Looking for a manifold valve supplier in the United States? Samvay manufactures 2 way, 3 way and 5 way manifold valves for pressure and DP transmitters, machined from certified bar stock.
Samvay Fluid Tekniks manufactures manifold valves at its Ahmedabad works and supplies them to the United States, where shale oil and gas and LNG export drive most instrumentation demand. US buyers order to ASME and ASTM standards, which are the base of our product design, so our fittings fit directly into US specs.
A manifold valve combines isolation, equalising and vent valves in one forged block, so a pressure or differential pressure transmitter can be isolated, calibrated and returned to service without breaking the process connection. In the United States the typical service is sour gas, cryogenic LNG and high pressure hydraulic service, 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 the United States
Service conditions in the United States usually mean sour gas, cryogenic LNG and high pressure hydraulic service. These are the grades we most often supply for that duty.
| Recommended grade | Why it suits the United States |
|---|---|
| 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 |
| SS 316 or carbon steel A105, heavy pattern | Vibration, dust and frequent remaking, where thicker bodies and hard seats last longer |

Frequently asked questions
Do you deliver manifold valves to Houston and Gulf Coast?
Yes. We ship by sea from Mundra or Nhava Sheva to Houston or New York in about 30 to 40 days, or by air. Regular consignments reach Houston, Gulf Coast, Permian Basin and Louisiana, 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 the United States?
For sour hydrocarbon service, where hardness control and sulphide stress cracking resistance are required, we usually recommend Duplex 2205 or Inconel 625 to NACE MR0175. Where conditions are milder, SS 316L with impact testing is a cost effective alternative. Share your process data and we will confirm the grade before quoting.
What certificates come with orders for the United States?
Orders for the United States are supplied to ASME B31.3, NACE MR0175, ASTM material specifications and DFARS compliant material on request. 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.
Which manifold configurations do you supply?
Our manifold valves are available in 2 way, 3 way and 5 way designs, in sizes from 1/2 inch, with pressure classes from 150# to 1500#, in stainless steel, duplex F51 and F53, alloy steel F11 and F22, Monel, Inconel and Hastelloy. Direct mount and remote mount versions are available, so transmitters on projects in the United States can be installed close to the process or on a stand.
