid valves are particularly suitable for quarter turn actuators. The integrated spring chamber re-breather function protects quarter-turn actuators with spring return...
