12. Internal sensing for North American models
All models except North American models are factory prepared for internal
sensing. When internal pressure sensing is required for North American models,
please contact the nearest TLV representative to request both a connector, which
must be installed in place of the blind pin, and a threaded secondary pressure
sensing plug.* Follow the connector installation procedure shown below:
1) Loosen and remove the four (4) bolts that attach the pilot body to the main
body (15 – 50 mm (
1
/
2
– 2 in)) or the pilot cover (65 – 150 mm (2
1
/
2
– 6 in)),
and remove the pilot valve body.
2) Install the connector by first removing the blind pin from the secondary side of
the main body or pilot cover and then substituting the connector.

3) Re-install the pilot body and fasten the four (4) bolts evenly.
Consult page 30 in this manual for torque requirements of these bolts.
4) If a secondary pressure sensing pipe has previously been installed, remove it
and be certain to install the threaded secondary pressure sensing line plug in
its place.
*Internal sensing should not be used when 15 mm (
1
/
2
in) and 20 mm (
3
/
4
in) MC-
COS-16 will be used below 0.3 MPaG (45 psig) and 0.1 MPaG (15 psig)
respectively, and below 50% of primary pressure.
