Manual Diaphragm Valves

Diaphragm valves offer many combinations of body and elastomeric diaphragm materials. The valve design is abrasion resistant and non-clogging. When the diaphragm, which is connected to the stem of the valve by a compressor, is pulled away from the bottom of the valve body or weir, the path of the fluid has smooth, streamlined flow. Slurries at low pressure that would normally clog most other valve designs easily pass through a diaphragm valve. The bonnet and working parts are completely isolated from the line fluid and only the body diaphragm materials must be considered for service compatibility. The valve is a top-entry design, allowing in-line maintenance. The valve is suitable for throttling and ON/OFF service in applications ranging from water treatment to chemical abrasion processes. Diaphragm valves are operated manually, electrically, or pneumatically.
