High Pressure Needle Valve

We, Aira Euro Automation, are also a prominent Needle valve manufacturer in India since 1990. We provide Medium Pressure Needle Valve and Low Pressure Needle Valve in India. Needle Valves are generally used to control clean gases and fluids. Needle Valve Manufacturers have designed this valve from two types of body materials: one is Brass and the other one is Stainless Steel. Brass Needle Valves are used in drinking water applications, other non-chemical reacting liquids and non-corrosive fluids. When this valve is to be used for High Pressure media, the manufacturers use Stainless Steel as it is the best material for corrosive media and high pressurized gases. This material’s durability is long and it also sustains high temperatures.

High Pressure Needle Valve Manufacturer

Aira Euro Automation is a needle valve manufacturer and we use only high-quality materials for our valves. Our HNV-HP model High Pressure Needle Valve’s Body is made from Forged S.S. 304 / 316 and the Bonnet is made from S.S. 304 / S.S. 316. It comes in ¼” to 2” sizes with Screwed End BSP Connections (NPT Connection Available on request). It has a Bubble tight leakage and can sustain pressure up to 1000 PSI.

How Needle Valves work

As mentioned, needle valves are generally used to control the flow of clean gasses or fluids. They are also sometimes used as a shut-off valve. 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.
