Compact Pneumatic Globe Valve Series


Key Features & Benefits


Superior Cutting Performance

The sharp knife gate design efficiently cuts through viscous media, slurries, and fluids containing solid particles, preventing clogging and ensuring smooth flow.

Wide Pressure & DN Range

Covers pressure ratings of 0.6 - 1.0MPa and DN 50 - 1200, adapting to large-scale industrial pipelines and diverse pressure requirements.

Durable Construction

High-strength materials for valve body and components ensure resistance to wear, impact, and corrosion, extending service life in heavy-duty applications.

Reliable Sealing & Leakage Prevention

Precision-engineered gate and seat ensure tight sealing, even with abrasive media, minimizing leakage and reducing operational risks.

Easy Installation & Compatibility

Flange connection complies with industrial standards, enabling seamless integration with existing pipelines. Compact design saves installation space.

Low Operational Resistance

Unobstructed flow path when fully open reduces pressure loss, improving system energy efficiency and reducing operating costs.


Applications & Suitable Industries


Ideal for handling slurry, tailings, and mineral-laden fluids in mining operations and concentrators.

Used in pulp pipelines, wastewater treatment, and paper production processes to control fibrous and viscous media.

Suitable for municipal and industrial wastewater systems, handling sewage, sludge, and solid-containing effluents.

Regulates and shuts off corrosive slurries, chemical mixtures, and waste streams in chemical plants and refineries.

Controls cement slurry, aggregate mixtures, and other viscous materials in concrete production and construction sites
