Valve Position Indicator
VPX Series
DESCRIPTION
Valve Position Indicator, VPX Series switches are built
especially for outdoor use in potentially hazardous
atmospheres. The switch enclosures are constructed to
withstand the pressure of an internal explosion. Flame paths
cool the exploded gases to a point less than the lowest safe
operating temperature of the surrounding gas. The VPX Series
versions equipped with the inductive proximity switches
has the Intrinsically Safe (IS) rating. Regardless of where the
equipment or machinery is designed, built or installed, the VPX
Series products carry global agency coverage.
The VPX Series switches have standard rugged die-cast
aluminum housing. The products housing is weather sealed
for outdoor use and comply with NEMA 4X requirement for
protection against corrosion, in addition to various NEMA
enclosure standards.
The product’s o-ring seals make the enclosure rain tight,
but are outside of required flame paths so explosion proof
requirements are maintained. The VPX Series switches
are available in multiple colors and angles, visible from all
directions. Unless special ordered, all basic switches operate
on clockwise and counterclockwise rotation.
DIFFERENTIATION
• With numerous environmental ratings (Ingress Protection
and NEMA), the VPX Series is protected for all kinds of
outdoor conditions
• VPX Series is certified flame-proof, explosion-proof and
Intrinsically Safe (optional), thereby making the product safe
for a wide variety of potentially hazardous area applications
• The Safety Integrity Level, SIL 3 certification, puts the VPX
Series in the higher safety category as compared to its
competitors
FEATURES
• VPX Series switches are certified for ATEX, IEC Ex, CE, cULus,
NEPSI, and KOSHA specifications for global applications
that requires protection from explosive gases, vapors &
combustible dust
• Die-cast aluminum housing and various sealing (NEMA 4,
4X, 6, and 13), certifies the VPX Series is rated for rain, wind,
snow, ice and blowing dust environments
• Wide operating temperature range from 40 °C to 80 °C (see
Table 1 for detailed specifications)
• Versions of the VPX with proximity switches carry an
Intrinsically Safe (IS) rating
• Well suited for up to 500,000 actuation cycles
• Available in multiple indicator colors that is visible from all
directions
VALUE TO CUSTOMERS
• cULus, ATEX, IEC EX, NEPSI, and KOSHA certified for
hazardous (explosive) environments
• Designed with the end user in mind, these switches help
to create user-friendly interfaces with broad applications
possibilities to help meet the challenges of many different
environments
• Weather sealed to NEMA and IP ratings
• Reliable, dependable and accurate
• Versions available in both snap-action switches and
intrinsically safe inductive proximity switches
