HB Series Needle Valves are heavy-duty instrumentation valves designed for precise flow control and reliable shut-off in high-pressure systems. These valves are commonly used in process control, instrumentation lines, and industrial applications where accurate regulation of liquids or gases is required.
Designed for reliable sealing and precise throttling, HB Series needle valves feature a non-rotating vee-tip or ball-tip stem that ensures smooth operation and repeated leak-tight shut-off. Standard packing materials such as PTFE provide effective sealing, while optional graphite packing can be used for high-temperature applications.
