Needle Valve S S

Sealmech range of Needle valves are available in bar stock
round & Square body with Screwed (BSP/NPT), Socket Weld, Butt Weld
& Flange End Connection. Needle valves are similar in design and
operation to the globe valve. Instead of a disk, a needle valve has a
long tapered point at the end of the valve stem. The long taper of the
valve element permits a much smaller seating surface area than that of
the globe valve; therefore, the needle valve is more suitable as a
throttle valve.
Normally the material of Needle Valve bodies and its
various parts is SS 304, SS316, SS 304L or SS 316L, but depending on the
application and the system requirements brass, monel, hastalloy can
also be used.
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.
Sealmech Needle Valve Size range is from 1/4" to 2" in round and square body construction and pressure rating up to 5000 psig.
