2. UNPACKING AND INSPECTION Carefully unpack the valve and examine the items contained in the carton. These will include:  Valve Assembly  Valve bracket  Sample Needle Kit and fluid line t  User Guide  Valve Air Hose

Inspect the unit for any damaged which may have occurred in transit. If such damage has occurred, notify the carrier at once. Claim for damage must be made by the consignee to the carrier, and should be reported to the manufacturer. 3. DESCRIPTION The TS5620 Series Diaphragm valves are designed to dispense low to medium viscosity fluids. An internal spring return makes the valve fully adaptable for use with any time/pressure controllers. A short opening stroke provides extremely fast, positive shut-off. An external stroke control adjustment makes it easy to fine tune shot sizes. The TS5620 Series compact design allows for mounting flexibility and easy integration into automated applications.

4. THEORY OFOPERATION

The TS5620 Series Diaphragm Valves are normally closed, adjustable stroke valves. Input air pressure of 70-90 psi (4.8 to 6.2 bars) through port (1) drives the piston assembly (2) back, opening the material path, allow fluid flow from the material inlet (3) to the material outlet (4).

Relieving the input air pressure allows the piston return spring to close the diaphragm, ensuring rapid “fail-safe” shut-off of fluid flow.

Figure 3.0

5. SETUP INSTRUCTIONS Refer to figure 4.0

1. Connect the fluid reservoir feed tube (1) to the valve inlet port (2). 2. Connect the valve airline (3) to the valve controller or other pneumatic device that is used to control the valve. 3. Connect appropriate dispensing tip or nozzle to the fluid outlet port (4). 4. Set the valve controller pressure at 70 psi (4.8 bars) 5. Set the fluid reservoir pressure. Do not exceed 70 psi (4.8 bars) 6. Make sure all connections are tight 7. Place container under the valve outlet and activate the valve until the fluid flows steady.

The amount of fluid that flows through the valve is determined by:  Valve open time  Fluid reservoir pressure  Dispensing tip size

7. TROUBLESHOOTING

PROBLEM

POSSIBLE CAUSE

CORRECTION

Fluid pressure too low

Increase fluid pressure

Operating pressure too low

Increase air pressure to 70 psi (4.8 bars)

Dispense tip clogged

Replaced tip

No fluid flow

Fluid cured in valve chamber

Clean valve thoroughly

The stroke adjustment closed

Open stroke adjustment counterclockwise

Fluid pressure fluctuating

Make sure fluid pressure is constant

Valve operating pressure is too low

Increased valve pressure to 70 psi (4.8 bars) Check to make sure the valve controller is providing a consistent output

Inconsistent fluid flow

Valve open time is not consistent

Air trapped in fluid housing

Purge valve

Fluid drools after the valve closes, eventually stopping

Air trapped in fluid housing

Purge valve

Worn diaphragm

Replace diaphragm

Worn fluid housing

Replace fluid housing

Steady drip

Fluid pressure exceeds 70 psi (4.8 bars) Valve re-assembled incorrectly after cleaning

Lower fluid pressure

Refer to Maintenance section

Fluid leaks between diaphragm and fluid housing

Mounting screws loose

Tighten screws

Fluid leaks out of bleed hole Diaphragm ruptured

Replace diaphragm

8. MAINTENANCE ANDCLEANING Normally, purging the valve with appropriate flush material or solvent after use is sufficient for cleaning. However some material may cause a buildup in the valve chamber, in this case periodic and thorough cleaning will be required.

CAUTION: Make sure the fluid pressure is released before disassemble the valve.

8.1 Cleaning

Refer to figure 6.0 1. Release fluid pressure 2. Disconnect fluid line 3. Disconnect valve air line 4. Remove the two socket head cap screws (1) from the fluid housing (2) 5. Pull the fluid housing away from the air cylinder assembly (10) 6. Clean Diaphragm (3) and fluid housing (2)

NOTE: Avoid using sharp probes for cleaning. Any nicks or scratches on the diaphragm or the sealing area of the fluid housing may cause leakage.

7. Reinstall the fluid housing (2). 8. Align the fluid housing mounting holes with diaphragm and air cylinder holes. 9. Reinsert the two socket head cap screws (1). Tighten in accordance with the Torque specifications Chart below.

8.2 To Change the Diaphragm Tool required: Flat tip screwdriver, Snap ring flier, 7/64” hex wrench.

1. Remove the two socket head cap screws (1) from the fluid housing (2) 2. Pull the fluid housing away from the air cylinder assembly (10) 3. Remove the old diaphragm (3) by unscrew it in the counterclockwise direction. 4. Install the new diaphragm by threading it in the clockwise direction. Make sure the internal thread on the diaphragm is not stripped or cross-threaded. 5. Hand tightened the diaphragm until it bottoms against shoulder on piston rod. At this point, do not over tighten or loosen the diaphragm to align the diaphragm and air cylinder holes. 6. The valve is designed so that the fluid housing can be rotated in 45  increments to allow for material input/output alignment. To align the holes of the diaphragm with the appropriate holes in the air cylinder body, insert a small flat tip screwdriver through the hole in the stroke control knob (8) and engage the piston rod slot. Turn the screwdriver clockwise to rotate the rod, piston and diaphragm assembly until the appropriate holes are lined up. 7. Reinstall the fluid housing (2). 8. Align the fluid housing mounting holes with diaphragm and air cylinder holes. 9. Reinsert the two socket head cap screws (1). Tighten in accordance with the Torque specifications Chart below.

8.3 To Change or Lubricate Piston O-ring 1. Remove the fluid housing (2). 2. Remove the diaphragm (3).

3. Remove the stroke control knob (8) and spring (9). 4. Remove the retainer ring (5) and anti-rotating washer (6). 5. Remove the piston assembly (11). 6. Replace O-ring (4) if damaged; otherwise lubricate O-ring with O-ring grease. 7. Reinstall piston, retainer ring and anti-rotating washer.

8. Reinstall spring and stroke control knob. 9. Reinstall diaphragm and fluid housing.
