Kalpataru Piping Solution supplies valve manifolds, the 2, 3 and 5-valve blocks that isolate, equalise and vent a pressure instrument in one compact unit. The busiest lines are the stainless steel 304 manifold valves and Inconel 625 manifold valves, part of our full Valves range. A manifold replaces a set of separate valves and fittings on a gauge or transmitter hook-up with one leak-tested block, and each routes to its grade below.
The configuration follows the instrument: a 2-valve manifold isolates and vents a pressure gauge, while 3-valve and 5-valve manifolds add the equalising valve a differential-pressure transmitter needs. The grade follows the process, from stainless up to duplex S31803/S32205 manifold valves and Hastelloy, and the manifold pairs with the matching instrumentation tube fittings so the hook-up stays one material.
2, 3 & 5-Valve Manifolds
| Configuration | Valves | Used for |
|---|---|---|
| 2-valve manifold | One isolate + one vent/test | Pressure gauges and single-line pressure transmitters |
| 3-valve manifold | Two isolate + one equalise | Differential-pressure transmitters, letting the DP cell be zeroed safely |
| 5-valve manifold | Two isolate + two vent + one equalise | DP transmitters needing full isolation, venting and calibration |
Manifolds by Grade
| Grade | Best for | Go to |
|---|---|---|
| Stainless 304 / 316L / 310 | General and high-temperature instrument service | 304 / 316L / 310 manifolds |
| Inconel 625 / Incoloy 825 | High temperature and aggressive corrosion | Inconel 625 manifolds |
| Duplex / Super Duplex | High-chloride and seawater instrument lines | Duplex manifolds |
| Hastelloy C276 | Wet chlorine and mixed acids | Hastelloy C276 manifolds |
| Titanium Gr2 / 254 SMO | Seawater and high-chloride service | Titanium / 254 SMO manifolds |
We hold Incoloy 825 manifold valves, stainless steel 316L manifold valves, titanium Gr2 manifold valves, Hastelloy C276 manifold valves and 254 SMO manifold valves across the range.
Where Manifolds Fit in the Hook-Up
A manifold sits directly between the process impulse lines and the instrument, so it bolts to the transmitter flange on one side and connects to the impulse tubing through instrumentation tube fittings on the other. Keeping the manifold, the fittings and any isolation ball valve to one grade means the whole hook-up is a single material with one certificate trail. The full Valves range carries the ball, needle and monoflange patterns that complete the assembly.
