IDMHDV-130 Handheld Diaphragm Valve User Manual

Theory of Operation

The IDMHDV-130 is an all-plastic handheld dispense valve that uses a unique rigid

diaphragm design to act as a front closing valve to accurately dispense small dots and

fine beads. This valve is designed for handheld applications, to take the place of

traditional syringe dispensing or other manually applied fluids. The all-plastic

construction allows adhesives such as cyanoacrylates and anaerobic materials to be

dispensed through the valve along with a variety of other low to medium viscosity

fluids. Applications can include potting and the dispensing of dots and beads.

The IDMHDV-130 body comprises:

1) Air section (aluminium top portion)

2) Fluid section (acetal body with PTFE diaphragm and polyethylene luer

adapter)

Air Section

The air section is an aluminium body with a simple piston/cylinder combination using

air to open the valve and a spring to close. A stroke adjustment bolt in the upper air

body controls how far the piston and needle assembly can retract, thus regulating the

rate of fluid flow along with a lock nut to hold it in place.

Note: Upon delivery, the stroke adjustment bolt is fully closed.

Fluid Section

The fluid section is made up of acetal with a rigid PTFE diaphragm connected to the

air piston. Fluid dispenses as the point of the diaphragm is lifted out of the fluid section

orifice then stops as it moves back into place. The stroke adjustment bolt of the air

cylinder regulates the distance that the diaphragm tip can lift out of the fluid section

orifice thus controlling rate of fluid flow. An M3 female thread is available in the fluid

section to hold a grounding wire in place to remove any ESD charge.

Wetted parts on the IDMHDV-130 include:

•Acetal (ESD Safe)

•PTFE

•Polyethylene

Safety

Due to material contents being under pressure, eye protection is recommended for

operators. Refer to the SDS for the material being dispensed for other precautions.

6) Remove the cylinder cap (7) and stroke adjustment assembly (8, 9) from the

air cylinder (6) to remove the spring (12).

7) Insert a flat head screwdriver into the slot of the piston (5) to hold it in place

then spin the diaphragm (2) counter-clockwise to unthread it from the piston.

8) Slide the cylinder end cap (4) off the piston.

9) Push the threaded end of the piston (5) into the air cylinder (6) to slide it

through the back and remove.

10) Remove the 007 Nitrile O-ring (15) from the air cylinder and the 116 Nitrile

O-ring (13) from the piston (5).

11) Clean all of the wetted parts thoroughly with an appropriate solvent.

Replace components with spares provided in the spare parts kit, if necessary.

General Assembly

All O-rings must be lubricated with a small amount of silicone grease.

1) Thread the lock nut (9) onto the stroke adjustment (8) with knurled side first.

2) Thread the stroke adjustment (8) into the cylinder cap (7).

3) Mount the 116 Nitrile O-ring (13) onto the piston (5).

4) Apply a small amount of silicone grease to the inside of the air cylinder (6)

then drop in the piston (5).

5) Mount the 007 Nitrile O-ring onto the end of the piston (5) and slide it down

into the groove of the air cylinder (6).

6) Place the cylinder end cap (4) onto the piston (5), lip side first and slide up

to the air cylinder (6)

7) Using a square head screwdriver, hold the piston (5) in place and thread the

diaphragm (2) on tightly.

8) If the diaphragm (2) does not square up with the air cylinder (6) use the

square head screwdriver to turn the piston until it is aligned.

9) Place the 016 FFKM O-ring (14) into the groove of the fluid body (1).

10) Place the air cap & diaphragm assembly on top of the fluid body (1) and

assemble with four machine screws (11) using a 3/32” Allen key to tighten

them down evenly.

11) Thread the plastic luer adapter (4) into the bottom of the fluid section (3)

and tighten using a spanner.

Note: Be sure not to over-tighten the luer adapter (4).

IDMHDV-130 Handheld Diaphragm Valve User Manual

Operation

1) Set up the valve as outlined in the Setup procedures (page 3).

2) Regulate the air pressure operating the valve between 50-80psi.

3) Making sure that the valve is not aimed toward anyone, cycle the valve several

times. When the valve is cycling, the piston (5) can be heard hitting the stroke

adjustment bolt (8). If the valve is not cycling properly, refer to the

Troubleshooting section (page 8).

4) When the fluid delivery system is connected to the valve, pressurise the

material to be dispensed.

5) Once again, cycle the valve open to purge. Fluid should begin to dispense from

the tip of the valve. Elevate the valve with the tip pointing up in the air, then

hold a purge cup underneath the tip and cycle the valve to open until all air is

removed.

6) Check fluid connection for leaks. If the valve is leaking or dripping, refer to the

Troubleshooting section (page 8).

7) Adjust the material pressure until the desired fluid flow is achieved.

8) Turn the stroke adjustment bolt (8) until the desired flow rate is achieved.

Turning the adjustment clockwise will decrease the material flow rate and

counter-clockwise will increase the material flow rate. If the stroke is turned all

the way down, it will stop fluid flow entirely.

9) Once the stroke is set, tighten the lock nut (9) against the cylinder cap.

Note: refer to the Troubleshooting section (page 8) for any problems.

Routine Cleaning and Disassembly

Cleaning and rebuilding the valve will be required from time to time. A spare parts kit

(IDMHDV-130-SP) is available with all the normal wear parts included (1 x Diaphragm

(IDMHDV-130-114-9539), 1 x Nitrile O-Ring (IDMHDV-130-VLV-116B), 1 x FFKM O-Ring

(IDMHDV-130-VLV-016K), 1x Nitrile O-Ring (IDMHDV-130-VLV-007B) and 1 x Plastic

Luer adapter (IDMHDV-130-V300-UV)). Contact Intertronics to order.

1) Flush the valve thoroughly with an appropriate solvent before disassembly.

(Refer to SDS of fluid for suggested solvent).

2) Remove fluid pressure from the system, and then remove all fluid delivery

fittings, hoses, etc. from the valve. Remove operating air pressure from the

valve.

3) Using a spanner, unthread and remove the luer adapter (10) from the fluid body

(1).

4) Using a 3/32” Allen® key, evenly remove the four machine screws (11) from

the cylinder cap (7).

5) Pull the fluid body (1) apart from the upper assembly and remove the 016 FFKM

O-ring (14).

Set Up

To actuate the air section the IDMHDV-130 requires a dispensing controller, such as

the FISDC100 Automatic liquid dispenser. Contact Intertronics for more information.

The valve should be operated with clean, dry air between 50-80psi. One #10-32

threaded air port is located on the air section of the valve to open the valve when air

is applied. A spring is then used to return the valve to the closed position. A quick

connect air fitting is typically supplied with the IDMHDV-130 to fit 5/32” tubing.

Fluid is supplied to the IDMHDV-130 through the 1/8” NPT port located on the acetal

fluid section of the valve.
