Maintenance
Disassembly and Cleaning
1. Remove the manifold and seat plate (8). Pry bar slots are provided.
2. Remove the air cylinder bolts (2) and wiggle the air cylinder apart.
If the assembly is frozen, use the pry bar slots on the valve body
(7) to separate the valve body (7) from the tie plate (5). Insert flat
pieces of metal between the valve body and the tie plate as per
Figure 1. Thread the manifold screws (36) into the back of the tie
plate and push the valve body apart. Apply uniform pressure to
prevent the body from cocking and bending the air cylinder shafts
(75).
3. Once apart, the parts should be cleaned. We recommend
overnight soaking in suitable solvent. All parts can be soaked
except the handle and air cylinder.

Rebuilding the Autovalve
1. After cleaning, inspect the following components:
a. Seat plate (8) on sealing surface
b. Manually retract and extend the shafts (75) from air cylinder (1).
c. If the optional handle is used, connect air into the inlet and check 4-way action of cartridge valve (103).
2. Refer to page10 for a repair kit which contains lip seals, O-rings, and front seals.
3. Lubricate lip seals (3) and shafts (75) with auto grease (read SDS prior to use).
4. Insert four back lip seals (3): two into tie plate (5) and two into the valve body (7). The lip seals are two pieces: an O-ring
and a U-cup. They should always be installed with the O-ring facing the material inlets (body of the valve).
5. Push the air cylinder (1) thru the tie plate (5) and the valve body (7) and engage the screws (2).
6. Push front seal (13) and washer (12) onto adjustment screw (14). To prevent binding, apply auto grease to the threads on
the adjustment screws (14). Thread the seal and adjustment screw assembly into air cylinder shafts.
7. Assemble the seat plate (8) onto the valve body (7).
Final QC Check
Before the manifold is assembled, we recommend air be connected to the air cylinder (1) and the open / close function of the
front seals (13) be inspected for leakage.
The front seals cold flow into the proper shape as the valve is used. It may be necessary to pressurize the air cylinder, but not
the A & B fluids.
