Shanghai Zhibang Valve Manufacture Co., Ltd is proud to introduce our Alloy Steel Plunger Valve, engineered for the most demanding natural gas high-pressure applications. Rated at 2500LB ANSI and available in bore sizes from 2" to 12", this valve meets the rigorous API 6D standard and features a full welded body design for maximum integrity and leak prevention. As a manufacturer with ISO9001 certification and over US$1 million annual export value, we guarantee reliable performance and long service life in critical gas transmission systems.
Our plunger valve is specifically designed to handle high-pressure natural gas environments where safety and durability are non-negotiable. The full welded construction eliminates potential leak paths, while the alloy steel material provides excellent resistance to corrosion and erosion caused by gas impurities. Whether you need a valve for on/off control or throttling service, this product delivers consistent operation with minimal maintenance.
Below we detail the key features, technical specifications, and benefits that make this valve a preferred choice for pipeline operators and gas processing plants worldwide.
Key Features & Benefits
- Full Welded Body: Eliminates flange joints, reduces weight, and prevents external leakage even under extreme pressure fluctuations.
- Alloy Steel Construction: High tensile strength and excellent low-temperature impact toughness, suitable for natural gas applications in harsh climates.
- 2500LB ANSI Pressure Rating: Designed for high-pressure systems up to 4250 psi (depending on temperature), ensuring safe operation under severe conditions.
- API 6D Compliance: Meets the international standard for pipeline valves, including shell test, seat leakage test, and fire-safe design.
- 2"-12" Bore Range: Flexible sizing to fit various pipeline diameters, with custom sizes available upon request.
- Low Torque Operation: Optimized plunger and seat design reduces operating torque, allowing easy manual or actuator control.
- Bi-Directional Sealing: Provides reliable shut-off in both flow directions, with optional DBB (Double Block & Bleed) capability.
- Fire-Safe Design: Optional API 607 fire test certification can be added for enhanced safety in critical applications.

Detailed Product Description
The Alloy Steel Plunger Valve incorporates a unique plunger design that provides a tight seal against the seat, making it ideal for natural gas high-pressure applications where zero leakage is critical. The full welded body is manufactured using advanced welding techniques and undergoes 100% radiographic inspection to ensure weld integrity. This construction not only reduces the overall weight of the valve compared to flanged designs but also eliminates potential leak paths, enhancing reliability in remote or hazardous locations.
Our valve meets the API 6D specification, which covers design, manufacturing, testing, and documentation for pipeline valves. It is also designed to comply with ASME B16.34 for pressure-temperature ratings. The 2500LB pressure class allows the valve to operate safely in systems with working pressures up to 4250 psi (at 100°F), making it suitable for high-pressure gas transmission lines, compressor stations, and gas storage facilities.
Customer Benefits:
- Reduced Maintenance: The full welded design and self-lubricating seal materials minimize wear and extend service intervals.
- Enhanced Safety: Fire-safe design (optional) and anti-static device prevent ignition in explosive gas environments.
- Cost Efficiency: Lighter weight reduces installation costs, while the long service life lowers total cost of ownership.
- Versatility: Compatible with manual, gear, or actuator operation, and can be customized for sour gas (NACE MR0175) service.
We also offer optional features such as:
- Internal and external coatings for corrosion protection
- Extended stem for buried service
- Position indicator and locking device
- Bleed valve and drain connection

Frequently Asked Questions
-
Q: What is the difference between a plunger valve and a ball valve?
A: A plunger valve uses a cylindrical plunger that moves linearly to seal against a seat, while a ball valve uses a rotating ball. Plunger valves typically offer better throttling capability and tighter shut-off in high-pressure gas services. -
Q: Can this valve be used in sour gas (H2S) service?
A: Yes, we can supply the valve with NACE MR0175 compliant materials (e.g., Inconel trim, special heat treatment) upon request. Please specify your requirement when ordering. -
Q: What is the maximum operating temperature for this valve?
A: Standard temperature range is -29°C to +200°C. For higher temperature applications, we can use alternative seal materials like PEEK or metal seals, extending the range to +400°C. -
Q: Is the valve fire-safe?
A: The standard design can be upgraded to meet API 607 fire test requirements. Please indicate if fire-safe certification is needed. -
Q: What end connections are available?
A: We offer butt weld, raised face flanged (ASME B16.5), ring joint (RTJ), and custom connections. The default for 2500LB is typically RTJ or butt weld. -
Q: How long is the delivery time?
A: For standard sizes (2"-12"), delivery is typically 30-45 days after order confirmation. Custom or rush orders can be arranged with prior discussion. -
Q: Do you provide a warranty?
A: Yes, we provide a 12-month warranty against manufacturing defects. Extended warranty options are available. -
Q: Can I get a sample valve for testing?
A: We can provide a sample for qualified buyers. Please contact our sales team for terms.
