Alloy Steel Needle Valves

At Instinox, we believe that is not valid to cover a twenty-foot long road in just two ten foot jumps i.e. one has to follow some inimitable processes. Since two decades, we are and will continue to create memoirs. We believe that great recognition comes with great efforts. Our manufacturing team, our logistics team, our merchandisers all around the world have worked with great coordination, to become the topmost manufacturers and suppliers of Alloy Steel Needle Valves. We specialise in the making of alloy steel needle valves. Our aim of ‘high quality, low prices’ has surely made us stand out from the crowd. We are an ISO Certified firm and have successfully fulfilled all industry regulations. Being one of the most popular Indian manufacturers, as rated by the industry, we assure you of repetitive orders and our strategy of never compromising on the quality of the products. We have an extremely efficient manufacturing and logistics team, who provide with customised making, packing and packaging according to the client requirements.

Applications like flow metering applications use needle valves, especially when a consistent, measured, low flow rate must be upheld for some time, such as the stagnant fuel flow in a carburettor. Needle valves are used in changing the direction of the flow.
Note that the float valve of a carburettor (controls the fuel level within the carburettor) is not a needle valve, although it is described as one. It uses a blunt conical needle, but it seats against a square edged seat rather than a matching cone. The aim here is to obtain a well-defined set between 2 narrow joining surfaces, giving firm shutoff of the outflow from only a light float pressure. Since flow rates are less and many bends of the valve stem are required to fully open or close, needle valves are not used for simple on the go applications.
The force advantage of the fine threaded stem is more since the opening is narrow. Needle valves are usually easy to shut off completely, with solely finger tight pressure. The spindle of a needle valve made from brass, when shutting off the flow can be easily damaged by extra turning force. Small simple needle valves are often used as bleed valves (hydraulic valves that combine one or more block/isolate valves,) in water heating applications. It is not easy to tell from examining the handle position and check whether the valve is open or closed, unlike a ball valve or valves with a rising stem.

An alloy steel needle valves manufacturers uses a tapered (reduce in thickness towards one end) pin to slowly open up space for subtle control of flow. The flow can be controlled and regulated with the use of a spindle (a slender rounded rod with tapered ends). An alloy steel needle valves suppliers has a comparatively small opening with a long, tapered seat, and a needle-shaped plunger (part of a device or mechanism that works with a plunging) on the end of a screw, which exactly fits the seat. As soon as the screw is turned and the plunger retracts, flow is possible between the seat and the plunger, however, until the plunger is completely retracted, the fluid flow is significantly impeded. Since it takes many spins of the fine threaded screw to retract the plunger, precise regulation of the flow rate is possible. The specification of the needle valve is from the vernier (a vernier scale is a device that lets the user measure more precisely than it could be done unaided when reading a circular measurement scale) effect of the ratio between the needle’s length and its diameter, or the difference in diameter between needle and seat. A long travel axially (control input) makes for a very small and significant change radially (affecting the resultant flow). Needle valves may also be used in vacuum cleaner systems, when a specific control of gas flow is required, at low pressure, such as gas filled vacuum tubes, gas lasers and similar devices. We are our merchandisers, who have helped us in gaining an advantage and a trusted brand in the whole market. Here, you just place the order, and we are there to look after the rest.

We are an ISO 9001:2008, an ISO 14001:2004, and also an OHSAS 18001:2007 certification. We have our merchandisers all around the world, which provide with customised packing and packaging according to the client requirements. Just place the order, and we are there to worry about the rest. Due to our high-quality techniques, we have an overwhelming record of less than one percent rejection rate, as we follow a hundred percent in house checking of goods before doing it any further. We provide a perfect deal of your money and time. We value our employees as much we value our customers. Just place the order, we are there to worry about the rest procedures. Instinox is consistently engaged in exploring new and unique ways to become the monopoly in the industry.
