Main Dimensions

Valve Construction and Material Selection

The valve uses a stainless steel body with ASTM A351 CF8M (316) construction, while the ball and stem are specified as ASTM A182 F316. These materials provide a consistent stainless steel configuration for the pressure boundary and main wetted components. The RPTFE seat, consisting of PTFE with 15% filler, is selected for the stated operating range and should be confirmed against the actual process medium and temperature before ordering.

Stainless Steel Body

The ASTM A351 CF8M (316) body forms the main pressure-containing structure of the valve. Stainless steel construction can be considered for industrial media where material compatibility and corrosion resistance are important selection factors.

316 Ball and Stem

The ball and stem use ASTM A182 F316 material according to the listed configuration. The ball provides the quarter-turn flow-control element, while the stem transfers the operating torque from the handle or actuator to the ball.

RPTFE Seat

The RPTFE seat provides the sealing interface around the ball. Seat selection should be checked against the medium, operating temperature, pressure, and required service conditions because valve seat compatibility can vary between different process fluids.

Class 300 Flanged Ball Valve Configuration

The Class 300 configuration is intended for piping systems requiring a higher pressure class than Class 150. The listed maximum pressure is 740PSI, but the allowable working pressure should not be determined from the nominal class alone. Actual pressure capability depends on valve size, material, temperature, and the applicable pressure-temperature rating.

The RF flanged ends provide a bolted connection to matching pipeline flanges. During selection, the nominal pipe size, flange dimensions, pressure class, facing type, gasket arrangement, bolt specification, and available installation space should all be checked against the piping system.

ISO 5211 Actuator Mounting

The ANSI 300LB Flanged Ball Valve with ISO 5211 Base for Actuator can be configured for automated operation through its ISO 5211 mounting interface. The actuator should be selected according to the valve operating torque and actual service conditions rather than by valve size alone.

Pneumatic and electric actuators can be considered for automated on/off control. Depending on the control system, additional components such as solenoid valves, limit switches, position feedback devices, or positioners may be required. The available mounting interface, actuator torque, rotation angle, power or air supply, and control signal should be confirmed before assembly.

Manual Operation

Manual operation can be used where the valve is operated locally and automatic control is not required. The operating method should be selected according to valve size, installation position, operating frequency, and required operating torque.

Pneumatic Actuation

Pneumatic actuation is suitable for systems where compressed air is available and rapid quarter-turn operation is required. Actuator torque should include an appropriate allowance for the valve's operating conditions and seat friction.

Electric Actuation

Electric actuation can be used when the valve needs to be integrated into an electrical control system. Voltage, duty cycle, torque, travel limits, feedback requirements, and environmental conditions should be confirmed during actuator selection.

Production Process

1. Technical Confirmation

Before production, the required valve size, Class 300 rating, body and trim materials, working medium, temperature, seat configuration, connection dimensions, operating method, and actuator requirements are reviewed. Drawings and technical specifications can be checked when the valve is part of a larger piping or automation project.

2. Material Preparation and Inspection

Incoming materials and purchased components are checked according to the applicable production and inspection requirements. Material identification, dimensions, surface condition, and supporting material documentation can be reviewed for orders requiring traceability.

3. CNC Machining

CNC machining is used for valve body interfaces, flange surfaces, ball and stem components, sealing areas, bolt holes, and other precision features. Dimensional control is important for maintaining proper alignment between the valve body, pipeline connection, and operating components.

4. Component Preparation

Valve balls, sealing surfaces, stems, seats, packing, gaskets, fasteners, and other components are prepared before assembly. Surface finishing and cleaning requirements depend on the material and intended application.

5. Assembly and In-Process Inspection

Internal components are assembled according to the specified configuration. Checks can include stem alignment, ball movement, sealing component installation, flange dimensions, body assembly, and actuator mounting interface dimensions.

6. Pressure and Functional Testing

Finished valves are subjected to applicable shell pressure and seat leakage tests. Operating function, torque-related conditions, appearance, marking, and other specified inspection items are also checked before release.

7. Final Inspection and Packaging

Final inspection covers product identification, required documents, valve condition, protective covers, accessories, and packaging. Flange faces and other exposed connection surfaces should be protected during transportation to reduce the risk of handling damage.

Typical Applications

Water Treatment and Utility Piping

Used for isolation in water treatment equipment, utility pipelines, pumping systems, and related industrial water applications when the selected materials are compatible with the service medium.

Oil and Gas Systems

Applicable to pipeline isolation and equipment connections in oil and gas systems where the pressure class, material specification, seat configuration, and applicable standards meet the project requirements.

Chemical Processing

Can be specified for compatible chemical process media. Material selection should consider the chemical composition, concentration, temperature, pressure, and potential effects on the body, ball, stem, and seat.

Power and Industrial Process Systems

The flanged connection and Class 300 configuration make this valve suitable for selected industrial process, utility, and power-system piping where bolted pipeline connections and quarter-turn isolation are required.

Selection and Installation Considerations

Selecting the valve should begin with the actual operating conditions rather than the nominal pipe size alone. The following information should be confirmed before ordering:

Medium: Identify the fluid and check its compatibility with the body, ball, stem, seat, packing, and gasket materials.

Pressure and Temperature: Confirm normal and maximum operating pressure, temperature range, pressure fluctuations, and applicable pressure-temperature ratings.

Flange Connection: Match the valve flange size, Class 300 rating, RF facing, bolt-hole arrangement, gasket type, and pipeline flange dimensions.

Flow and Port Configuration: Confirm whether full-port or reduced-port construction is required based on flow capacity, pressure drop, and piping requirements.

Actuator: For automated valves, provide the required operating torque, actuator type, power or air supply, control signal, and feedback requirements.

Installation: Pipeline flanges should be correctly aligned before bolting. The valve should not be forced into position to compensate for pipe misalignment, and the valve should remain within its specified pressure and temperature limits during operation.

Testing and Documentation

Valve inspection can include shell pressure testing, seat leakage testing, dimensional inspection, operating checks, visual inspection, and marking verification according to the applicable order requirements. API 598 is specified for testing and inspection of this valve.

Technical documentation can be provided according to the product configuration and project requirements. Available documents may include product datasheets, dimensional drawings, material information, inspection records, and applicable test documentation.
