Shanghai Zhibang Valve Manufacture Co., Ltd. has been a trusted manufacturer of high-performance industrial valves since 2016. Our Flanged Plunger Valve is specifically engineered for the demanding conditions of power plant boiler feed water pipelines, where high pressure and reliability are non-negotiable. Built with precision and durability, this valve ensures leak-tight sealing and smooth operation, even under extreme thermal and mechanical stress. Discover how our advanced design can optimize your water treatment system and reduce maintenance downtime.
Key Features & Technical Specifications
- High-Pressure Capability: Designed to handle pressures up to 2500 psi (Class 2500), making it suitable for boiler feed water applications with severe operating conditions.
- Flanged Connection: Standard raised-face (RF) or ring-type joint (RTJ) flanges ensure easy installation and reliable sealing in piping systems.
- Plunger Design: The unique plunger mechanism provides a straight-through flow path with minimal pressure drop, while the sealing surface is self-cleaning and resistant to erosion.
- Material Options: Available in carbon steel (A216 WCB) or stainless steel (A351 CF8M) with hard-facing on critical sealing surfaces for extended service life.
- Temperature Range: Operates efficiently from -29°C to 425°C, with optional high-temperature packing for elevated steam applications.
- Leak-Tight Sealing: Metal-to-metal seating with optional soft seal inserts ensures zero leakage in both directions, meeting stringent API 598 requirements.
- Low Maintenance: The plunger and seat can be easily replaced without removing the valve from the pipeline, reducing downtime and labor costs.

Advantages for Your Boiler Feed Water System
- Enhanced Reliability: The plunger design eliminates the common problems of wedge gate valves, such as seat galling and sticking, ensuring consistent performance over thousands of cycles.
- Energy Savings: Low torque operation reduces actuator size and energy consumption, contributing to lower total cost of ownership.
- Versatility: Suitable for both isolation and regulation services in boiler feed water, blowdown, and other high-pressure water applications.
- Corrosion Resistance: Optional stainless steel or hard-coated internals withstand aggressive water chemistry and prevent scaling.
- Global Compliance: Designed to meet international standards, making it acceptable for projects in North America, Europe, Asia, and beyond.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum working pressure for this plunger valve?
A: The valve is available in pressure ratings from Class 150 to Class 2500. For specific pressure requirements, please consult our engineering team. We can customize the design to meet your exact needs. -
Q: Can this valve be used for high-temperature boiler feed water?
A: Yes, the standard design handles temperatures up to 425°C. For higher temperatures, we offer optional high-temperature packing and materials like stainless steel with Stellite overlay. -
Q: What materials are available for the valve body?
A: The most common body materials are carbon steel (A216 WCB) and stainless steel (A351 CF8/CF8M). Other materials such as alloy steel or duplex stainless steel are available upon request. -
Q: How does the plunger design differ from a gate valve?
A: The plunger valve uses a cylindrical plunger that moves linearly to open or close the flow path. This design provides a straight-through flow, reduced turbulence, and self-cleaning action, minimizing wear and leakage compared to traditional gate valves. -
Q: Is the valve suitable for both on/off and throttling applications?
A: Yes, the plunger valve can be used for isolation (on/off) and moderate throttling. For precise flow control, we recommend an actuator with positioner. -
Q: Do you provide certificates of material or pressure tests?
A: Absolutely. We can supply material certificates (EN 10204 3.1/3.2), pressure test reports, and other documentation as required. Our ISO9001 quality system ensures traceability. -
Q: What is the typical lead time for this valve?
A: Lead time depends on size, material, and quantity. Standard sizes in carbon steel are typically 15–30 days. Custom orders may require 30–45 days. We work closely with logistics to ensure timely delivery from our ports. -
Q: Can I get a sample before placing a bulk order?
A: Yes, sample orders are welcome. We offer competitive pricing for samples, and the cost can be deducted from future bulk orders. Please contact our sales team for details.
