Uneven cooling is the quiet enemy in molds, dies, casting, and forging work. One circuit runs warmer than the next, parts warp, cycle times stretch, and you're left guessing which line is the problem. A flow regulator is supposed to make that visible, but the real question is whether a compact regulator can give you the per-circuit visibility you need without turning the bench into a plumber's puzzle. The IMS Industrial Molding Supplies Water Flow Regulator 2 Zone #105398, listed at USD 169.00, is a used unit that brings a surprising amount of per-circuit detail to the bench.
Quick verdict
If you're tired of guessing which mold circuit is running hot or slow, this IMS regulator is worth close attention. It has a practical layout and should earn its place on the bench.
Who it suits
This regulator fits molding setups that run within its pressure and temperature limits and need a direct way to watch two circuits. It's also handy for troubleshooting, because you can isolate a circuit and watch the effect on flow.
What stands out from the listed details
The calibrated sight tubes carry set-point markers on each tube, so you can spot a drifting circuit quickly. Solid brass floats and shutoff valves at each station are part of the design, and the feed and return fittings are arranged for a tidy hookup: straight barbs on the bottom for the feed, 90-degree barbs on the back for the return from the mold. The 1-inch NPT brass inlet and outlet provide a standard supply connection.
Meaningful trade-offs
The maximum working pressure is 100 psi and the maximum temperature is 170°F, which rules out hot-runner or high-pressure loops. The feed and return lines are 1/2-inch barb fittings, so verify that matches your tubing. It also covers only two zones, so larger multi-circuit molds will need more than one unit.
Bottom line
For a shop that wants per-circuit flow and temperature visibility without a big footprint, the IMS #105398 gets the job done. The listed price of USD 169.00 reflects the level of control on offer, and the brass components are a plus. Respect the pressure and temperature ceilings, and this regulator will fit right in.
IMS Industrial Molding Supplies Water Flow Regulator 2 Zone # 105398
This used IMS regulator combines calibrated sight tubes with set-point markers, solid brass floats, and per-station shutoff valves. The 1-inch NPT inlet and outlet, plus the barbed feed and return fittings, make the hookup straightforward. It's a two-zone unit with a 100 psi and 170°F operating window, so keep that in mind for your process.
