The German vatten VA series of pneumatic actuators is of compact design, long life, high quality, worm gear type pneumatic actuator. The product is used for the 90 °rotary valve, ball valve, butterfly valve, such as gate valve. The use of Germanys most advanced production technology and process technology in the quality and performance of products has made the VATTEN unique, distinctive considerable value.
Indicator
Each standard products are provided with a butterfly type switch indicator
Output shaft
Nickel alloy steel, high precision integrated
The output shaft at the same time with NAMUR, ISO5211, DIN3337 standards.
Cylinder block
Cylinder block material for aluminum alloy, internal and external surface after anodic oxidation and polished to 45-50u. At the same time the external after nickel plating treatment, the pneumatic actuator anticorrosion performance is improved greatly. Diameter of cylinder piston friction antiwear treatment after guaranteed minimum value.
End cover
Aluminum die casting, epoxy resin heat treatment, corrosion resistance!
Piston
Aluminum alloy die casting and heavy, with a high-quality seals, enables the actuator in a certain input pressure maximum output torque. Symmetric mounting position, fast operation, long service life, simple inverted piston can change the direction of rotation.
Stroke adjustment
By two bolts to + -5 °trimming and in 0° and 90 °two fine-tuning, fine-tuning is called double insurance.
Heavy load spring
Germany imported spring VATTEN composite high strength spring high strength alloy steel production to ensure stable performance, long life.
Seal up
Using NBR-70 rubber sealing ring, securing the actuator at normal operating temperature reliability. If the special environmental needs of low and high temperature can be fluorine rubber sealing ring of the trait
VA104 series pneumatic powder butterfly valve is by Shanghai Fadden valve limited company introduction of foreign advanced technology development, which consists of a pneumatic actuator and powder butterfly valve is composed of two parts, with the actuator as the main body, to accept the pneumatic components control the output signal pressure as the driving force, through the control element to change the direction of the airflow, control valve. Has the advantages of simple structure, the butterfly plate wear, sealing and long service life, simple operation and other characteristics, so it can be applied to a variety of powder / particle material applications.
1, execution organs used VATTENs gear rack type structure, beautiful appearance, large output torque, the normal service life of a million times, maintenance free.
In 2, the valve body adopts lightweight high-pressure cast aluminum alloy, light weight
In 3, the valve plate is lined with a steel core wear-resistant polymeric material, and rubber sealing ring formed of high wear resistance of soft sealing, wear resistance and strong and can also be used
In 4, can be mounted on the hopper, silo, outlet of screw conveyor and pneumatic conveying pipeline
5, flange may need to select a single flange surface ( D ) or double flange surface ( S )
VA104S double flange butterfly valve with the same 2 flange. VA104D single flange butterfly valve is equipped with an extended ring for installation of flexible casing. According to the application requirements. Can be separately selected drive handle or a cylinder to drive the kit. Industrial design with special composite materials using the VA104 butterfly valve has a structure. Compact and lightweight, the butterfly plate seal wear, long life, easy installation and maintenance etc.
