Product Manual:  CVS Type 1301F and 1301G Regulator 

 

Assembly 

These are complete instructions assuming the 

regulator was fully disassembled.  If the regulator 

was only partially disassembled, start at the 

appropriate step.  Refer to Figure 2 for key numbers. 

1.

 

Screw the orifice (Key 18) into the regulator 

then insert both halves of the yoke (Key 17). 

Fasten the yoke together with the cap screws 

(Key 15). 

2.

 

The valve disk assembly (Key 19) has two 

disks (one on each end).  Inspect both disks 

and select which one will be used. Thread the 

assembly into the yoke so that the disk to be 

used is against the orifice.  Thread the valve 

disk collar (Key 10) on to the exposed end of 

the valve disk assembly. 

3.

 

Place the bottom cap gasket (Key 8) onto the 

bottom cap (Key 9), then insert the spring 

(Key 3) into the bottom cap and thread the 

assembly into the regulator. 

4.

 

Place the body gasket (Key 16) on the 

regulator body (Key 6). 

5.

 

Refer to Figure 3 and place the diaphragm 

plate gasket (Key 7), the two diaphragms (Key 

14) and the diaphragm plate (Key 13) onto 

the yoke (Key 17).  Ensure the diaphragm 

convolutions are toward the spring and thread 

the diaphragm locknut (Key 4) onto the yoke. 

6.

 

Place the regulator spring (Key 2) and upper 

spring seat (Key 12) onto the diaphragm 

plate. 

7.

 

Position the spring case (Key 2) over the 

spring and on the regulator body. Line up the 

spring case vent or vents, insert the cap 

screws (Key 5) and tighten them by hand. 

8.

 

Thread the adjusting screw (Key 1) and 

locknut (Key 11) into the spring case so the 

spring is just slightly compressed.  Securely 

tighten the cap screws (Key 5) and refer to the 

“Start Up” instructions for proper adjustment 

procedures.
