API 600 Gate Valve Overview
API 600 Gate Valve Supplier,API 600 Gate Valve Factory
Hauptmerkmale
API 600 cast steel gate valves are strong and work well in tough places. Makers build these valves with a cast body and a bolted bonnet. This makes them last longer and stay strong. Most valves have flanged ends that fit ASME pressure classes from 150 to 1500. Some valves have butt weld ends for special setups.
The outside screw and yoke design lets people see if the valve is open or closed. This helps keep workers safe and makes fixing the valve easier. The body and bonnet are made with care so the valve seals tight and lasts a long time. Many API 600 gate valves have a non-rotating stem with Acme threads. This makes the valve easy to use and helps it last longer. Some valves have double Acme threads so they open and close faster.
A flexible wedge keeps the seat safe and helps the valve last longer. Hardfaced seat and wedge choices, like CoCr alloy, help stop wear and rust. For valves up to NPS 16 and Class 150, a one-piece bonnet helps parts line up and means there are fewer pieces. These valves come in sizes from 2 inches up to 64 inches.
Note: API 600 gate valves follow strict rules, so people trust them for important jobs.
Industrial Applications
Engineers and plant bosses pick API 600 cast steel gate valves for high pressure and heat. These valves are used in refineries, chemical plants, and power plants. They help shut off and control flow in pipes with oil, gas, steam, or chemicals.
People use these valves for:
- Shutting off main lines in oil and gas pipes
- Controlling processes in chemical plants
- Handling steam in power stations
- Water systems in big factories
The API 600 standard makes sure each valve can handle hard jobs and keep working well. This makes them very important for places that need to be safe and work well.
Evaluation Criteria
Quality Standards
Buyers want every valve to be high quality. Top Chinese makers follow api 600 and other api rules. These rules cover how valves are made and tested. Factories use special ways to check for leaks and strength. They also use tests like ultrasonic and radiographic testing. This makes sure each valve works well in tough places. Mill Test Reports (MTRs) help track all pressure parts. Good quality stops problems and keeps everyone safe.

Note: Chinese companies can change the china api 600 cast steel gate valve to fit special jobs. They can make different sizes or ways to open the valve.
Material Grades
Picking the right material is important for how long a gate valve lasts. Chinese makers use many cast steel types for different jobs. The most used grades are: ASTM A216 WCB (carbon steel), ASTM A217 WC6 and WC9 (alloy steel), ASTM A350 LCB and LCC (for cold places), ASTM A351 CF8, CF8M, CF3, CF3M (stainless steel), and ASTM A995 4A, 5A, 6A (duplex and super duplex stainless steel).
These materials make the valve strong, stop rust, and help it last longer. Kohlenstoffstahl is good for most jobs. Alloy steel works for high heat and pressure. Stainless steel stops rust in chemical and water jobs.
| Material Grade | Material Type | Typical Use Cases / Standards |
|---|
| ASTM A216 WCB | Kohlenstoffstahl | General service, API 600 |
| ASTM A217 WC6 | Alloy Steel | High temperature, API 600, API 6D |
| ASTM A217 WC9 | Alloy Steel | High temperature, API 600 |
| ASTM A350 LCB | Kohlenstoffstahl | Low temperature, API 600 |
| ASTM A351 CF8 | Edelstahl | Corrosive service, API 600 |
| ASTM A351 CF8M | Edelstahl | Corrosive service, API 600 |
| ASTM A995 4A | Duplex Stainless | Severe corrosion, API 600 |
Tip: Picking the best material grade helps the valve work well and last longer.
Design Options
Top Chinese companies give many design choices for the china api 600 cast steel gate valve. These choices help buyers pick the right valve for their needs and make it work better.
