    Precision Flow-Adjustment Valves with Yor-Lok Fittings

    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.

    Precision Flow-Adjustment Valves with Compression Fittings

    The compression sleeve on these valves bites into tubing as you tighten the nut, forming a strong seal. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. All have metal-to-metal seats that resist temperature fluctuations.

    Precision Flow-Adjustment Valves with Yor-Lok Fittings for Chemicals

    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.
