CHECK VALVE O-RINGS
Small particles of rust, sand, or grit may build up around the check valve seals. Over time, this may cause a
noticeable decrease in the accuracy of injected product application rates. Clean or replace the o-ring seals
periodically to ensure accuracy of the injection system.
1. Empty and rinse product from the chemical supply tank and flush the injection pump with water.
2. Carefully remove the intake and discharge valve cartridges from the injection pump using a 9/16” Allen wrench.
NOTE: The intake and discharge valve assemblies contain parts which are not interchangeable. To ensure
proper re-assembly, it is recommended that the intake and discharge valve assemblies are cleaned
and inspected separately.
3. Examine the valve assembly o-ring and replace if cut or nicked. These o-rings are made of a chemical resistant
compound and should only be replaced with o-rings supplied by a local Raven dealer.
4. Disassemble the check valve assemblies as shown in Figure 1 below.
NOTE: Valve assembly contains tension springs and small parts. To prevent the loss of parts, place the valve
assembly inside a clear plastic bag while disassembling.
5. Examine the guide, spring, poppet and poppet o-ring for wear, pitting, swelling or foreign matter. Clean or
replace if necessary. O-rings inside valve assembly are made of a chemical resistant compound and should only
be replaced with o-rings supplied by a local Raven dealer.
6. Reassemble the intake and discharge plugs as shown in Figure 1 on page 61.
7. Apply petroleum jelly to valve body o-rings and replace valve assemblies into the pump head and tighten valve
plug.
CAUTION
Valve assembly contains small parts and springs
under compression. Wear safety glasses when
maintaining or cleaning valve assemblies.
Chemical residue and build up may be present
on internal pump components. Wear gloves
when servicing internal pump assemblies.
