3.0 MAINTENANCE:
Refer to Figure 1, page 3 for part descriptions and locations.
3.1 Repairing Valve
3.1.1 Depressurize and drain system.
3.1.2 Remove the assembly nut and end connector from the end opposite of the flow arrow (see Figure 1) on the body, or the complete
valve body from the piping system.
3.1.2.1 The front face of the seal retainer indicates which direction of rotation tightens or loosens the seal retainer, with the word
“tighten” and a directional arrow, and the word “loosen” and a directional arrow.
3.1.3 Rotate the seal retainer completely in the “loosen” direction and remove it from the valve body.
3.1.3.1 Seal, o-rings, and ball can be removed.
3.1.4 O-ring replacement
3.1.4.1.1 Carefully remove the o-rings from their respective locations taking care not to scratch their sealing surfaces.
3.1.4.1.2 Use a non-petroleum base lubricant to lubricate the o-rings, and re-assemble the valve.
3.1.5 Using a plastic pick, carefully remove the old seals. NOTE: Be very careful not to damage the o-ring grooves or valve body.
3.1.6 Clean o-ring grooves with a soft brush or cloth.
3.1.7 Install new o-rings by gently pressing o-ring into groove until o-ring is fully seated.
3.1.8 Install valve cartridge between end connectors, match nuts to body threads and turn nut clockwise to thread onto body. Using a
strap wrench only (never use a pipe wrench), nut can be tightened ¼ - ½ turn past hand-tight, as needed.
3.1.8.1 Never install valve into system where assembly nuts have to be used to pull system together. This will apply undue loading
on the valve body and assembly nuts. Piping system should be properly aligned prior to valve installation.
3.1.8.2 Never install valve into system that must be forcibly separated in order to allow space for body. This will apply undue
loading on the valve body
WARNING
System must be depressurized and drained prior to installing valve or performing maintenance. Failure to depressurize and
drain system prior to installing or maintaining valve may result in product damage, property damage, personal injury, or even
death.
