Theory of Operation
The PC100 is a high pressure, front closing stainless steel plural component
dispensing valve that can be used to dispense two-part fluids. Applications include
potting, bead placement, and gaskets where a low flow rate is required. This valve works
most favorably with lower viscosity unfilled fluids. Part A and part B fluids will flow into
the valve separately and out of the valve separately into a disposable static mixer. No
disassembly and cleaning of the valve is required at the end of the day.
The PC100 has a divorced design comprising of two major sections. These include:
1) Two air sections (red anodized portions)
2) Fluid section (stainless steel portion)
The separate air sections are aluminum bodies with a simple piston/cylinder
combination used to open and close the valve. Stroke adjustment bolts in the upper air
bodies controls how far the piston and needle assembly can retract.
The fluid section is a stainless steel body, which includes a needle and seat
combination on each side of the valve to control fluid flow of part A and part B. Fluid
dispenses as the needles retracts out of the seats, then stops as the needles moves back
into the seats. The stroke adjustment bolts regulate the distance that the needles can
retract out of the seats thus controlling the rate of fluid flow. Fluids can include but are
not limited to any lower viscosity unfilled epoxies, urethanes, silicones, etc.
Wetted parts on the PC100 include:
- 303, 304 stainless steel
- Teflon
- Kalrez
