Metering Valves HR Series
DESCRIPTION
Parker HR Series Metering Valves provide the highest degree of precision metering for moderate pressure applications. A choice of seven precision ground, tapered flat, non-rotating and non-rising valve stems enable repeatable metering at flow capacities as low as 0.0004 Cv
. With 15 stem turns, this valve offers the ultimate in precision flow control. This series also features shut-off capability not found in most metering valves.
FEATURES • Bubble tight shut-off
• Special fine pitch thread with 15 turn resolution is isolated from contact with process fluids • Non-rotating/non-rising valve stem design provides smooth, non-reversing flow characteristics • Seven optional valve stem tapers • Special orifice liner assures long life • Panel or in-line mounting • Angle or in-line patterns
• Brass or 316 SS forged body construction • 100% function tested for actuation and shut-off • 3 handle options • 5 different seat materials available • High temperature and cleaned for oyxgen service options
