DK07 Pilot Operated Stainless Steel Diaphragm Solenoid Valve (Corrosion Resistant)
The DK07 is a robust Pilot Operated Diaphragm Solenoid Valve built with high-grade Stainless Steel (SS304/SS316), making it ideal for mainline industrial control in challenging environments. It effectively combines the high flow capacity and energy efficiency of pilot operation with the superior chemical resistance of stainless steel. This makes the DN07 the definitive solution for reliable on/off control of mildly corrosive liquids, steam, pure water, and gases in systems that maintain a minimum pressure differential.
Size Range: DN15-DN50
Pressure Range: 0.3-16 Bar
Thread Standard: G / BSPP / NPT
Voltage: AC/DC 12V/24V110V/220V
Features
Combining durable stainless steel construction for chemical resistance with a pilot-operated mechanism for high flow, the DN07 provides efficient and reliable fluid control in corrosive industrial environments with stable line pressure.
✅Superior SS304/SS316 Construction: Precision-cast stainless steel body offers excellent resistance to rust, oxidation, steam, and mildly corrosive liquids, ensuring long service life in demanding media applications.
✅Pilot Operation for High Flow: Utilizes system pressure to assist actuation, enabling significantly larger orifice sizes and higher flow capacity (CV) than direct-acting valves of similar dimensions.
✅Minimum Pressure Differential Required: Designed to function optimally in systems that maintain a stable minimum pressure differential (typically 0.05 MPa / 7 PSI), suitable for mainline flow control.
✅Wide Media Versatility: Ideal for handling high-temperature media like steam (with PTFE/Viton seals) and clean media like deionized water or purified gases, where metal contamination is a concern.
✅Energy-Efficient Design: The pressure-assisted pilot mechanism requires lower electrical power than large direct-acting coils, making it highly suitable for applications requiring long continuous operating cycles.
