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.
