Valve Maintenance for a Viper Nozzle

Taking it apart

• Remove handle hardware screws; parts 15 and 6 on the Diagram
• Pull the bail off the body of the nozzle; part 18
• Remove the tip of the valve (this simply un-screws, a recessed lug spanner might help with VB1560 tip); part not shown on diagram
• Unscrew the seat retainer Assembly; parts 10, 11 and 12
• The ball can now be pulled out; part 4
• The ball actuator can be pulled out by pushing it into the valve body; part 13
• Remove the swivel set pin and twist the swivel until all the ball bearings are out; parts 16, 17
• Pull the swivel out of the valve body; parts 1, 2, 3
• Clean the valve and its parts with ‘non-detergent’ soap and water if necessary

Putting it back together

• Place the new actuator in the hole that the old one came out of with the trunion horizontal (in-line with the valve); part 13
• Place the ball into the valve body with the ball facing up this makes the flat part the front when the ball is closed. If you have the new metal ball either way is fine; part 4
• Holding the ball, place the bail back on the valve body; part 18
• Put thread locker on the ball locator pin and screw it back into the valve body through the bail; part 6 (the bail should now actuate the movement of the ball)
• Replace the seat retainer assembly. Tighten it down till there is no leak around the ball if there is a small leak around the threads the tip will stop that; parts 10,11, and 12
• Grease the swivel O-ring (part 3) and the ball bearing track. Insert the swivel into the valve body; parts 1, 2, and 3
• Insert the ball bearings (there are about 30). Place thread locker on the swivel set screw and insert it into the valve body, so the top of the screw is flush with the valve body
• Replace the tip and tighten it down
• Test the valve before using
