Needle & Ball Valves

Mcneil Instrument Inc. make Needle valves come in bar stock as well as in forged construction various sizes, sealing styles, end connections and stem types. Main feature of Needle valves is that its stems are interchangeable with any of its valves of the similar configurations thus resulting in low cost and less inventory.We offer a range of needle valve that are fabricated from qualitative raw material and are as per the international standards.

Needle Valve
10,000 PSI Needle Valves with screwed bonnet, integral seat and threaded pipe ends as per ANSI B 1.20``.1. Applications are for throttling and straight shut-off.

They are designed in varied sizes ranging 1/8 To 2(3 mm To 50 mm) and are designed as:

5-way manifold valve: Developed for remote mounting, a 5-way manifold valve typically has 2 drain valves, 1 equalizer and 2 isolate valves. This uncomplicated 5 valves arrangement assists in easy isolation and vent valve regulation of a static pressure receiver. Given below are some unique features of this valve:

    • Straight and angle pattern
    • Precision machined stainless steel stem
    • Rugged and Compact Square forged body
    • Longer life with minimum maintenance
    • Low operation torque
    • Valves with double ferrule tube fittings
