3000 PSI Instrumentation Fittings & Valves

A 3000 PSI instrumentation fitting or valve is a stainless-steel or nickel-alloy flow-control component qualified for a 3000 psi (≈207 bar) cold working pressure (CWP), the maximum non-shock working pressure at ambient temperature, for gauge, sampling, hydraulic and process-tapping lines. Crestflo supplies the full 3000 psi set: needle, ball, check, manifold, double block & bleed, bleed, gauge/root, metering, relief and monoflange valves, plus single- and double-ferrule compression tube fittings, in 316/316L through duplex and nickel alloys. Fittings are tested to ASTM F1387; valves are built to ASME B16.34 and API valve standards; both are available NACE MR0175 / ISO 15156-compliant with an EN 10204 material test certificate and a heat number on every part.

This is an instrumentation-grade scope: flow-control valves and compression tube fittings for gauge, sampling and process service, not hydraulic or plumbing brass ball valves. Ready stock for standard items, made-to-order for specials, 6–8 week delivery. Request a quote with your rating, alloy and end connection.

Also Known As: 3000 PSI Valve, 3,000 PSIG, 207 bar & CWP Designations

A 3000 psi component is specified many ways across drawings and datasheets. Engineers call it a 3000 psi valve, 3,000 psi valve, 3000 PSIG valve, 3000 psi rated fittings, or a 3000 psi CWP valve (cold working pressure). In metric callouts the same rating reads ≈207 bar, ≈20.7 MPa, or ≈211 kg/cm². Component-level names include the 3000 psi needle valve, 3000 psi ball valve (also called a high pressure ball valve), 3000 psi tube fittings or high pressure tube fittings, 3000 psi manifold, 3000 psi check valve / NRV, and 3000 psi double block & bleed (DBB). On this page all of these refer to instrumentation flow-control hardware in 316 stainless or higher alloy.

What "3000 PSI" Means on a Valve or Fitting: CWP vs Flange Class

Cold working pressure (CWP) is the maximum non-shock pressure a valve or fitting will hold at ambient temperature. It is the instrumentation valve pressure rating you specify on a datasheet, and the psi rating of a tube fitting is read the same way. A 3000 psi CWP rating is a common instrumentation tier, it is a component rating, not a flange class. Flange classes (150 / 300 / 600) are pressure-temperature ratings for flanged joints under ASME B16.34 and are a different system; a Class 300 flange and a 3000 psi CWP component are not the same thing. The CWP a component actually holds depends on the body alloy and derates as temperature rises. Values below are per applicable standard and are customizable to requirement.

The selector below maps each instrumentation component that meets 3000 psi service to its size range, typical end connections and body materials. Ratings are per the applicable ASME/ASTM standard for each product type and are customizable to requirement.

High-Pressure Needle Valves for 3000 PSI Gauge & Throttle Service

The high-pressure needle valve is the workhorse for 3000 psi throttling, gauge isolation and sampling. Angle, straight, multi-port and panel-mount patterns are offered from 1/16″ to 1″ with NPT, BSP or tube-fitting ends in 316/316L through Monel and Hastelloy C-276. See the needle valve page for full options.

High-Pressure Ball Valves & CWP Ball Valves for 3000 PSI in 316 Stainless

Full-port high-pressure ball valves rated to 3000 psi CWP and dedicated CWP-rated ball valves provide quarter-turn isolation for instrument and process lines. Both the 3000 psi ball valve and the high-pressure ball valve share the same body alloys and seat options; they are covered on the ball valve and CWP ball valve pages.

3000 PSI Check Valves & NRVs

Spring-loaded check valves / non-return valves (NRV) prevent backflow on 3000 psi lines. Cracking pressure and orientation are specifiable, see the check valve and NRV pages.

3000 PSI Manifolds & Double Block & Bleed (DBB) Valves

2-, 3- and 5-valve manifolds are rated to 10,000 psi and comfortably cover 3000 psi service, with a non-rotating tip and 100% seat and shell leak testing. Double block & bleed (DBB) valves are designed per ASME B16.34 with a working pressure up to 3,000 psi in flanged and screwed configurations. Explore the 3-valve manifold, monoflange valve and DBB valve pages.

3000 PSI High-Pressure Tube Fittings (Single & Double Ferrule Compression)

High-pressure tube fittings rated to 3000 psi, single- and double-ferrule compression tube fittings to 2″ (50 mm) OD, are tested per ASTM F1387 in 316/316L, nickel alloy and titanium. These are instrumentation fittings, not hydraulic or plumbing compression fittings. Both imperial and metric sizes ship. See the tube fittings hub.

3000 PSI Connections, Threads & End Options: NPT, BSP, JIC, Tube & Weld

Every 3000 psi valve and fitting is available across the standard instrumentation end connections, including 3000 psi threaded fittings with NPT, NPTF or BSP ends alongside tube, flare, weld and flanged options. Values are per the applicable thread and connection standard and are customizable to requirement.

Materials for 3000 PSI Service: 316/316L, Duplex 2205, Super Duplex & Nickel Alloys

Material choice sets corrosion resistance, temperature range and sour-service suitability at 3000 psi. Standard 316/316L handles most instrument service; duplex, super-austenitic and nickel alloys are selected for chloride, sour or high-temperature media. Compositions are per the governing ASTM specification; select to your media and temperature.

For sour (NACE) service, NACE MR0175 / ISO 15156-compliant materials and builds are available, see the sour-service selection guide and the NACE MR0175 standard.

3000 PSI Temperature Derating

A 3000 psi CWP rating applies at ambient temperature. As service temperature rises, the allowable working pressure derates according to the body alloy's pressure-temperature curve per ASME B16.34. 316/316L retains more of its rating at moderate temperature than at elevated temperature, while nickel alloys extend the usable envelope. Confirm the derated rating for your temperature against the applicable material curve; ratings are customizable to requirement.

Standards, Testing, Traceability & Certifications for 3000 PSI Products

Crestflo holds the standard approvals applicable to each product type: compression fittings are tested to ASTM F1387; valves and double block & bleed are built to ASME B16.34 and the applicable API valve standards; welded ends conform to ASME B16.11; NPT threads to ASME B1.20.1.
