Samvay Fluid Tekniks manufactures needle valves at its Ahmedabad works and supplies them to Surat in Gujarat, India, where petrochemicals at Hazira and LNG terminal drive most instrumentation demand. Hazira's petrochemical, steel and LNG complex near Surat uses large volumes of instrument valves rated for sour service.
A needle valve uses a fine tapered stem to throttle or isolate small flows with precise control, which makes it the standard choice for isolating gauges, transmitters and sampling points. In Surat the typical service is coastal corrosion and hydrocarbon service at Hazira, so grade selection and documentation matter as much as price. Every order ships with heat traceable material and a test record.

Choosing the right grade in Surat
Service conditions in Surat usually mean coastal corrosion and hydrocarbon service at Hazira. These are the grades we most often supply for that duty.
| Recommended grade | Why it suits Surat |
|---|---|
| Super duplex 2507 or S32760 | High chloride air and seawater, where PREN above 40 resists pitting and crevice corrosion |
| Duplex 2205 or Inconel 625 to NACE MR0175 | Sour hydrocarbon service, where hardness control and sulphide stress cracking resistance are required |
| SS 316L with impact testing | Low temperature and cryogenic duty, with Charpy test results on request |

Frequently asked questions
Do you deliver needle valves to Hazira and Sachin GIDC?
Yes. We ship by road dispatch from our Ahmedabad works in 1 day. Regular consignments reach Hazira, Sachin GIDC, Pandesara and Ichchhapor, and mixed orders of valves, fittings and accessories can be consolidated into one shipment with a single set of documents.
Which material grade do you recommend for projects in Surat?
For high chloride air and seawater, where PREN above 40 resists pitting and crevice corrosion, we usually recommend Super duplex 2507 or S32760. Where conditions are milder, Duplex 2205 or Inconel 625 to NACE MR0175 is a cost effective alternative. Share your process data and we will confirm the grade before quoting.
What certificates come with orders for Surat?
Orders for Surat are supplied to NACE MR0175, ASME B31.3 and EN 10204 3.1. Every part is heat marked and traceable to its mill certificate, and third party inspection by the agency of your choice can be arranged before dispatch.
What pressure ratings and end connections are available?
Our needle valves are rated at 1500, 3000 and 6000 psi, in sizes from 1/2 inch to 4 inch (DN15 to DN100), with NPT, PT and BSPP threads or socket weld, flanged and clamped ends. Two way, three way, four way and five way patterns are available, so one supplier can cover root valves, gauge isolation and manifold duties on the same project in Surat.
