V200E Fail Freeze Positioner

The V200 FF incorporates a unique “fail in place” Ip module that very simply adapts to the base V200P positioner.

Most standard electropneumatic positioners when power (signal) is lost, go to zero, and the pneumatic output will default to one of the positioner ports (on the V200 it is the C- port)-this will drive the valve/actuator in one direction.

The V200FF fail freeze, on loss of power, actually “locks” the air in place due to the unique design of the Ip module.

This means the valve/actuator package will “fail in place”, and will not move, by design, until power is restored and a new input signal is changed. Under normal conditions, the V200FF operates much like other electropneumatic positioners.

Common applications for this product are dampers but can be utilized in critical applications where fail-safe systems are desired.

The Ip module and accompanying plate becomes an integral part of the V200 based product with internal air supplied through the positioner into the special “fail freeze” Ip.

Features

All In One Housing
- This compact NEMA 4X valve positioner allows for an internal I/P, switches, 4/20 mA transmitter, all in one compact, rugged die-cast aluminum housing. The flexibility to add, remove, replace, and calibrate this unit is very user-friendly.
Calibration
- The ability to calibrate a positioner is important. Time can be money, and with the V200 positioner, calibration is made simple, easy, and NOT time-consuming. Both Zero and Span can be adjusted without removing the cover, and the single spring has very little interaction.
Complete Offering
- Being able to get all of the needed options from a single product can be a real benefit. For basic pneumatic to various Ip options (standard, IS, EX, FF, Gas approved, 0-10V) and adding valve position feedback into the one compact housing is a benefit. The flexibility of going from one type to the other in minutes saves time and money. Quality construction of each product equals accurate control and long service life.
Position Feedback
- As the need for valve position feedback grows, the V200 positioner allows for very accurate feedback options. From switches to 4/20 transmitter, these components fit very neatly and simply into the one NEMA 4X housing.
Accessories/Options
- The flexible mounting allows for mounting to many actuators, built in gauge block, various pilot assemblies, special cams, beacon indicator, and more are available from one source-one product.
