Maximum working pressure: 60,000psi (4,137bar);Precision throttle is suitable for more accurate control of small flow applications;The special Angle-designed valve needle acts on the accurately matched replaceable valve seat to form a throttle, with a wide flow adjustment range, and a smooth differential pressure change;These valves are only used for measurement, can not be absolutely closed, the minimum flow rate is the factory set, function at the "0", do not operate the valve below the zero position, otherwise it will cause damage;When closure is required, Siteke series valves shall be installed in series with precision metering valves.
