Description
Metering Valves
• The design of Barrel and Thimble micrometer permits repeatable settings. Each division of barrel equal to 0.025″
Thimble is divided into 25 divisions, each division of thimble equal is to 0.001″ stem travel
One revolution equal to valve stem 0.025″ travel
• Precise Metering valves are not intended for use as shut-off valves
• The minimum flow rate is factory set at “0” position. The valve will be damaged when the valve is operated below “0” position. When shut-off is required, a correlated shut-off valve from 15B, 20B, 15N, 20N, 30N and 60N series valves should be installed in series with the Precise Metering valves
• Packing is located under the thread of valve stem
• Reliable locking device for packing gland
• Extended stuffing box valve with graphite can be operated to 1200 ̊F (649 ̊C)
