The illustrated Class 600 flanged ball valve is the cast-body version with a fixed-ball arrangement. Forged-body alternatives are available for inquiry. Confirm the body grade, seats and operating device for the selected construction.
class 600 ball valve
- Leak-proof valve stem
In order to prevent the valve stem from flying causing abnormal internal pressure rise of the valve, the shoulder is fixed on the lower part of the stem. Confirm any fire-test qualification against a traceable report applicable to the supplied valve configuration; the stem sealing arrangement alone does not establish a leakage or accident-prevention guarantee.
- Key locker
The lock can be used to lock the manual valve when it is fully open or closed, preventing shutdown personnel from handling, which may cause the action of the valve. The locking device does not provide protection against electric shock and does not replace the applicable isolation, lockout/tagout or electrical safety procedures.
API ANSI ASME Class600 Ball Valves
- Fire safety structure
When the trunnion ball valve is in normal use, its capped seat and spherical method, seat retainer o-ring and stamped body, which is soft seal, reliable sealing when the seat and o-ring are damaged, seat retainer and The body will be stamped with expanded graphite which acts for fire safety purposes.
- Anti-static equipment
In order to prevent the friction between the ball, stem and PTFE to generate static electricity that may ignite flammable materials and explosives, causing accidents, in this ball valve, the static conduction spring is between the stem and the ball, the stem and the body, the actual electrical continuity, grounding arrangement and applicable anti-static verification requirements must be confirmed for the selected assembly; this feature alone does not guarantee system safety.
600LB flanged ball valve
- Leak free body seal structure
Smooth, the switch position of the valve body and bonnet double cap gasket and o-ring, on this basis, such reasons as fire, high temperature, shock absorption and uneven opening or closing torque will not cause Outer leaks.
- Double Block Bleeding (DBB)
When the ball is in the fully open or closed position, the transmitter material body can be released from the center of the cavity to drain and drain the device. In addition, very central pressure inside the valve cavity can be released to low pressure over its own rescue seat.
- Emergency seal
Composite injection hole design and composite injection valve installed on the stem/cap and body side of the support valve when the seal stem or seat is damaged to induce leakage, this compound can be used as a second seal for concealed check valves There are composite injection valves installed beside it to prevent the compound from flowing out due to the action of the substance, the injection valve on the top of the transmitter composite and the composite quick connect connector to the injection gun.
- Reduce the recess of the automatic valve body
When the body pressure rises abnormally, such as unstable factors, the downstream seat of the trunnion ball valve will be under normal pressure, and the abnormal pressure will be automatically released at the same time, without damaging the seal of the upstream seat.
- Various drive types-class 600 ball valve
The valve top pad is designed according to ISO 5211, which is convenient for communication and connection of various drives. The common drive types are manual, electric, pneumatic, pneumatic/hydraulic.
Chinese Flanged ball valve made in China
The illustrated Class 600 flanged ball valve has a cast body. A forged-body version can also be requested. These are alternative constructions, so material grades, dimensions and documentation must correspond to the version actually ordered.
Product Overview
Select cast or forged construction from the process requirements and approved project specification, not from a general material list. The body, ball, stem, seats and seals must be confirmed as one assembly. Claims about fire testing, double isolation or relief arrangements require model-specific documentation and should not be inferred from construction method.
Selection and Ordering Notes
- Identify cast or forged construction and the required Class 600 configuration.
- Confirm body grade, trim, seat and seal specification and the complete pressure-temperature rating.
- Provide size, flange details, operation and installation-space requirements.
- Request the actual inspection, fire-test or isolation documentation required by the project rather than assuming a qualification from the product title.

Frequently Asked Questions
Is the valve in the image cast or forged?
The illustrated valve is the cast version. A forged version is available for inquiry; request a drawing and material specification that match the construction you intend to order.
Can I use the same material grade for cast and forged bodies?
Specify the construction and the corresponding material specification separately. Do not assume that a cast-material designation and a forged-material designation are interchangeable.
Does a Class 600 or forged-body description prove fire-safe or double-block performance?
No. If those functions or qualifications are required, identify the acceptance standard and obtain documentation for the actual valve design and configuration.
