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. These needle valves are an ideal option for isolating or throttling applications. The self centering, non rotating stem ensures perfect seating. The rigid design gives repetitive bubble tight shut off, easy.
We are the trusted name in the industry when it comes to the manufacture and supply of valves, fittings and industrial couplings with adapters. We have served a wide variety of industrial sectors, and supply products which conform to industry standard requirements and ensure safety and system efficiency with their precision design. We offer an extensive product portfolio, and are also trusted manifold valve manufacturers, who offer reliable products for high end system efficiency. We understand the importance of durable quality in industrial valve and fitting design, and that is why we never compromise on quality.
With rich expertise, we are offering a wide range of Needle Valves that is generally used in flow metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time, such as the idle fuel flow in a carburetor. Our needle valves are appreciated in the market for low operating torque and high tensile strength. Further, these are provided in proper packaging to the clients in order to prevent wear and tear during transportation. Needle Valves or Shut-Off Valves are designed to Isolate, Calibrate and Drain Process Lines by Line Mounting.
