Ganpat Metal Pvt. Ltd. supplies stainless steel instrumentation valve requirements for industrial process lines, pressure measurement, sampling systems and fluid control equipment. The product category covers SS 304, SS 316 and SS 316L material specifications for buyers sourcing stainless steel valves for instrumentation applications.
SS 304 is a chromium-nickel stainless steel used for general industrial service. SS 316 contains molybdenum for improved resistance to specific forms of corrosion, while SS 316L has a maximum carbon content of 0.030%, making it a common choice for welded equipment where reduced carbon content is required.

| Connection | Description |
|---|---|
| NPT | National Pipe Taper thread, commonly used in North American pipe connections |
| BSPT | British Standard Pipe Taper thread |
| BSPP | British Standard Pipe Parallel thread |
| Metric Thread | Metric thread connection specified by the equipment or project |
| Tube-End Connection | Connection for compatible instrumentation tubing and fitting systems |
| Socket-Weld Connection | Welded connection for compatible pipe and valve configurations |
| Flanged Connection | Flanged connection defined by the applicable dimensional standard |
NPT, BSPT and BSPP are different thread systems and must not be treated as interchangeable. For a published 316 stainless steel needle-valve series, ratings of 6,000 psi at 200°F and 4,000 psi at 464°F apply to that specific series and construction only.
Ganpat Metal supplies stainless steel instrument valves under the SS 304, SS 316 and SS 316L material specifications for industrial instrumentation requirements.
For specific grade requirements, the applicable product page provides a more focused route for technical specifications and procurement enquiries.
Also available: SS Bleed and Vent Valves for releasing trapped pressure or venting a connected instrument line.
Inspection and documentation may include Material Test Certificate, chemical composition report, Positive Material Identification (PMI) report when specified, dimensional inspection report, pressure test report, seat-leakage test report, visual inspection records, material traceability records and third-party inspection report when required.
SS 304 is commonly used for general industrial service. SS 316 and SS 316L are often selected where molybdenum content is required for improved resistance to specific forms of corrosion. The correct grade depends on the process medium, concentration, temperature and exposure conditions.
Ganpat Metal Pvt. Ltd. handles industrial material enquiries based on the grade, connection, operating conditions and documentation specified by the buyer. Buyers can provide the material grade, valve type, port size, connection standard, working pressure, temperature and quantity to receive a quotation based on the required specification.
Ganpat Metal holds ISO certification and MSME registration as part of its business and quality credentials.
