2" Floating Ball Valve | ASTM A216 WCB | Class 150 | RF Flanged | API 607 Fire Safe

In industrial piping systems, valves not only perform the functions of opening, closing and regulating fluids, but also directly affect the safety, stability and maintenance costs of the entire system. For fluid control applications in petroleum, natural gas, chemical, power generation and general industrial sectors, a valve with reliable structure, excellent sealing performance and fire-safe capability is often a key consideration in engineering selection.

This 2-inch floating ball valve features an ASTM A216 WCB carbon steel body, a Class 150 pressure rating, RF flanged connection, and complies with API 607 fire-safe requirements. It delivers an optimal balance of economy, durability and safety, making it a common and practical valve solution for numerous industrial projects.

I. Core Product Advantages

1. Floating ball structure for stable sealing performance

   The ball of a floating ball valve is pressed against the downstream seat under medium pressure, creating a stronger seal. This structure is suitable for medium and low-pressure working conditions, providing reliable shut-off performance and reducing leakage risks.

2. ASTM A216 WCB body material ideal for industrial applications

   ASTM A216 WCB is a widely used cast steel material with good mechanical strength and machinability. It is suitable for petroleum, natural gas, steam, water and general industrial media, achieving an excellent balance between cost, strength and application scope.

3. Class 150 pressure rating meeting general industrial demands

   Class 150 is a standard pressure rating for industrial valves, applicable to various medium and low-pressure piping systems. It is highly versatile for conventional conveying, isolation and shut-off applications.

4. RF flanged connection for easy installation

   The RF (Raised Face) flanged connection is widely adopted in industrial piping, facilitating convenient installation, maintenance and replacement. Flanged connections also enhance overall system reliability, especially for applications requiring frequent servicing.

5. API 607 fire-safe certification for high-safety environments

   The API 607 fire-safe design ensures that the valve maintains a certain sealing capability under extreme conditions such as fire, minimizing the risk of medium leakage. This feature is particularly critical for flammable, explosive or high-safety industrial systems.

II. Applicable Industries & Scenarios

This 2" floating ball valve is widely used in the following fields:

• Oil and gas piping systems

• Chemical and petrochemical plants

• Refineries and storage & transportation systems

• Power and energy projects

• Industrial water treatment systems

• General fluid control pipelines

Thanks to its compact structure, easy operation and relatively low maintenance cost, it is especially popular in applications requiring quick shut-off and reliable sealing.

III. Why Choose This Ball Valve

This valve is an ideal choice if your project demands standard compliance, convenient on-site maintenance and long-term operational stability.

Its advantages extend beyond material and pressure rating to the practicality of its overall design:

• Simple structure with low failure rate

• Fast operation with low operating torque

• Reliable sealing suitable for frequent cycling

• Fire-safe design improving system safety level

• Flanged connection for easy system integration

It offers high selection value for engineering purchasers, equipment integrators and end-users.

IV. Importance of Quality & Standards

In industrial valve procurement, standards often deserve more attention than price.ASTM A216 WCB defines the material foundation, Class 150 specifies the applicable pressure range, RF flanged indicates the connection type, and API 607 Fire Safe directly relates to safety performance.

When these key parameters meet project requirements, the valve can more easily pass engineering inspections and simplify later maintenance and replacement.

V. How to Select the Right Floating Ball Valve

For proper selection, the following parameters are recommended for priority consideration:

• Nominal size: 2 inches

• Body material: ASTM A216 WCB

• Pressure rating: Class 150

• Connection type: RF flanged

• Fire safety requirement: API 607

• Medium type: gas, liquid, slightly corrosive media

• Temperature and pressure range: confirmed according to working conditions

For projects involving higher pressure, larger sizes or special media, further comparisons can be made among trunnion ball valves, full-port ball valves, metal-seated ball valves and other alternatives.
