Needle Valve
Needlevalve has a long tapered point at the end of the valve stem. Needle valve is
more suitable as a throttle valve. Needle valves are used to control flow into delicate
gauges, which might be damaged by sudden surges of fluid under pressure. Needle
valves are also used to control the end of a work cycle, where it is desirable
for motion to be brought slowly to a halt, and at other points where precise
adjustments of flow are necessary and where a small rate of flow is desired.
Many of the needle valves used in fluid power systems are manually operated;
this valve is constructed with a hand-wheel and is adjusted to provide a
specific rate of flow. This rate of flow will provide a desired time of
operation for a particular subsystem. Since this of valve can be adjusted to
conform to the requirements of a particular system, it can be used in a variety
of systems.
Needlevalves are available in forged model or cast model, specifications for needle
