DK09 Series Pilot Piston Stainless Steel Solenoid Valve for High-Pressure Steam and Aggressive Media
DELCO's DK09 Series is a robust Pilot Piston Solenoid Valve designed for high pressure and high flow applications. Constructed from durable stainless steel, it is compatible with demanding media like steam, hot water, and corrosive fluids. The pilot-operated mechanism ensures reliable operation with minimal moving parts, making it an excellent choice for industrial process automation.
Features
High-Pressure Tolerance and Superior Corrosion Resistance
✅ Pilot Piston Mechanism (High Flow Capacity): This pilot-operated design utilizes the system pressure to assist in opening and closing the valve, resulting in a larger flow rate (Kv value) and the ability to handle significantly higher pressures compared to direct-acting valves.
✅ Premium Stainless Steel Construction: The valve body is constructed from high-grade stainless steel (e.g., SS304 or SS316), offering superior resistance to corrosion, rust, and high temperatures, making it ideal for use with aggressive or chemically demanding fluids.
✅ Robust High-Pressure Operation: Engineered specifically for demanding environments, the DK09 series is capable of withstanding very high nominal pressures (e.g., up to PN40 / ANSI Class 300), ensuring stable and reliable control in heavy industrial systems.
✅ Wide Temperature Compatibility: Equipped with high-performance sealing materials (such as PTFE or FKM/VITON), the valve is designed to manage a broad range of fluid temperatures, making it highly effective for controlling steam and hot water in boiler systems.
✅ Easy Maintenance Design: The valve features a modular and simplified internal structure, which allows for quick disassembly and servicing of the piston and seals without removing the main valve body from the pipeline, minimizing system downtime.
