Needle Valves

Instrumentation Needle Valve

The Sophisticated and costly instrument utilized in complex plants need to be installed in step with certain carefully laid down safeguards using selected and reliable accessories. Most of the instrument valves created without any adherence to the rigid codes of the instrumentation industry are unsafe to high pressure use. These needle valves are developed when extensive research to deliver defect free range of special purpose severe service valves. Further, the stem threads rolled and hard plated and tip satellited prevent galling and extends the working life.

1) These needle valves cheaply produced have common deficiencies.

2) Their seal just an 'O' ring Spindle cannot take wear.

3) Leakage due to galling at the tip Spindle Which rotates on closure is prone to galling Normally threads are in contact with process media.

AKI Needle Valve is specially designed to eliminate all the above deficiencies and created beneath the rigid qually control from the basic raw material stage. Needle valves are precises machining on modern machinery to provide top quality and low price, to fulfill the exacting standards of our valuable customers. The offered needle valves range is extensively used for controlling, measuring, equalizing and debilitating the pressure of fluids. Our valuable patrons can avail these products as per their specifications and preference.
