Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a professional manufacturer dedicated to providing high-quality valve solutions for the oil and gas industry. Our Alloy Steel Plunger Valve for Natural Gas Pipeline is specifically engineered to withstand extreme pressures up to 3000 PSI, making it an ideal choice for long-distance transmission systems. With over US$1 million in annual export value and a global presence across North America, South America, Europe, and Asia, we have earned the trust of international clients through reliable performance and rigorous quality control.
This plunger valve is designed to deliver precise flow control and bubble-tight shut-off in demanding natural gas applications. Its robust alloy steel construction ensures durability and resistance to corrosion, while the plunger mechanism provides smooth operation even under high differential pressure. Whether used in mainline pipelines, distribution networks, or gathering stations, our valve offers exceptional reliability and minimal maintenance requirements.

Product Advantages for Long-Distance Natural Gas Transmission
- High-Pressure Integrity: Designed to safely handle 3000 PSI operating pressure, ensuring reliable performance in mainline transmission systems.
- Leak-Proof Sealing: The plunger design provides a metal-to-metal seal with optional soft inserts, achieving bubble-tight shut-off even under high differential pressure.
- Corrosion Resistance: Alloy steel body with optional stainless steel trim resists sour gas (NACE MR0175 compliant upon request) and harsh environmental conditions.
- Low Maintenance: Fewer moving parts compared to gate or ball valves, reducing maintenance frequency and operational downtime.
- Long Service Life: Hardened wear surfaces and robust construction extend the valve's lifespan, even under frequent cycling or throttling service.
- Customizable Configurations: Available in different sizes, connections, and trim materials to meet specific pipeline requirements.

-
Q: What is the maximum operating pressure for this plunger valve?
A: The standard pressure rating is 3000 PSI, but we can design higher pressure ratings (up to 6000 PSI) upon request. -
Q: Can this valve be used for sour gas (H2S) service?
A: Yes, we can provide NACE MR0175 compliant trim materials (e.g., Inconel 718, 316L) to resist sulfide stress cracking. -
Q: What connection types are available?
A: Flanged (RF, RTJ) and threaded connections are standard. We can also offer butt weld ends or other custom connections. -
Q: How long is the delivery time?
A: Typical lead time is 30–45 days for standard sizes, depending on quantity and customization. Urgent orders can be expedited. -
Q: Do you provide testing certificates?
A: Yes, we provide material certificates, pressure test reports, and a certificate of conformity. Third-party inspection (e.g., SGS, BV) is also available. -
Q: Is this valve suitable for manual or automated operation?
A: Both. We offer handwheel, gearbox, pneumatic actuator, and electric actuator options. The valve body is designed to accept standard actuator mounting (ISO 5211). -
