PVDF/PTFE flanged diaphragm valve, weir type, flange end ANSI#150, JIS10K, DIN standard

Diaphragm valves offer many combinations of body materials 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 a smooth, streamlined flow. Slurries at low pressure that would normally clog most other valve designs easily pass through a diaphragm valve. The valve has a top-entry design, allowing in-line maintenance; it 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.

PVDF is short for Poly Vinylidene Fluoride, it has excellent chemical stability, excellent chemical resistance, and excellent thermal stability. It can be long operated under the temperature from -62 to 150.Furthermore, it’s one of the perfect insulation materials with a high dielectric constant, which can resist all mediums like salt acid, alkaline, arene, halogen and so on except for hydrochloric acid and strong solvent. It also enjoys the merits like no flame, breaking resistance, wear resistance and good self lubricating property.
