About Actuated On/Off Valves

About Flowmeters and Totalizers

Flowmeters measure the rate of flow for a liquid or a gas. Totalizers measure the cumulative flow volume. Flowmeter/totalizers display both the flow rate and the cumulative flow volume.

Plastic Noncontact Flow-Adjustment Valves

With no metal parts, these valves are often used for noncontact flow adjustment in wet conditions and harsh environments. All press down on the outside of tubing to adjust flow without contacting the process media. They can be used with any media that’s chemically compatible with your tubing.

Valves with a closed body securely hold tubing in place.

Valves with an open body provide easy access to tubing for maintenance or replacement.

Dial handles are marked with a 1 to 10 mm scale that allows you to make repeatable adjustments.

Tabs have flow-adjustment notches that allow you to lock in adjustments.

Noncontact Flow-Adjustment Valves

Valve Type: Pinch
For Use With: Water, Oil, Air, Deionized Water, Diesel Fuel, Ethylene Glycol, Fuel Oil, Isopropyl Alcohol, Kerosene, Methanol, Mineral Spirits, Sodium Hydroxide, Sodium Hypochlorite

Also known as pinch valves, these press down on the outside of tubing to adjust flow without contacting the process media. They can be used with any media that’s chemically compatible with your tubing.

Nickel-plated brass valves are more corrosion resistant than zinc or zinc-plated steel valves.

Valves with an open body provide easy access to tubing for maintenance or replacement.

Valves with a closed body securely hold tubing in place.

Panel-Mount Noncontact Flow-Adjustment Valves

Valve Type: Pinch

For installation in instrument panels, these valves have a hex nut and threads below the handle. They press down on the outside of tubing to adjust flow without contacting the process media. Valves can be used with any media that’s chemically compatible with your tubing.

Tap Valves

Valve Type: Saddle
For Use With: Air, Water
For Tube Material: Copper

Also known as saddle valves, these self-piercing valves tap existing copper tubing lines so you can install a secondary water supply line to humidifiers, ice makers, and other equipment. Clamp the valve into position and turn the handle to pierce a 1/4" hole in the tubing. Do not use with pipe. The outlet connection is a 1/4" compression tube fitting.

Specifications Met: CE Marked

For applications sensitive to contamination, these valves stop flow without contacting the process media by pressing down on the outside of tubing. They operate on electricity to automatically start and stop flow.

These valves are normally closed unless actuated. They don’t require a minimum pressure drop between the inlet and outlet for operation. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

Pipe-Mount Flowmeters for Water

Install these flowmeters without disassembling your pipeline. Drill a hole in an existing run of PVC pipe and secure the flowmeter with the included clamps. They measure the flow rate of water in your system. For use with Schedule 40/Schedule 80 PVC pipe, they have a dual scale that shows flow rate in gallons per minute for each schedule.
