Threaded Precision Flow-Adjustment Valves for Chemicals
To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a fluoroelastomer seal and a plastic body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

- Valve Type: Needle
- For Use With: Water, Citric Acid, Diesel Fuel, Ethylene Glycol, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Nitric Acid, Phosphoric Acid, Salt Water, Soap Solutions
- Seal Material: Fluoroelastomer Rubber
- Seat Material: PTFE Plastic
- Needle Material: PVC Plastic
Precision Flow-Adjustment Valves with
Push-to-Connect Fittings for Food and Beverage
- Valve Type: Needle
- For Use With: Food, Beverage
- Seal Material: Buna-N Rubber
Insert tubing into the fittings on these valves—no heat, solder, or flux required. Designed for use in food and beverage tubing lines, they adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Threads and a hex nut below the handle allow you to install these valves in instrument panels. They have a nut that can be tightened to compress the packing if it leaks.

Precision Flow-Adjustment Valves with Barbed Fittings for Food and Beverage
- Valve Type: Needle
- For Use With: Food, Beverage
- Seal Material: PTFE Plastic
These valves have barbed fittings that grip onto tubing, providing a secure hold. They’re often used in food and beverage tubing lines to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Threads and a hex nut below the handle allow you to install these valves in instrument panels. They have a nut that can be tightened to compress the packing if it leaks.
