High Pressure﹠Sulfur Corrosion Resistance: Features high-pressure rated body and SSC-resistant materials, suitable for high-ΔP and H₂S-containing services

Emergency Pressure Relief: Automatically vents the valve body cavity during abnormal pressure buildup to improve system safety

Intelligent Control﹠Remote Monitoring：Supports HART, Profibus DP, Modbus protocols; integrates with DCS/PLC systems for remote monitoring and fault diagnostics.

Core Product Features

Pneumatic Oxygen Control Valves | Bellows Seal Valves | High-Pressure Angle Control Valves | Corrosion-Resistant Butterfly Valves

Key Applications & Case Studies

Oxygen Control for Coal-to-Chemicals (CTC) Gasification Units

Control and Isolation of Highly Corrosive Media (e.g., Acetic Acid, Sulfuric Acid) in Polyvinyl Alcohol (PVA) and Purified Terephthalic Acid (PTA) Processes

High-Pressure Differential Control for Urea Systems

Hazardous Gas Management (O₂/Cl₂)

Core Features & Technical Advantages

Corrosion/Erosion Resistance: Offers austenitic stainless steel, Hastelloy, titanium and other special metals with surface treatments. Valve trim commonly uses Stellite alloy hardfacing (≥HRC 55-60) to enhance hardness and wear resistance.

High-Sealing Integrity: Utilizes PTFE-graphite composite packing and bellows seal structures to ensure zero leakage of highly toxic and hazardous media.

High Pressure Drop﹠Anti-Cavitation Design: Multi-stage throttling (e.g., in high-pressure angle valves) effectively distributes pressure drop, reducing cavitation and erosion to extend service life.

Degreasing Treatment: Valves for oxygen and other special media undergo degreasing to ensure safety.
