Introduction to Hefeng Technology Sanitary Diaphragm Valve:

The sanitary diaphragm valve produced by Hefeng Technology meets the process requirements of cleanliness and sterility. Widely used in the food and biopharmaceutical industries, as well as the ultra pure industry, microelectronics industry, and fine chemical industry. Suitable for industries such as purified water systems, injection water (WFI), fine chemicals, and daily chemical products.

Hefeng Technology Sanitary Diaphragm Valvefeature

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.
