Festo introduces the standard NAMUR valve VSNC, certified worldwide in
accordance with the relevant explosion protection standards.
The standard NAMUR valve VSNC finds versatile application in diverse industry
segments and features a modern design, durable quality and fully tested
technology and materials.
Designed to deliver an attractive price/performance ratio, the new NAMUR
valves from Festo can efficiently and reliably control the flow of a wide range
of media in different ambient conditions, including liquids, bulk goods or
gases within the fine chemicals, pharmaceutical, water technology and food
The valve’s versatility comes from a broad choice of valve functions and
an extended temperature range of -20¡C to +60¡C.
The new pilot valve can be easily adapted for use with a single-acting
or double-acting actuator for even greater flexibility. For instance, a 5/2-way
valve can be converted into a 3/2-way valve by simply turning the seal round
180 degrees. In the 3/2-way valve, exhaust air is fed via the seal into the
spring chamber of the actuator to protect the spring chamber from contaminated
ambient air and guarantee a longer service life for the pneumatic actuator.
Festo’s ATEX accessories and IEC Ex-certified solenoid systems for zones
1 and 2 and systems certified in accordance with NEC 500 for Class 1 Div. 1 and
Div. 2 are specially made for environments with potentially explosive
Key features of Festo’s standard NAMUR valve VSNC include rotatable seal
for 3/2- or 5/2-way function; wide choice of EX solenoid systems; robust and
capable of high flow rates; suitable for a broad range of applications; extended
temperature range; and excellent price/performance ratio.
