A new generation needle and shut-off valve provides screwdriver-adjustable control and positive shut-off without damage to the needle. It is ideal for providing hydrogen and air to an FID, since the flow setting is not changed by turning the valve on and off. It can also be used to supply make-up or combustion gas in a wide variety of applications.
The valve body materials are anodized aluminum or stainless steel, with Viton O-ring seals. Maximum temperature is 100°C, and maximum inlet pressure is 100 psig. All are supplied with Valco 1/16" ZDV fittings.
The standard knob is silver-colored and .62" long. Colored knobs for gas identification are available separately, in two lengths.
