Q21Y Pneumatic High-Pressure Ball Valve Overview

The Q21Y Pneumatic High-Pressure Ball Valve is a high-pressure specialized ball valve driven by a pneumatic actuator, designed to meet the requirements of high-pressure working conditions. The valve body is made of forged steel or stainless steel, and features a metal hard-seal or reinforced sealing structure internally. The pneumatic actuator drives the stem to rotate the ball 90 degrees for rapid opening and closing. This valve is specifically designed for high-pressure gases, liquids, and corrosive media, with a working pressure of up to PN160 or higher. It is suitable for applications in petrochemicals, natural gas, high-pressure filling systems, and industrial automation, serving as key equipment for achieving rapid, reliable shut-off and automated control in high-pressure pipelines.

Q21Y Pneumatic High-Pressure Ball Valve Features

1. Reliable High-Pressure Sealing: Utilizes metal hard-seal or reinforced composite sealing structures, offering high-pressure resistance and wear resistance, ensuring reliable sealing and long service life under high-pressure differential conditions.

2. Rapid Response of Pneumatic Actuation: Equipped with single-acting or double-acting pneumatic actuators, enabling fast opening and closing (typically within seconds) with sensitive response, suitable for automated control and emergency shut-off.

3. Compact Structure and High Pressure Resistance: The valve body is made of forged steel or high-strength stainless steel, featuring a compact design and high-pressure-bearing capacity, ideal for high-pressure and high-frequency operation conditions.

4. Comprehensive Safety Protection Design: Typically includes fireproof and anti-static structures, with a stem anti-blowout design. Some models support automatic reset in case of air source failure (single-acting spring return).

5. Intelligent Control and Easy Maintenance: Can be configured with accessories such as solenoid valves and limit switches to achieve remote control and status feedback. The modular design facilitates maintenance and seal replacement.
