Pneumatic Stainless Steel Flanged Ball Valve

The Pneumatic Stainless Steel Flanged Ball Valve is an automated industrial valve designed for pipeline flow control and shut-off. Manufactured by Huadu Valve Group, it uses SS304 / SS316 stainless steel material and is well suited for automatic industrial working conditions.

It is widely used in chemical auxiliary pipelines, water treatment facilities, oil gas processing lines and automated production systems where automatic control, corrosion resistance and operational safety are critical.

The Pneumatic Stainless Steel Flanged Ball Valve ensures stable operation and long service life in demanding industrial environments.

Key Attributes

Raw Material & Structural Advantages

High Quality Stainless Steel Valve Body

The Pneumatic Stainless Steel Flanged Ball Valve is made from genuine SS304 & SS316 stainless steel material, ensuring:

-Superior rust, oxidation and corrosion resistance for humid, salty and mildly corrosive media

-Avoid rust accumulation, scale formation and medium contamination under long term service

-Standard casting & forging technology eliminates internal sand holes and air gap defects

-Solid pressure resistant structure, anti deformation under continuous running & frequent cycling

-Lower unexpected failure risk and reduced end-user replacement cost

Strict Material Inspection

Each batch of raw materials is tested to ensure:

-Accurate chemical composition for SS304 / SS316 grades

-No recycled or substandard materials

-Stable mechanical performance for harsh field conditions

Pneumatic Actuator Drive Benefits

The Pneumatic Stainless Steel Flanged Ball Valve is equipped with premium pneumatic actuator, bringing these core merits:

-Air driven 90-degree on-off action, no manual operation required

-Support solenoid valve, limit switch and PLC connection for remote automatic control

- Suitable for high altitude, enclosed workshop and high risk chemical sites to avoid manual safety hazards

- Sensitive & stable switching performance, adapted to frequent on-off cycles of automated production lines

Standard Flange Connection Benefits

Standard industrial flange connection provides:

-Robust fixing, excellent tightness and strong pressure bearing capacity for heavy duty pipelines

-Easy alignment and assembly with standard pipe flanges during on site installation

-Convenient disassembly, inspection and maintenance in later pipeline overhaul

-Full bore inner design minimizes flow resistance, reduces pressure loss and guarantees smooth medium transmission

- Fully compatible with mainstream international industrial piping standards

Optimized Professional Sealing Structure

Optimized sealing details of this pneumatic flanged ball valve deliver:

-High grade PTFE seat with self lubricating and low friction property, smooth switching without scratching ball core

-Improved sealing effect under rated pressure, compensating minor wear from long time operation

-Anti blowout stem design together with multi layer packing, preventing stem ejection and tiny external leakage

-Polished floating ball core realizes precise fitting with seats for reliable bi-directional tight shut off for liquid and gas

Optional Actuator Safety Modes

Multiple actuator options satisfy different site safety requirements:

- Double acting pneumatic actuator: fast and balanced opening closing for general automatic control

- Spring return pneumatic actuator: automatic reset to full-open / full-close position upon air supply failure, preventing medium overflow and equipment damage for chemical & oil gas lines

- Hard anodized aluminum actuator housing, lightweight, wear resistant for dusty and humid workshop environment

- ISO 5211 standard mounting pad for easy matching with solenoid valves, limit switches and positioners
