DELCO YK43X/F Pilot Operated Piston Pressure Reducing Valve, Gas / Steam, Flanged
Designed for high-capacity industrial applications, the YK43X/F Series is a pilot-operated piston pressure reducing valve that provides superior stability and flow control for gases and steam. Its robust piston mechanism ensures precise downstream pressure regulation even under fluctuating inlet conditions, making it the preferred choice for large-scale air separation plants and steam headers.
Size Range: DN15-DN500
Material: WCB, Stainless Steel etc.
Flange Standard: GB / ANSI /DIN /JIS etc.
Features
A heavy-duty pilot piston pressure regulator delivering high flow rates and precise outlet pressure stability for demanding gas and steam pipelines.
✅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).
