Nickel Alloy Instrumentation Valves are compact valves used to isolate, regulate or direct flow in instrument, control and sampling lines. This page focuses on commercially pure Nickel 200 (UNS N02200) and low-carbon Nickel 201 (UNS N02201). Both grades offer useful resistance in many reducing and caustic environments. Nickel 201 is generally preferred when prolonged service exceeds about 315°C because its lower carbon content reduces the risk of intergranular carbon or graphite embrittlement.
Kalpataru Piping is a manufacturer, supplier and exporter of Nickel 200/201 instrumentation valves in needle, ball, manifold, root/isolation and check-valve configurations, subject to design availability. Valve selection should be based on fluid chemistry, pressure, temperature, connection type, seat or seal material and the governing project specification.
Typical duties include gauge and transmitter isolation, pressure-instrument take-offs, sampling panels, analyzer systems and other small-bore process instrumentation. For instrument-valve applications, MSS SP-99 and ANSI/MSS SP-105 are the most directly relevant standards in their stated scope; ASME B16.34 and other connection or test standards should be cited only when the specific valve design or project specification actually requires them.

Applicable Standards for Nickel Instrumentation Valves
| Applicable Standard | Primary Requirement | Relevant Nickel Instrumentation Valve Types |
|---|---|---|
| MSS SP-99 | Primary standard practice for small valves and manifold valves used in instrument, control and sampling piping systems; scope includes NPS 2 and smaller and pressure ratings up to 15,000 psi at 100°F (38°C). | Needle, ball, manifold, root/isolation and other instrument-valve designs that fall within MSS SP-99 scope |
| ASME B16.34 | Applies to flanged, threaded, welding-end and certain wafer/flangeless valves when the selected valve design falls within ASME B16.34; it is not a blanket instrumentation-valve standard. | Only applicable valve designs whose construction and end connections fall within ASME B16.34 scope |
| ANSI/MSS SP-105 | Instrument-valve standard for code applications; applies to small valves and manifolds used in instrument, control and sampling piping systems, NPS 2 and smaller, up to 15,000 psi at 100°F (38°C). | Instrument valves and manifolds used in code piping applications within the standard's stated scope |
| ASME B16.5 | Covers pipe flanges and flanged fittings. Use it for the flange connection where applicable; it does not by itself qualify the instrumentation valve body. | Flanged-end valve connections where the flange design is within ASME B16.5 scope |
| ASME B16.25 | Covers preparation of buttwelding ends of piping components. Use only where the selected valve is actually supplied with butt-weld ends. | Butt-weld-end valves where the connection preparation follows ASME B16.25 |
Kalpataru Piping supplies Nickel 200/201 needle, ball, manifold, root/isolation and check valve designs for instrumentation service, subject to size, pressure and connection availability. Gate and butterfly valves should be treated as separate process-valve products rather than grouped under instrumentation valves.

FAQs About Nickel 200/201 Instrumentation Valves
What is the difference between Nickel 200 and Nickel 201 instrumentation valves?
The main material difference is carbon content. Nickel 200 permits up to 0.15% carbon, while Nickel 201 is limited to 0.02%. Nickel 201 is generally preferred for prolonged service above about 315°C because its lower carbon content reduces the risk of intergranular carbon or graphite embrittlement. Final valve selection must also consider media, pressure, seal material and the valve design.
What pressure ratings are available for Nickel 200/201 instrumentation valves?
Pressure rating is design-specific. MSS SP-99 and ANSI/MSS SP-105 cover instrument valves and manifolds through NPS 2 with pressure ratings up to 15,000 psi at 100°F (38°C). Higher-pressure products, including any 20,000 psi design, should be quoted only against the manufacturer’s certified pressure-temperature rating and project requirements.
Which standards apply to Nickel 200/201 instrumentation valves?
MSS SP-99 is directly applicable to small instrument valves and maniWhat sizes can Nickel 200/201 instrumentation valves be supplied in?
What information should I send for a valve quote?
Send the nickel grade, valve type, size, connection, working pressure, design temperature, process media, quantity and the required standard or inspection documentation. This allows the pressure-temperature rating, seal system and material suitability to be checked before quotation.
