Working principle：
E-C series Injet type mixing proof valve involves several key components, including an actuator, connecting bracket, valve stem, and valve body. The actuator drives the valve stem to move linearly along the axial direction. When the valve stem moves upward, it opens both the upper and lower pipeline channels; conversely, downward movement closes the passage. Two sealing rings are integrated into the valve stem, forming an independent sealing cavity with the sealing surface of the valve body. This cavity is connected to a CIP (Clean-In-Place) valve and enables leak detection. Additionally, this design prevents cross-contamination between different media flowing through the upper and lower pipelines and supports monitoring functions.
Application range：
The double valve body mixing proof valve is developed based on the E-C series single-valve body mixing proof valve by incorporating an additional valve body at the bottom. This structural enhancement increases the flexibility of flow direction changes in the pipeline system, thereby satisfying more complex and diverse customer requirements regarding fluid routing.

Wide application range
The injet type mixing proof valve demonstrates excellent adaptability and can operate reliably under various complex industrial conditions, fulfilling diverse industry-specific needs. It is widely used across multiple sectors—from consumer goods industries such as food, beverage, and dairy processing—to highly regulated fields like pharmaceuticals, biotechnology, and fine chemicals. Furthermore, it is suitable for large-scale industrial applications including oil and gas production, natural gas processing, and water treatment systems. In food processing, the valve enables precise control over the mixing and transportation of raw ingredients according to specific production processes. In pharmaceutical manufacturing, it complies with GMP standards and ensures sterility and contamination-free operations. In chemical engineering environments, it performs reliably under harsh conditions such as high temperatures, high pressures, and strong corrosive media, ensuring process safety and operational stability.
