Kalpataru Piping Solution supplies instrumentation ball valves for quick quarter-turn isolation on instrument and small-bore lines, in the grade range corrosive service demands. The busiest line is the Hastelloy C276 ball valves for aggressive acid and chloride duty, alongside stainless steel 316 ball valves for general instrument service. These are part of our full Valves range, and each routes to its grade below. Every valve is pressure tested before dispatch.
A ball valve gives a tight, fast on/off shut-off with a simple quarter-turn, which is why it is the standard isolation valve on gauge, transmitter and sampling hook-ups. The grade is chosen for the process chemistry, from stainless steel 304 ball valves for general work up to Alloy 20 ball valves and Hastelloy for acids, and it pairs with the matching instrumentation tube fittings so the hook-up stays one material.
Ball Valves by Grade
Grade first, because the ball, seat and body must survive the process chemistry.
| Grade | Best for | Go to |
|---|---|---|
| Stainless 304 / 316 | General instrument and process isolation | 304 / 316 ball valves |
| Hastelloy C276 / C22 | Wet chlorine, mixed and oxidising acids | Hastelloy C276 ball valves |
| Alloy 20 | Sulphuric acid service | Alloy 20 ball valves |
| Nickel 200 | Caustic and high-purity chemical service | Nickel 200 ball valves |
| Copper Nickel 90/10 | Seawater and marine instrument lines | Copper nickel ball valves |
| PTFE / Teflon | Chemically inert, non-metallic seat and body | PTFE ball valves |
We also hold stainless steel 347 ball valves and Hastelloy C22 ball valves among the wider grade range.

Where Ball Valves Fit in the Hook-Up
A ball valve is the isolation point of an instrument hook-up. Paired with the instrumentation tube fittings and, where fine control is needed, a needle valve, it makes up the run from the process take-off to the gauge or transmitter. Keeping the ball valve, the fittings and any manifold to one grade means the hook-up does not mix metals at a joint. The full Valves range carries the needle, manifold and monoflange patterns that complete the assembly.
