Introduction

• The 116950 e-ChemSaver® ES Valve is a solenoid-actuated shutoff compatible with a wide range of TeeJet® nozzle bodies equipped with a diaphragm check valve. It can be used for end-of-boom nozzles as well as individual tip shutoff control.
• The valve is normally closed and opens when the solenoid is energized. The 116950 has a 2-Pin Superseal 1.5 connector molded into the body for a clean, weather-tight electrical connection.
• Application Note(s): Rinse the system with clean water after each application. 80 mesh strainer screen or finer is recommended with all e-ChemSaver® ES Valve applications.

General Disassembly and Reassembly

1. Unscrew the valve assembly from the nozzle body by rotating the interface cap/locking ring (Item counterclockwise until the assembly separates.

2. Remove the FKM gasket (1).

3. Loosen and remove the nylon interface cap/locking ring (2) from the coil assembly (3-7) by compressing the interface cap/locking ring against the coil assembly and turning counterclockwise until separated.

   • All repairable parts should be accessible at this point. The installation spring (3), plunger sub-assembly (4), stainless steel spring (5), and o-ring (6) can be replaced without further disassembly.

4. During reassembly, please ensure that the o-ring (6) is pressed down to the outside base of the threads on the coil assembly(7/7A) to avoid damaging the o-ring when reassembling.

   • Then, place the stainless steel spring (5), and plunger sub-assembly (4) in the coil assembly (717A).
   • Note: The conical-shaped stainless steel spring (5) should be oriented with the wider end resting in the groove of the coil assembly (7/7A) and the narrower end facing outward (visible).
   • Then, place the plunger sub-assembly (4) with the black insert facing outward (visible) and insert it into the narrower end of the spring (5) when placed in the coil assembly (717A).
   • Then place the installation spring (3) onto the base of the coil assembly so that the three tabs lay flat on the base of the coil assembly.

5. Tighten the nylon interface cap/locking ring (2) from the coil assembly (3-7) by compressing the interface cap/locking ring against the coil assembly and turning clockwise until tight.

   • Then place gasket (1) into interface cap and locking ring sub-assembly.
     Torque Specifications: Tighten interface cap/locking ring (2) & coil assembly (3-7) to 12 in-lbs (1.36 N-m)

6. Recommended : At the time of installation, spray a sufficient quantity of corrosion prevention (CorrosionX® CorrosionX® Heavy Duty, or CorrosionX® Aviation) compound into the connector to wet the terminals before plugging the connector in.
