A Hastelloy Manifold Valve is the first line of defence wherever process fluids are aggressive, temperatures swing between cryogenic lows and 500 °C, and a single leak can shut down an entire plant. Kalpataru Piping Solution manufactures and exports a complete range of Hastelloy Manifold Valves in C276 and C22 grades, covering 2-way, 3-way, and 5-way configurations in R-Type, T-Type, and H-Type body designs. Each valve is bar-stock forged from ASTM B574/B575 certified material, pressure-tested up to 15,000 PSI, and 100 % helium-leak-tested before dispatch.
Our manifold valves are used to isolate, vent, and equalise differential-pressure transmitters in oil refineries, chemical plants, offshore platforms, power stations, and pharmaceutical facilities. They replace the need for separate tubing and fittings, reducing potential leak points by up to 60 %. With metal-to-metal bonnet-to-body seals, burr-free threads, and an optional direct-mount or remote-mount configuration, Kalpataru valves meet or exceed the performance of Swagelok, Parker, and Rosemount equivalents — at a competitive Indian manufacturing cost.

What Is a Hastelloy Manifold Valve?
A manifold valve is an integrated valve block that combines two or more shut-off functions — isolation, equalization, and venting — into a single forged body. When that body is machined from Hastelloy (a family of nickel-molybdenum-chromium superalloys), the assembly gains outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking in chloride-rich, oxidising, and reducing media.
Why Hastelloy?
- C276 grade (UNS N10276 / DIN 2.4819): the industry workhorse for hydrochloric acid, wet chlorine gas, and mixed acid environments. Its high molybdenum content (15–17 %) makes it uniquely resistant to chloride-induced pitting and the widest range of process chemicals.
- C22 grade (UNS N06022 / DIN 2.4602): superior to C276 in oxidising environments (nitric acid, nitric-hydrofluoric mixtures, oxidising chloride solutions) due to higher chromium content (20–22 %) and excellent weldability.
Both grades retain mechanical integrity from –120 °C (cryogenic) to 500 °C, resist scaling at 650 °C, and can be heat-treated for use in hydraulic manifold systems.
Kalpataru Piping Solution stocks and custom-manufactures these valves alongside our broader range of Hastelloy Valves, Stainless Steel Manifold Valves, and Inconel Valves for complete instrumentation loop solutions.

Types of Hastelloy Manifold Valves
By Number of Ways
Type | Function | Typical Use |
|---|---|---|
2-Way Manifold Valve | Isolation only | Single-port instruments, gauge isolation |
3-Way Manifold Valve | Isolation + equalisation | Differential pressure transmitters, flow meters |
5-Way Manifold Valve | Isolation + equalisation + venting | DP transmitters requiring in-place calibration |
5-way vs. 3-way: A 5-way manifold adds a dedicated vent tube to a safe or inaccessible area, enabling in-place transmitter calibration without breaking the process connection — the preferred choice for hazardous-fluid service.
By Body / Configuration Type
- R-Type (Remote Mount): Valve block connected to the transmitter via tubing and compression fittings. Uses standard instrument manifolds; easier installation in tight spaces.
- T-Type (Top-Entry): All valve stems access from the top; suited for panel-mounted setups.
- H-Type (In-Line / Horizontal): Process and instrument connections on the same horizontal axis; minimises installation height.
By Mounting Style
- Direct Mount Manifold — fewer leak points, less expensive installation, integrated valves; system is still hard-piped to the transmitter.
- Remote Mount Manifold — piping mounted on the transmitter; uses standard manifolds and tubing/fittings; easier maintenance.

Hastelloy C276 vs C22 Manifold Valve — Which Grade Should You Choose?
Property | Hastelloy C276 (UNS N10276) | Hastelloy C22 (UNS N06022) |
|---|---|---|
DIN / Werkstoff Nr. | 2.4819 | 2.4602 |
Ni content | Balance | Balance |
Cr content (%) | 14.5 – 16.5 | 20 – 22 |
Mo content (%) | 15 – 17 | 12.5 – 14.5 |
Fe content (%) | 4 – 7 | 2 – 6 |
Best corrosion resistance | Reducing acids, chloride pitting, wet chlorine | Oxidising acids (HNO₃), mixed oxidising–reducing media |
Stress-corrosion cracking | Excellent | Superior |
Weldability | Good | Excellent |
Cryogenic use | Yes (–120 °C) | Yes (–120 °C) |
Max service temperature | 500 °C | 500 °C |
Tensile strength | ~790 MPa | ~690 MPa |
Melting point | 1,370 °C | 1,399 °C |
Typical applications | Pulp & paper, HCl service, offshore oil & gas | Pharmaceutical, nitric acid plants, flue-gas desulphurisation |
ASTM standard | B574 (bar), B575 (sheet) | B574 (bar), B575 (sheet) |
Rule of thumb: choose C276 for strongly reducing chloride environments; choose C22 when the process alternates between oxidising and reducing conditions, or when mixed acid media is present.

Hastelloy Manifold Valve - FAQs
A Hastelloy Manifold Valve is used to isolate, equalise, and vent differential-pressure instruments — such as pressure transmitters and flow meters — in process plants. It consolidates multiple valve functions into one forged block, reducing leak points and simplifying maintenance. Hastelloy grades are chosen when the process fluid is corrosive (acids, chlorides, wet chlorine) and standard stainless steel would fail prematurely.
A 3-way manifold valve provides two isolation valves and one equalising valve — enough to isolate a DP transmitter and equalize pressure across it for calibration. A 5-way manifold adds two additional vent/calibration valves, allowing the transmitter to be calibrated in place without removing it from the process line. The 5-way is preferred when the process fluid is hazardous or when frequent in-situ calibration is required.
Kalpataru Piping Solution manufactures Hastelloy Manifold Valves in five standard pressure ratings: 1,500 PSI, 3,000 PSI, 6,000 PSI, 10,000 PSI, and 15,000 PSI. The maximum standard working pressure for the 3-way R-type body is 6,000 psig at 100 °F (414 bar at 38 °C); higher ratings are available in special forged configurations.
Yes. Both C276 and C22 grade Hastelloy maintain adequate ductility and mechanical properties down to –120 °C, making them suitable for cryogenic LNG and liquid nitrogen service. However, the pressure rating should be de-rated per the manufacturer’s pressure-temperature chart for the specific temperature.
Every valve ships with a Mill Test Certificate (MTC) to EN 10204 3.1, a dimensional inspection report, and hydrostatic / pneumatic test certificates. PMI (Positive Material Identification) reports, NABL-accredited lab reports, and third-party inspection by TUV / SGS / Bureau Veritas are available on request.
