Techcon 5620TFE PTFE Diaphragm Disc Kit

Description

5620TFE diaphragm kit is a Techcon replacement PTFE diaphragm disc kit for diaphragm valve service. Distributor listings identify the kit as part 5620TFE-DKIT, made from PTFE, gray in color, silicone free, and rated for dispensing work up to 100 psi. It supports maintenance on Techcon diaphragm valve systems used with low to medium viscosity fluids.

5620TFE diaphragm kit Service Role

Diaphragm valves isolate the actuation side of the valve from the wetted fluid path. When the diaphragm wears, swells, or becomes contaminated, shot size and shutoff can drift. Replacing the diaphragm parts during planned service helps restore clean cutoff and keeps process fluid away from the air side of the valve.

5620TFE diaphragm kit Applications

• Repair stock for Techcon diaphragm valve maintenance.
• PTFE wetted material for many low to medium viscosity fluids.
• Useful around cyanoacrylates, UV cure materials, anaerobics, solvents, primers, activators, and inks when approved by the process owner.
• Supports valve rebuild work where repeatable deposits matter.
• Compact kit for maintenance benches and production spare bins.

Maintenance Notes

Shut off air and fluid pressure before disassembly, then follow the valve guide for part order and torque. Inspect the fluid housing, seals, and tip adapter at the same time so a fresh diaphragm is not installed against damaged parts. After rebuild, purge the valve and confirm shot size on scrap before returning the station to production.

Keep one spare kit near each high-use valve family so a small worn part does not stop the line. Record the valve model and fluid type when parts are changed, since aggressive fluids and frequent cycling can shorten service intervals.
