Precision Flow-Adjustment Valves with Yor-Lok Fittings
- Valve Type: Needle
- For Use With: Water, Oil, Air, Argon, Helium, Krypton, Neon, Xenon
For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Valve body is 316 stainless steel for excellent corrosion resistance. Valves have metal-to-metal seats that resist temperature fluctuations. All have a nut that can be tightened to compress the packing if it leaks.
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.

Precision Flow-Adjustment Valves with Yor-Lok Fittings for Steam
- Valve Type: Needle
- For Use With: Steam
- Seal Material: PTFE Plastic
For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. These valves are often used in petroleum refineries. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Body is 316 stainless steel for excellent corrosion resistance. For installation in instrument panels, valves have threads and a hex nut below the handle. They have metal-to-metal seats that resist temperature fluctuations. All have a nut that can be tightened to compress the packing if it leaks.
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.

Precision Flow-Adjustment Valves with Yor-Lok Fittings for Chemicals
- Valve Type: Needle
- For Use With: Oil, Acetone, Air, Ammonia, Argon, Butane, Carbon Dioxide, Deionized Water, Diesel Fuel, Ethanol, Gasoline, Helium, Isopropyl Alcohol, Kerosene, Krypton, Methanol, Methyl Ethyl Ketone, Mineral Spirits, Natural Gas, Neon, Nitrogen, Oxygen, Propane, Soap Solutions, Sodium Hydroxide, Toluene, Xenon, Xylene
- Seal Material: PTFE Plastic
- Seat Material: 316 Stainless Steel
- Packing Material: PTFE Plastic
- Needle Material: 316 Stainless Steel
For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. The 316 stainless steel body, seal and needle, and the PTFE seat and packing can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle 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 mount these valves in instrument panels. All have a nut that can be tightened to compress the packing if it leaks. Valves have bubble-tight soft seats that provide a tight seal when the valve is completely closed.
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.
