Overview
Complete trigger valve assembly for the Sapphire Scientific Clear-View Upholstery Pro (AW59). Sapphire part number 23-070, Sapphire code 120070. Listed in the parts schedule as the trigger and valve body.
This is the PMF V4N valve with trigger.
Rebuild or replace?
Sapphire's user instructions give two repair options for a trigger that leaks or will not release enough solution:
- Option A — rebuild. Stem replacement kit 48-064. Cheaper, and the first thing to try. Trigger lever off, stem retention nut off, new stem in.
- Option B — replace the assembly. This part. A longer job: four cover screws, depress the hose release ring and withdraw the solution outlet tube without kinking it, remove the outlet tube fitting from the valve body, then disconnect the inlet hose assembly.
Go to Option B when the valve body itself is damaged — a stripped thread, a cracked body, or a seat that a new stem will not seal against. If the fault is wear, the stem kit is the right answer.
Before you replace anything
Sapphire instruct you to confirm the glide is not plugged or damaged before concluding the trigger needs service. Also check the inline strainer (20-006) and the orifice plate (20-035) on the flow adjust assembly — both produce "not enough solution" and neither is a valve fault.
Sapphire's own user instructions for the Upholstery Pro (document 07-01713B) are clear that this tool is designed to be serviced in the field with basic hand tools in a few minutes. That is worth taking them up on — an upholstery tool that has gone off is usually a five-minute job, not a new tool.
Fitting advice
Do not kink the solution outlet tube when you withdraw it — Sapphire call this out specifically, and a kinked tube is a second part to buy.
Note the orientation of the valve body and the routing of the inlet hose before you disturb them.
