Quick acting and high cycle valve
Quick acting and high cycle valve
(OP)
A customer of ours has an application requiring quick acting and high cycle valves.
Valves will be 1", product is up to 6000cp viscosity, about 8.2 gal/min, cycling on/off 48 times/min (so quick on/off action is desirable also) for 24/7. This is almost 1 million operations per week. One of the products has calcium carbonate in it so we're also concerned with abrasiveness of the product.
My first thought is a solenoid valve. Any other ideas? My experience is in process, not manufacturing, so I've never run across something like this.

Barring that perhaps multiple valves in parallel to distribute the cycles across several valves.
BTW that's only 1/2million cycles a week.

Magnetic valve is a solenoid valve. The main problem here us the 24/7 the sealing face may not hold for long time.

One very impotant info is missing - the differential pressure across the valve orifice.

The polyurethane is abrasion-resistant, and the valve is very quick-acting. There is not much inside the valve to be abraded. These are the valves that they us on the "dancing waters" fountains because they are so quick-acting.
If you want to be a bit more conventional, you could look at a Worcester ball valve with a hardened ball and Ultra-High Molecular weight polyethylene seats. The UHMWPE seats are very abrasion resistant and the Worcester actuator has been documented in low-load high-cycle applications to go as many as 14 million cycles.

Parallel valves (maybe 2 or 3) would allow cycle distribution, and an easy way to replace valves.
Regardless of how good a valve is, after 14 million cycles, you will need to replace something.
