DK07 Pilot Operated Brass Diaphragm Solenoid Valve (High Flow Capacity)

The DK07 is a heavy-duty Pilot Operated Diaphragm Solenoid Valve designed for large industrial lines requiring high flow rates and robust pressure handling. Unlike direct-acting valves, the DK07 utilizes system pressure (minimum differential required) to assist in opening and sealing, allowing for a compact yet powerful coil that is energy-efficient. Constructed from durable forged brass, it is an ideal, cost-effective solution for controlling neutral fluids like water, air, and inert gases in mainline industrial and irrigation systems.

Features

Built with durable brass for longevity, the DK07 is a pilot-operated diaphragm valve engineered for high flow rates and efficient control in mainline industrial systems where a stable minimum pressure differential is present.

✅Pilot-Operated (Indirect Acting): Utilizes line pressure to amplify the sealing force and open the valve, enabling high flow rates and larger port sizes than direct-acting valves with the same coil power.

✅High-Pressure & High-Flow Handling: Designed to manage standard industrial line pressures (e.g., 0.5~10 bar) and accommodate larger flow coefficients (CV) suitable for mainline fluid control applications.

✅Energy Efficient Coil: Due to the pressure-assisted operation, the coil requires less electrical power for actuation than a direct-acting valve of comparable flow capacity.

✅Durable Forged Brass Body: Constructed from high-quality brass, providing excellent resistance to water, oil, and inert gases, ensuring long-term reliability in general-purpose industrial environments.

✅Wide Pressure Operating Range: Optimized for systems that maintain a stable minimum pressure differential (e.g., typically 0.05MPa or 7PSI), ensuring reliable opening and closing cycles.
