Shanghai Zhibang Valve Manufacture Co., Ltd, a professional manufacturer founded in 2016, presents our Carbon Steel Plunger Valve with Custom Bore Size, Threaded Connection, 6000 PSI Rated. This high-performance valve is designed to meet the demanding requirements of industrial fluid control systems, offering exceptional reliability and precision. With a robust carbon steel body and customizable bore diameter, it provides a tailored solution for applications ranging from oil and gas to chemical processing. Our commitment to quality is backed by ISO9001 certification and a proven track record of exporting to over 15 countries worldwide.
The plunger valve operates by a linear motion of a cylindrical plunger that opens or closes the flow passage, delivering precise throttling and shut-off capabilities. Unlike traditional gate or globe valves, the plunger design minimizes turbulence and pressure drop, making it ideal for high-pressure systems up to 6000 PSI. The threaded connection ensures a secure, leak-proof installation, while the custom bore size allows you to optimize the flow characteristics for your specific process. Whether you need a small bore for metering or a larger bore for high flow, we can accommodate your requirements.

Key Features & Benefits
- High-Pressure Capability: Rated at 6000 PSI, suitable for extreme hydraulic and pneumatic systems, ensuring safe operation under high stress.
- Custom Bore Size: Choose the exact bore diameter to match your flow requirements – from fine metering to full flow – without compromising system performance.
- Threaded Connections: Easy to install and maintain, compatible with standard pipe threads (NPT, BSPT) and available in custom thread configurations.
- Durable Construction: Carbon steel body resists corrosion and wear, with optional surface treatments (e.g., zinc plating, epoxy coating) for extended service life.
- Precise Flow Control: The plunger design provides linear flow characteristics, enabling accurate throttling and repeatable shut-off.
- Low Maintenance: Simple internal structure with replaceable seals reduces downtime and repair costs.
- Versatile Applications: Ideal for oil & gas, chemical processing, water treatment, power generation, and industrial machinery.
- ISO9001 Quality Management: Manufactured under strict quality control procedures, ensuring consistent performance and reliability.
Customization Options
We understand that every system has unique requirements. Our Carbon Steel Plunger Valve can be tailored in several ways:
- Bore size: from 1/8" to 3" or larger, depending on application.
- Thread type: NPT, BSPT, BSPP, metric, or custom threads.
- Seal material: PTFE for chemical resistance, NBR for oil, Viton for high temperature, or others.
- Stem length and handle type: handwheel, lever, or locking mechanism.
- End connections: threaded, flanged, or welded (upon request).
- Surface finish: standard mill finish, or coated for corrosion protection.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum bore size available for this plunger valve?
A: The standard custom range starts from 1/4 inch (6.35 mm) inner diameter. Smaller bores (down to 1/8 inch) are possible depending on the application. Please contact our sales team with your specific requirements. -
Q: Can the valve be used for steam service at 6000 PSI?
A: The valve is designed for high-pressure steam, but the temperature limit of the standard seal materials (e.g., PTFE up to 260°C) must be considered. For high-temperature steam, we recommend Viton or metal seals, which are available upon request. -
Q: What thread standards are compatible with this valve?
A: We offer NPT (American), BSPT (British), and BSPP threads as standard options. Custom threads such as metric or JIS can be machined to order. Please specify the thread type when placing your order. -
Q: Is the valve suitable for corrosive chemicals?
A: The carbon steel body provides good resistance to mild chemicals, but for aggressive media (acids, caustics), we recommend upgrading to stainless steel or lining the valve. We can also provide special seal materials like PTFE or FKM for chemical compatibility. -
Q: Do you offer samples for testing before bulk purchase?
A: Yes, we provide samples with a lead time of 7-15 working days. Sample costs are negotiable, and we can deduct the sample fee from your first bulk order. Please contact us to discuss your testing requirements. -
Q: What is the typical delivery time for a custom bore valve?
A: Standard custom orders usually take 15-25 working days after design confirmation. For urgent projects, we can expedite production to 10-15 working days for an additional fee. Shipping from Shanghai port takes 5-30 days depending on the destination. -
Q: How do you ensure the valve meets the 6000 PSI rating?
A: Each valve is hydrostatically tested at 1.5 times the rated pressure (9000 PSI) and pneumatically tested at 6000 PSI. We also provide a test certificate upon request. Our ISO9001 quality system ensures traceability and consistency. -
Q: Can I get a custom handle or actuator for this valve?
A: Yes, we offer handwheel, lever, and locking handle options. For automated control, we can integrate pneumatic or electric actuators. Please provide your specifications so we can recommend the suitable solution.
Conclusion: Our Carbon Steel Plunger Valve with Custom Bore Size, Threaded Connection, and 6000 PSI rating is a reliable, customizable solution for demanding industrial applications. With Shanghai Zhibang Valve's expertise, ISO9001 certification, and global shipping capabilities, you can trust us to deliver high-quality valves that meet your exact needs.
