Festo VSNC pilot valve

Widely used for distributed control systems, NAMUR-style pilot valves can be found in a variety of industries, including chemical, pharmaceutical, water/wastewater and food processing.

The VSNC pilot valve can be easily adapted for use with either a single-acting or a double-acting actuator. Simply turning the seal around 180° converts a 5/2-way valve into a 3/2-way valve. In the case of the 3/2-way function, exhaust air is fed via the seal into the spring chamber of the actuator. This protects the spring chamber from contaminated ambient air and ensures a longer service life for the pneumatic actuator.

In addition to the standard coil range, an IEC-EX certified solenoid system provides protection against potentially explosive environments. The design of the VSNC means that any of the coils, even with different types of protection, can be mounted on a robust stainless steel armature tube, allowing versatile applications.

Preassembled valves that reduce time and effort for tubing and assembly offer added convenience. The simplicity of the pilot valve starts with a user-oriented modular system for ease of ordering. A compact and practical range of accessories, including flow control and quick exhaust valves, is also available.
