Solenoid valve valve 6240 The compact power Gases, drinking water, hot liquids and steam are the application focuses of the type 6240 piston valve. The body, seals and design were selected in accordance with the required certificates and general requirements. The piston solenoid valve 6240 combines the advantages of a servo-controlled and a direct-acting valve. It is suitable for both high pressures and large diameters. The fixed coupling between the pilot valve and piston of the main seat ensures complete opening even without differential pressure. The advanced piston design and optimal...

The material and construction form the basis for a valve’s reliability and safe operation. Especially fuel gases and steam place high requirements on the materials used. The 2/2-way piston valve type 6240 features a large selection of tested materials. This makes it possible to adapt the valve to specific applications. The following versions are available: Versions optimized for applications are also available, in addition to certifications, facilitating the choice of the right valve. The following table provides an overview. Pressure range: 0 to 25 bar for liquids (up to 40 bar for gaseous...

Functioning principle Sample applications Spring-coupled piston valve Steam applications The anchor of the pilot valve is firmly connected by a spring to the piston of the main valve. The springcoupling ensures that a force is exerted directly on the piston when the valve is switched on, causing the main valve to open. Even without differential pressure this force is sufficient to open the valve completely­ . At a high differential pressure the switching of the valve is determined essentially by the characteristics of the servo valve. In this case the differential pressure supports the...

Fluidic design and robust construction Highly durable and resistant Effective explosion protection Compact and highly efficient Body variants and pressure ranges Explosion protection Compact power bundle The brass version of the valve is suitable for controlling liquids and gases. The special fluidic form (ramp design) of the valve body enables maximum flow rates. The stainless steel version allows use in slightly acidic and alkaline solutions. For applications in gases the device is available with PTFE sliding rings, which ensure low-wear operation and long maintenance intervals even when...
