Design and Construction

O api 602 globe valve is known for its strong build. Its body is made from A105N forged steel. This makes the valve tough and long-lasting. The pressure rating is 2500LB, so it works well under high pressure. The DN50 size and butt-welded end help stop leaks. The pressure seal bonnet keeps the connection tight and leak-free. The rising stem with a handwheel lets you control the valve easily. The outside screw and yoke (OS&Y) design makes the valve more reliable. It also makes using the valve simpler. The valve is compact, so it fits in small spaces. It can handle high heat and pressure.

Here is a table with the main design features:

The api 602 globe valve has one sealing surface. This helps the valve seal tightly when closed. It lowers leaks and helps keep things separate. Maintenance is easier and needed less often because of this design.

Sealing and Materials

You want a valve that does not wear out or rust. The api 602 globe valve uses strong sealing materials. These help the valve work well in tough places. Reinforced flexible graphite seals well and fights corrosion. Stainless steel (SS 316) works with flexible graphite and also resists rust. Hard alloy is welded to the sealing surface. This makes the valve last longer in high heat and pressure.

Here are the usual sealing materials:

• Reinforced Flexible Graphite: Seals well and fights corrosion.
• Stainless Steel (SS 316): Resists rust, often used with flexible graphite.
• Hard Alloy: Very tough, welded to the sealing surface.

The api 602 globe valve works in many temperatures. The sealing materials let it handle -29°C to +425°C. You can use the valve in cold or hot places.

Connection Types

You have different ways to connect the api 602 globe valve. The butt-welded end is common, but you can pick other types. The connection ends follow rules like ASME B16.5, EN 1092, and JIS 5K-20K. These rules make it easier to install the valve. They help you match the valve to your pipes. You can choose BW (butt weld) or RTJ (ring type joint) for a strong connection.

Here is a table with connection types and standards:

You can use the api 602 globe valve for water, oil, gas, and corrosive liquids. The valve meets rules like api 602, BS 5352, ANSI B16.34, and iso. Each valve is tested to api 598 rules. This means you get good performance every time.

API 602 Standard Requirements

The api 602 standard sets strict rules for globe valves like the 2500LB model. You need to know these rules to ensure your valve meets industry needs. The api 602 standard covers everything from design to testing. It helps you get a valve that works safely and reliably in high-pressure systems. You can trust valves that meet this standard because they go through detailed tests and inspections.

Testing and Inspection

You want your valve to work every time. The api 602 standard requires each valve to pass a series of tests. These tests check for leaks, strength, and performance. The main test for api 602 globe valves is the pressure test. This test uses water or air to make sure the valve holds pressure without leaking. The api 602 standard also calls for visual inspections and checks for proper assembly.

The api 602 standard points to api 598 for most test and inspection steps. This means your valve must pass the same tests used by top manufacturers around the world. Here is a table showing the main test and inspection requirements:

The api 602 standard also includes a pressure test for both the body and the seat. You get a valve that can handle high pressure and temperature. The tests and inspections make sure the valve is safe and ready for use.

Note: The api 602 standard requires standard compliance and certification before you install the valve in your system.

You can see that the api 602 standard uses api 598 as the main guide for testing. This ensures your valve meets global safety and quality rules. The api 602 standard also covers other important tests, such as the seat leakage test and the shell pressure test. These tests help you avoid leaks and failures in your system.

Here is a table that explains how api 598 testing protocols help you:

The api 602 standard makes sure your valve is ready for tough jobs. You can rely on these tests to keep your system safe.

Internal Components

The api 602 standard also lists the key parts inside the valve. Each part must meet strict rules for size, shape, and material. You get a valve that works well and lasts a long time. The api 602 standard covers the stem, disc, seat, and packing system.

Here is a table showing the main internal components and their roles:

You can see that the api 602 standard focuses on both safety and performance. The stem design gives you dual sealing. The disc and seat shape help you get a tight shutoff. The packing system lets you use the valve in hot places without leaks.

The api 602 standard also requires that all internal parts pass a test for fit and function. You get a valve that opens and closes smoothly. The pressure test checks that the stem and seat hold pressure without leaks. The api 602 standard ensures every part works together for the best results.

Tip: Always check that your globe valve meets the api 602 standard before you buy or install it. This helps you avoid problems and keeps your system running safely.

Comparison with Other Standards

API 602 vs API 600

API 602 and API 600 are different standards. API 600 is for cast gate valves. These valves are used in big pipelines and refineries. API 602 is for forged globe, gate, and check valves. These work best in small, high-pressure systems. You use API 602 valves in power plants and process skids. These places have little space and need reliable valves.

Here is a table that shows how they are different:

| Feature — | API 600 — | API 602 — | | Valve Type — | Cast gate valve — | Forged gate, globe, and check valves — | | Size Range — | Usually 2” and bigger — | Usually 2” and smaller — | | End Connections — | Flanged and butt weld ends — | Threaded, socket weld, and flanged — | | Construction — | Bolted bonnet, cast body — | Forged body construction — | | Application — | Pipelines, refining, and petrochemical — | Power plants, skid units, compact piping — | | Body Material — | Cast carbon/stainless/alloy steels — | Forged carbon/stainless/alloy steels — | | Maintenance Access — | Easier, large bonnet openings — | More compact, a bit more complex — | | Pressure Handling — | Good for bigger system pressures — | Good for small high-pressure spots — | | Space Requirements — | Needs more space — | Fits in tight spaces — | | Cost — | Higher for bigger valves — | Lower for smaller valves — |

API 600 valves are found in refineries and oil pipelines. API 602 valves are used in power plants and chemical skids. If you need a valve for a small, high-pressure job, pick API 602. The biggest valve maker in europe sells both types. You choose the one that fits your system.

API 602 vs ASME B16.34

You might wonder how API 602 and ASME B16.34 compare. ASME B16.34 gives rules for pressure and temperature ratings. It also covers material properties. This standard is used in many industries. API 602 is for small forged globe valves. It makes sure these valves work well in tough places.

Here is a table that shows the differences:

| Aspect — | ASME B16.34 — | API 602 — | | Pressure-Temperature Ratings — | Detailed curves for many valve types — | Focuses on strength and sealing for small forged globe valves — | | Material Properties — | Broad framework for many industries — | Specific to high-pressure, high-temperature jobs — | | Testing Protocols — | Comprehensive for many applications — | Reliable in critical applications — |

ASME B16.34 gives you more design choices. API 602 gives better sealing and strength for hard jobs. The top shut-off valve maker in europe uses both standards. This helps you get safe and strong valves. If you need a valve for a special high-pressure job, pick API 602. For general use, look at ASME B16.34.
