Servicing Pilot Valve Assembly

Note: Assure water supply to sprinkler is positively shut off and all residual pressure has been bled. If sprinkler is pressurized, main valve will open when the pilot valve control tube is disconnected.

Refer to Figure 7 for the following procedure.

1.Carefully remove turf and soil from side of sprinkler to expose pilot valve and control tubing.

2.Remove two retaining screws from pilot valve housing.

3.

Pull pilot valve assembly away from sprinkler body and cut control tubing just below tube retainer.

Unless

 

pilot valve has been previously removed, control tubing length will be sufficient for re-connection.

 

4. Remove tube retainer and remaining piece of control tubing from valve body fitting.

 

5. Remove solenoid (1) or NC adapter (2) by turning it counterclockwise.

 

 

6.

Pull pilot valve body assembly (4–12) out of housing.

 

 

7.

Remove diaphragm assembly (12), piston (11) and spring (10).

 

 

8.

Remove selector (7) and plunger assembly (5 or 6).

Selector retains plunger in body.

 

9.

Thoroughly clean and inspect all parts. Replace damaged parts as necessary and reassemble in reverse order.
