DELCO YK43X/F Pilot Operated Piston Pressure Reducing Valve, Gas / Steam, Flanged

✅High-Capacity Piston Design: Utilizes a balanced piston assembly driven by a sensitive pilot valve, enabling the regulator to handle significantly higher flow rates compared to direct-acting diaphragm valves without sacrificing accuracy.

✅Exceptional Pressure Stability: Maintains outlet pressure within a tight tolerance (typically ±5%) regardless of variations in upstream supply pressure or downstream demand, ensuring consistent process conditions.

✅Broad Application Range: Suitable for a wide variety of media including Steam, Compressed Air, Nitrogen, and Oxygen, with specific material options (Stainless Steel or WCB) and seal compatibility available for each service.

✅Durable & Reliable: Constructed with a hardened stainless steel piston and cylinder liner to resist wear and galling, ensuring a long service life even in high-cycle or high-velocity applications.

✅Adjustable Pressure Settings: Equipped with a precise adjustment screw on the pilot valve, allowing operators to easily set and lock the desired downstream pressure across a wide range (e.g., 0.1–2.5 MPa).
