An instrument needle valve uses a tapered pin to gradually open a space for fine control of flow. The flow can be controlled and regulated with the use of a spindle. A needle valve has a relatively small orifice with a long tapered seat and a needle shaped plunger on the end of a screw which exactly fits the seat.
Apr 02 2013 A needle valve is a type of valve having a small orifice and a threaded needle like plunger. It allows precise regulation of flow although it is
Needle valve without multi dial. Various needle lineup Features ‘’FFNV1’’ series Smooth and precise flow rate control is possible about 13 rotations by making the needle part non rotating structure. Needle valve can be set according to usage conditions from a wide range of needle valve lineup. We have various seal materials.
To ensure consistent and repeatable settings these valves have color coded handle threads and numerical markings. One full revolution of the handle reveals a new color to indicate the set point. Use these valves with water oil air and inert gas. Turn the handle to adjust flow in small increments for metering sampling and other applications requiring fine flow control.

Needle valves offer the most accurate flow control making them an excellent choice for precise metering of liquids or gases. Needle valves have a tapered needle like plunger that snuggly sits in the valve seat creating a leaktight seal that can withstand high pressures. Operators can fine tune or shut off flow by simply the threaded needle.
A needle valve is a manual valve that used where continuous throttling of flow is required for regulation. Needle valves are similar to the globe valve in design with the biggest difference is the sharp needle like disk. Needle valves are designed to give very accurate control of flow in small diameter piping systems.
Needle valves can withstand greater pressure and have good sealing performance than other types of valves so they are generally used for the sealing of gas or liquid media with small flow and high pressure. Instrument needle valve is an important part of instrument measurement pipeline system. It mainly includes stop valve and ball valve.
