2 X117H Valve Position Transmitter
The Cla-Val Model X117H Valve Position Transmitter is an accurate monitor of the valve position.
Through an industry standard 4-20mA, the X117H delivers accuracy within 100 micrometers. This
position transmitter easily provides the accuracy required for computer-guided control valve systems
(SCADA). The sensor requires a supply voltage of 15-30 VDC. Power can be supplied by either the X35 or
an external power source.
The X117H consists of two main parts: the
X101D Position Indicator and the X117H
Sensor Assembly. The X117H can be retrofit to
almost any Cla-Val valve. The X117H also
includes a newly designed indicator body
which allows for easier bleeding in any
situation. The new body includes a weep hole
above the sight glass (see Figure 2.1 ) that can
be opened via a set screw mounted in the top
of the position indicator. This greatly reduces
the likelihood of misplacing or breaking the
bleed screw while allowing easy removal of air
from the indicator housing.
The position sensor used in this assembly utilizes 3
LED’s to allow the user to monitor device status
visually ( Figure 2.2 ).
