ZJHM Piston Double-Acting Pneumatic Control Valve | Two-Way Globe Valve for Precise Flow & Pressure Regulation

✅ High-Precision Control Performance：Equipped with a pneumatic piston actuator and valve positioner supporting 4–20mA or HART signals, the valve delivers fast, accurate response for process automation systems.

✅ Flexible Design Options: Available in straight-through or angle body structures, with cone, needle, or V-shaped port configurations to suit different flow characteristics and industrial requirements.

✅ Durable Material Construction: Made from premium cast steel, stainless steel, or alloy steel (WCB, CF8M), with Stellite alloy overlay on sealing surfaces for excellent wear and corrosion resistance.

✅ Reliable Sealing and Low Leakage: Offers both metal hard seal for high-temperature/high-pressure conditions and soft seal (PTFE/graphite) for chemical compatibility, meeting ANSI Class IV leakage standards.

✅ Wide Industrial Applications: Ideal for use in chemical, petrochemical, power, and HVAC systems where accurate flow and pressure regulation are essential to ensure stable operation and efficiency.
