Reassembly of the SuperFlow® 350 Demand Regulator

 

SuperFlow® 350 Regulator

B

 

CAUTION

Be sure the washer and spacer in-

stalled on the inlet valve shaft are in-

stalled in the correct sequence. If they 

are not, the regulator will not perform 

properly.

5) Using the socket wrench from the tool kit, run 

the lock nut onto the inlet valve stem approxi-

mately 1 ½ to 2 turns, leaving enough slack to al-

low installation of the lever. With the inlet valve 

pressed in, the washer and spacer must be loose 

on the inlet valve stem so the lever can be in-

stalled.

6) Check the roller lever. The lever legs MUST 

be parallel to each other and free of any nicks or 

burrs. Check them with a straight edge and align 

them if necessary by carefully bending them with 

pliers.

7) With the inlet valve stem depressed into the 

regulator body, insert the feet of the roller lever 

between the washer and spacer, then release the 

pressure on the inlet valve.

8) Hold the inlet valve with the castle wrench so 

that it cannot rotate, tighten the nut until three 

threads are visible past the nut. This will be ac-

ceptable for initial set up.

9) While holding the lever down, install the 

inlet nipple with its O-ring on, into the regu-

lator body. Using the torque wrench, tight-

en the inlet nipple see "Torque Specs" on 

page APNDX-19 for correct torque. Make sure  

the jam nut is completely threaded on to the inlet 

nipple.

10) Lightly lubricate the piston and spacer. In-

stall the piston, spring set and spacer into the 

adjustment tube of the regulator body, sequence 

as shown in the blow-apart drawing. 

11) For the adjustment shaft, lightly lubricate 

the new O-ring then install it and the new wash-

er onto the shaft.

12) Slide the packing nut onto the adjustment 

shaft, then slip the knob onto the end of the shaft. 

Hold the shaft and rotate the knob until the pin-

holes line up. Use the inlet valve holder - the “L” 

shaped tool (or a 

3/32

” punch), from the regulator 

tool kit to accurately align these holes.

13) Install the retaining pin by tapping it in with 

a small hammer until it is flush with the outer 

surface of the knob.

Install the retaining pin into the adjustment knob.

14) Lightly lubricate the end of the shaft and the 

threads with the appropriate lubricant. Thread 

the adjustment shaft clockwise, using the ad-

justment knob, into the regulator tube until the 

packing nut can be started. 

Back out the adjustment knob once the packing 

nut is engaged on the demand regulator body to 

access the packing nut with the torque wrench. 

Using a torque wrench, tighten the packing nut  

 see "Torque Specs" on page APNDX-19 for correct 

torque.

15) Rotate the adjustment knob in i.e., clock-

wise, several turns, then recheck the torque one 

more time. Ensure the adjustment shaft rotates 

smoothly and there is no binding.

For Quad-Valve Exhaust

16) Stretch the Quad-Valve main exhaust body 

onto the exhaust flange of the regulator. Install a 

tie wrap and tighten. Cut and discard protruding 

end of tie wrap. Rotate as needed so the port and 

starboard whiskers can be installed. 

For Tri-Valve Exhaust

17) Stretch the Tri-Valve

®

 main exhaust body 

onto the exhaust flange of the regulator. Rotate
