INTRODUCTION
────────────────────────────────────────

In modern Indian process industries, precise flow regulation is not a luxury—it is a necessity. Whether the application is in oil & gas pipelines, chemical dosing systems, steam lines, power plants, pharmaceuticals, refineries, or heavy engineering plants, accurate control over fluid flow directly impacts safety, efficiency, and operational cost. The Stainless Steel Flanged Needle Valve offered by Krishna Industries is engineered to meet these exacting requirements with reliability, durability, and long service life.

A needle valve is specifically designed for fine and accurate flow control. Unlike gate valves or ball valves, which are mainly used for on-off service, needle valves allow gradual opening and closing, making them ideal for throttling applications. When combined with a flanged end connection and stainless steel construction, the valve becomes suitable for high-pressure, high-temperature, and corrosive Indian industrial environments.

Krishna Industries, based in Ahmedabad, Gujarat, India, supplies high-quality Stainless Steel Flanged Needle Valves to factories, EPC contractors, OEMs, maintenance teams, and industrial traders across India. Our valves are designed keeping Indian operating conditions in mind—fluctuating pressures, variable temperatures, aggressive media, and long continuous duty cycles.

This product page provides a comprehensive overview of our Stainless Steel Flanged Needle Valve, covering construction details, materials, working principle, applications, advantages, installation guidance, maintenance tips, and frequently asked questions. The content is written specifically for Indian buyers looking for a dependable supplier within India, with ready availability, technical support, and consistent quality.

WHAT IS A STAINLESS STEEL FLANGED NEEDLE VALVE?
────────────────────────────────────────

A Stainless Steel Flanged Needle Valve is a precision flow control valve designed to regulate the flow of liquids or gases with high accuracy. The valve uses a slender, tapered needle-like disc that fits into a matching seat. By rotating the handwheel, the needle moves gradually in or out of the seat, allowing very fine adjustments to flow rate.

The flanged end connections allow secure bolting to pipelines as per standard flange dimensions, making the valve suitable for medium to large line sizes and high-pressure systems commonly used in Indian industries.

The stainless steel body provides excellent resistance to corrosion, oxidation, chemical attack, and high temperatures. This makes the valve suitable for a wide range of industrial fluids such as water, steam, oil, gas, chemicals, and process media.

CONSTRUCTION & DESIGN FEATURES
────────────────────────────────────────

The Stainless Steel Flanged Needle Valve supplied by Krishna Industries is built with attention to detail and functional reliability. Key construction features include:

• Valve Body: Precision-machined stainless steel body designed to withstand high pressure and temperature conditions.
• Needle (Disc): Hardened and finely tapered needle for accurate flow regulation and long service life.
• Seat: Precisely machined seat ensuring tight shut-off and minimal leakage.
• Bonnet: Robust bonnet design for pressure containment and easy maintenance.
• Stem: Stainless steel stem with smooth threading for precise control and reduced wear.
• Packing: High-quality packing material to prevent leakage from the stem area.
• Handwheel: Ergonomically designed handwheel for smooth and controlled operation.
• Flanged Ends: Standard flanges compatible with Indian pipeline systems.

The design ensures minimal vibration, stable throttling, and repeatable performance over long operating cycles.

────────────────────────────────────────
MATERIAL SPECIFICATIONS
────────────────────────────────────────

The choice of stainless steel ensures durability and corrosion resistance. Common material options include:

• Body & Bonnet: Stainless Steel (SS 304 / SS 316 / SS 316L as required)
• Stem & Needle: Stainless Steel
• Seat: Stainless Steel or hardened alloy (as per application)
• Packing: PTFE / Graphite (based on temperature and pressure)
• Bolting: High-tensile stainless steel or alloy steel

Material grades can be selected depending on the media, temperature, and pressure requirements of Indian industrial applications.

────────────────────────────────────────
WORKING PRINCIPLE
────────────────────────────────────────

The working principle of a needle valve is simple yet highly effective. When the handwheel is turned clockwise, the stem moves downward, pushing the needle into the seat and gradually restricting the flow path. This allows precise control over the flow rate. Turning the handwheel counter-clockwise lifts the needle away from the seat, increasing the flow opening in a controlled manner.

Because the needle moves in small increments, the valve provides fine throttling control, making it ideal for applications where accurate flow adjustment is critical.
