Diaphragm Valves
Diaphragm valves use a flexible diaphragm to control flow and separate the process fluid from the operating mechanism. Selection depends on the body design, diaphragm material, connections and process requirements.

Body & Connections
Define the body design, material and installation connections.
Process & Maintenance
Review cleaning, access and maintenance requirements for the application.
Diaphragm Material and Fluid Compatibility
Provide the fluid name, concentration, operating temperature and any cleaning chemicals. The diaphragm must be checked against both process and cleaning conditions. Specify whether the duty is continuous or intermittent and include the expected operating cycle.
Body Design and Pipe Connections
Define the valve body arrangement, wetted materials and any lining requirements. Provide the pipe size, connection standard and available installation space. Confirm the full wetted construction for the selected model rather than choosing from the diaphragm material alone.
Operation, Cleaning and Maintenance
State whether manual or automated operation is required and describe the switching frequency. Include cleaning requirements and access for diaphragm inspection or replacement. Any hygienic, drainability or documentation requirements must be checked for the exact valve configuration.
