5" 6" 8 Inch Safety PVC Diaphragm Valve , RPP Sanitary Diaphragm Valve

Plastic Diaphragm Valves Series UPVC diaphragm valves , DN15-DN250

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.

Polyvinyl chloride unplastizised offers the best value for money for many applications. PVC-U is also a universal material.. It’s in good property of anti-corrosion, mechanical property, light, easy to install. PVC resin mixed with different aids can result different properties PVC materials for many applications, today it acts as an important plastic material for industrial piping system.
