Needle Valves

Additional Details

We are involved in offering a wide range of Needle Valves. This sophisticated instrument is used in complex plants need to be installed according to certain carefully laid down safeguards using selected and reliable accessories. Most of the valves are produced without any adherence to the rigid codes of the instrumentation industry are unsafe to high pressure use.

Cheaply produced valves have common deficiencies:

    Their seal just an O ring spindle cannot take wear
    Leakage due to galling at the tip spindle which rotates on closure is prone to galling
    Normally threads are in contact with process media.

Our range is specially designed to eliminate all the above deficiencies and produced under rigid quality control from basic raw material stage. Valves are precises machining on modern machinery to provide high quality and low cost, to meet the exacting standards of our valuable customers.
