Description
The Vickers Solenoid Valve KHDG4V-3-02-157451-21 is a high-performance hydraulic control component designed with a combination of direct acting and pilot-operated mechanisms. This allows the valve to perform effectively even in systems with zero pressure difference, using electromagnetic force to operate both pilot and main valves sequentially. When energized, the coil lifts the pilot valve and reduces pressure in the upper chamber, allowing the main valve to open. Upon de-energizing, it uses spring or medium pressure to close the valve securely. The solenoid valve consists of electromagnetic coil, fixed and moving iron cores, and a sealed valve body with internal sliding elements. It supports two-position, multi-way configurations like three-way and five-way options, ensuring versatility in operation modes. Known for low noise, small vibration, and minimal leakage, the valve’s stainless steel components are sprayed with hard alloy, enhancing resistance to erosion and wear. The advanced cage-type valve core, combined with a guide sleeve and smooth operation mechanics, ensures extended service life, high reliability, and efficient fluid regulation across a variety of industrial environments. With precise regulation, this valve is ideal for a wide range of industrial applications including:
• Condensate and steam system regulation
• Water level and pressure control
• Boiler systems, deaerator heating
• Low-pressure heating and drain systems
• Chemical make-up water systems
• Accident drain and auxiliary systems.
Please note that the 'Eaton Vickers' range of hydraulic valves and components is now offered under the 'Vickers by Danfoss' brand continuing the legacy of Vickers one of the most experienced and respected names in hydraulics, which became part of Danfoss in 2021. While the branding has changed, the product design, quality, performance, and model codes remain exactly the same. Customers can expect the same trusted technology and specifications—only now backed by Danfoss, a global leader in engineering solutions.
