3PC Heavy Duty Ball Valve with Locking Device

Shangtai 3PC Heavy Duty Ball Valve with Locking Device is designed for industrial pipeline systems requiring secure shut-off and controlled manual operation. The three-piece construction provides access to internal components for maintenance, while the lockable handle helps prevent unintended valve operation. Different seat, seal, pressure, and temperature configurations can be provided according to the working medium and application requirements.

Advantages

1. Heavy-Duty Three-Piece Construction

The reinforced three-piece body is designed for industrial pipeline service where a robust valve construction is required. The three-piece design also allows the valve to be opened for inspection or maintenance without removing the entire valve body from the pipeline.

2. Lockable Handle for Controlled Operation

The integrated locking device helps keep the handle in the selected valve position and reduces the risk of accidental or unauthorized operation. This feature is useful in industrial systems where valve position needs to be controlled during operation or maintenance.

3. Anti-Blowout Stem Design

The stem is internally retained to help prevent stem ejection when the valve is under pressure. This construction provides an additional safety feature for industrial on/off service.

4. Stainless Steel Material Options

The standard material configuration includes SS316 and SS304 options for the body, ball, stem, and other components. PTFE is used for the ball seat, friction ring, and stem packing in the listed configuration. Material selection should be matched to the working medium, pressure, and temperature.

5. Pressure and Temperature Capability

The valve is specified with a CL150 pressure class, a maximum pressure of 540 PSI, and a temperature range of -25℃ to 150℃ according to the listed configuration. The actual allowable working pressure should be checked against the applicable pressure-temperature conditions before selection.

6. Factory Manufacturing and Quality Control

Shangtai manages valve production, machining, assembly, inspection, and pressure testing at its factory. Material documentation and applicable CE and ISO 9001 certificates can be provided according to product and order requirements.

FAQ

1. What is a 3PC Heavy Duty Ball Valve with Locking Device?

It is a three-piece ball valve designed for industrial on/off service and equipped with a locking device on the handle. The three-piece construction allows access to the internal valve components for inspection and maintenance.

2. What is the purpose of the locking device?

The locking device helps secure the handle in the selected open or closed position and reduces the possibility of unintended valve operation during normal service or maintenance.

3. What pressure and temperature can this valve handle?

The listed configuration has a CL150 pressure class, a maximum pressure of 540 PSI, and a temperature range of -25℃ to 150℃. The actual allowable pressure should be confirmed according to the valve size, temperature, medium, and applicable pressure-temperature rating.

4. What materials are available?

The listed configuration uses SS316 and SS304 components, with PTFE used for the ball seat, friction ring, and stem packing. Other material options may be available depending on the operating medium and application requirements.

5. What connection standards are available?

The valve is available with NPT and BSP threaded ends. NPT thread ends follow ANSI B 2.1 NPT, while BSP thread ends follow BS21 BSP according to the supplied specification.

6. What is the Kv value of a ball valve?

Kv indicates the flow rate of water in cubic meters per hour that produces a pressure drop of 1 bar across the valve. The listed Kv values can be used as a reference when evaluating flow capacity for different valve sizes.

7. Can the valve be customized for different applications?

Yes. Shangtai can discuss different body, seat, seal, pressure, temperature, connection, and material configurations according to the working medium and application requirements. Other materials are available upon request.

8. What standards are used for the valve?

The supplied specification references ASME B16.34 for design and manufacturing and pressure-temperature ratings, while API 598 is used for testing and inspection. The applicable standard should be confirmed for the specific valve configuration and order.

9. Can material and quality documents be provided?

Yes. Material documentation and applicable CE and ISO 9001 certificates can be provided according to the product configuration and order requirements.

10. Is Shangtai a manufacturer?

Yes. Shangtai manufactures the valve and manages production, machining, assembly, inspection, and related supply processes at its factory in Wenzhou, China.
