CHAPTER 10 : CHANGING VALVE / ELECTRONICS ORIENTATION
Introduction
From the factory, each SV2 Series valve must be ordered as either right-hand or left-hand valve/electronics orientation as
viewed from the gas outlet end. Refer to digit #10 from
is mounted per the order specification along with side-specific chassis ground wiring, solenoid 1/2 wiring, valve seat 1/2 Open/
Closed LED association and proof of closure 1/2 wiring.
The SV2 Series valve electronics and modules are side flexible, regardless of what orientation was ordered from the factory. As
explained in the Valve Body
molded into the casting including a gas flow directional arrow, valve seat 1 and 2 markings, pressure port access markings (A, B,
C, D) and guide posts for mounting the Pressure Module and C6097 pressure switches to the pressure access ports. Also, each
body has a valve chassis ground connection as well as tapped and threaded holes to affix the electrical enclosure in place. Each
body ordered with NPT port threads has an appropriately sized NOVV (normally open vent valve) connection.
If the valve mounting in the field is such that the electronics and any associated modules must be re-oriented to the other side
of the valve to ensure access to the electronics, follow the procedure outlined below.
NOTICE
DO NOT attempt to change the valve electronics side orientation without following these instructions.
IMPORTANT
• Ensure that the SOLENOID 1, SOLENOID 2, POC 1 and POC 2 internal wiring is properly connected per this procedure.
Failure to do so may cause unnecessary fault conditions.
• If the electronics orientation is changed in the field, the LED ORIENTATION CHANGE PROCEDURE MUST ALSO BE
COMPLETED to ensure the LED annunciation continues to indicate status of the valve seat over which it is situated.
