Semi automatic pneumatic sanitary butterfly valve supplier

Manual two-piece butterfly valve, stainless steel sanitary butterfly valve working principle:

Hefeng Technology is a type of valve that uses a circular disc as the opening and closing element and rotates with the valve stem to open, close, and regulate fluid channels. The disc is installed in the vertical direction of the pipeline. Inside the butterfly valve body, the circular disc rotates around the axis at an angle between 0 and 90 degrees. When rotated to 90 °, the valve is fully open. When the valve core comes into contact with the sealing ring of the butterfly valve, the torque of the actuator will increase. The KBFV control mode is divided into manual operation and pneumatic control. Pneumatic butterfly valves have three standard states: normally open (NO), normally closed (NC), and pneumatic/pneumatic (D/A).

　　Hefeng TechnologyThe manual two-piece butterfly valve KBV stainless steel sanitary butterfly valve is a sanitary and economical on/off valve that can be used in automatic or manual systems. Due to its large opening area, low fluid resistance, and relatively gentle treatment of products with low to medium viscosity, it has become the main solution for modern processing technology. This valve is used in food, dairy, brewing systems, and biopharmaceutical applications.

　　 Hefeng TechnologyManual two-piece butterfly valve, stainless steel sanitary butterfly valve features:

The valve body is available in casting and forging options, suitable for different usage needs of domestic and foreign customers.

The product specifications are complete, with any size from DN4 to DN80 to choose from.

Imported material film, with good corrosion resistance, in compliance with FDA and USP24 class6 certification.

The protruding ribs around the valve body and the corresponding positions of the diaphragm are interlocked and sealed, ensuring that the diaphragm can tightly seal with the valve body in both open and closed states, achieving "zero" residue, easy cleaning, and complying with EHEDG design standards.

The normally closed diaphragm structure makes manual switching more effortless.

The rotating handwheel can achieve excessive closure protection by adjusting the limit nut, ensuring that the diaphragm has the predetermined closing pressure, optimizing the safety of the sealing function, and extending the service life of the diaphragm.

The red switch display between the handwheel and the upper cover allows for visual inspection of the valve's on/off status and degree.

Pneumatic valves can be equipped with solenoid valves, position feedback or positioning regulators according to customer needs to achieve automatic control or flow regulation of the valve.
