Mill Test Report Included with each valve

Shanghai Zhibang Valve Manufacture Co., Ltd., an ISO9001 certified manufacturer established in 2016, proudly presents our Pneumatic Actuated Plunger Valve — a robust solution engineered for automated process pipelines. Combining the reliability of a plunger valve with the precision of a pneumatic actuator, this product delivers consistent performance in demanding industrial applications. Each valve comes with a 1-year warranty and a Mill Test Report, ensuring compliance with quality standards and providing full traceability. Whether you are managing oil, gas, chemical, or water treatment systems, our valve is designed to optimize flow control and reduce maintenance downtime.

Key Features & Technical Specifications

Pneumatic Actuator Options: Double-acting or spring-return (fail-safe) configurations available, compatible with standard 4-20 mA or 0-10 V control signals.
Plunger Valve Design: Straight-through or angle body styles minimize pressure drop and provide self-cleaning action, ideal for viscous or slurry media.
Durable Construction: Body materials in carbon steel, stainless steel (304/316), or special alloys upon request, with hard-faced plunger and seat for extended service life.
Sealing Options: PTFE, reinforced PTFE, or metal-to-metal seals ensure leak-tight shut-off under high pressure and temperature.
Flow Characteristics: Linear or equal percentage for precise control in automated systems.
Accessories: Positioner, solenoid valve, limit switches, filter regulator, and manual override can be integrated as needed.
Testing & Documentation: Every valve is hydrostatically tested and accompanied by a Mill Test Report (MTR) for material verification.

Advantages for Your Automated Process

Reliable Shut-Off: The plunger design ensures positive sealing even with particulates, reducing leakage risk.
Low Maintenance: Simple construction with fewer moving parts results in lower MTBF (Mean Time Between Failures).
Fast Actuation: Pneumatic actuator provides rapid open/close or modulating control, improving system responsiveness.
Full Traceability: Mill Test Report documents material chemistry and mechanical properties, meeting ASTM/EN standards.
Customizable Configuration: Available with various trim materials, coatings, and actuator sizes to match your exact process requirements.
Cost-Effective: Competitive pricing without compromising quality, backed by factory-direct support.

Shanghai Zhibang Valve Manufacture Co., Ltd. has been a trusted manufacturer since 2016, exporting US$1 million to US$1.5 million annually to markets across North America, South America, Europe, Asia, Africa, and Oceania. Our ISO9001-certified production facility in Shanghai, China, ensures rigorous quality control from raw material inspection to final assembly.

Frequently Asked Questions (FAQ)

What is the difference between a plunger valve and a globe valve?
Plunger valves use a cylindrical plunger that moves linearly within a seat, providing a self-cleaning action and tight shut-off even with dirty fluids. Globe valves have a disc that moves perpendicular to the seat, which can be more prone to wear in abrasive media.
Can this valve be used for on/off control, or only for modulating?
It can be used for both. With a double-acting actuator, it works as an on/off valve. With a positioner and spring-return actuator, it can perform modulating control with high accuracy.
What is the standard delivery time for this product?
Standard lead time is 2–4 weeks, depending on quantity and customization. Urgent orders can be accommodated with expedited production.
Do you provide the Mill Test Report for all materials?
Yes, a Mill Test Report (MTR) is included with every valve, documenting the chemical composition and mechanical properties of the body and trim materials.
What actuation supply pressure is required?
Standard pneumatic actuators require 4–8 bar (60–120 psi) clean, dry air. For higher pressure ratings, we can supply actuators with appropriate sizing.
Is the valve suitable for high-temperature applications?
Standard temperature range is -20°C to +200°C. For higher temperatures up to 500°C, we offer optional metal seats and special materials — please consult our engineering team.
Can I get a sample valve for testing before bulk order?
Yes, sample orders are welcome. We typically require 100% payment for samples, with the cost deducted from future bulk orders.
What certifications does your company hold?
Our manufacturing facility is ISO9001 certified. We can also provide CE, ATEX, or other certifications upon request (subject to feasibility and additional cost).
