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.
