REBUILT SST2 BAYONET CONTROL VALVE
These control valves are for use with the Delaval SST takeoffs. They control the vacuum to the cylinder and the sensor for cluster removal.
So which do I need, well It depends on how your system is installed as there are 2 ways to install these SST2 takeoffs.
Most common installation.
If you have a VAC/ATM label on your valve you have a system where each takeoff has its own valve so each valve will connect like this:
The VAC (left side) of the valve connects to the Cylinder
The ATM (right side) of the valve connects to the Sensor
Less common installation.
If you have both VAC/VAC and ATM/ATM labels on your valves you have a system where 2 detachers will share one of each valve so the valves will be ran like this:
The VAC/VAC valve will connect to 2 Cylinders, left side to one cylinder and right side to one cylinder.
The ATM/ATM valve will connect to 2 Sensors, left side to one sensor and right side to one sensor.
Note: When new your valves would have originally came with a label on the front which would read either,
VAC/ATM or VAC/VAC or ATM/ATM
