Barstock Metering Valves MFVTM
Designed for controlling very low flow rates of liquids and gases, MFVTM Barstock valves are available in six conveniently overlapping orifice-needle sizes. Offered in straight (T) and 90 degree (L) flow patterns, the MFVTM Barstock Valve includes a “non-rising stem” design, it’s unique non-rotating needle is cylindrical with a precision ground tapered metering surface. The needle moves in a rectilinear fashion which accounts for its desirable sixteen- turn high resolution attribute. Hysteresis is virtually eliminated due to the needle design and the closely fitting fine thread on its adjustment plunger. The valve body is precision machined chrome plated brass or type 316 stainless steel. |
