Product Introduction
Product Overview
The Double-Acting Plastic Pneumatic Ball Valve is a high-performance, lightweight, and corrosion-resistant flow control solution designed for automated industrial systems. Combining a durable plastic valve body with a pneumatic actuator, it ensures fast, reliable, and energy-efficient operation in liquid and gas applications.
This valve is ideal for chemical processing, water treatment, irrigation, and industrial automation, where resistance to corrosive media and remote control are essential.
Key Features
Robust Plastic Construction - Valve body made from PP (Polypropylene), PVDF, or CPVC, offering excellent chemical resistance and lightweight durability.
Pneumatic Double-Acting Actuator - Uses compressed air (4-7 bar / 60-100 psi) to rotate the ball 90° for quick ON/OFF control. Auto-returns to position upon air signal reversal (no spring required).
Bubble-Tight Sealing - PTFE or EPDM seats ensure zero leakage, even under pressure.
Compact & Lightweight - Easier to install and maintain compared to metal valves, reducing system load.
Corrosion & Chemical Resistance - Perfect for acids, alkalis, solvents, and aggressive fluids(material selection depends on media).
Multiple Port Options - 2-way (2/2) or 3-way (3/2) configurations available for diverse piping needs.
Manual Override Option - Some models include a hand lever for emergency operation in case of air supply failure.
