Laizhou Dongsheng Valve Co., Ltd - Non-Rising Stem Diaphragm Valve
Diaphragm valves offered by Laizhou Dongsheng Valve Co., Ltd. come in two main types: wire and full flow. These valves utilize a 'pinching' method that employs a flexible diaphragm to control flow and are often unsuitable for extremely high-temperature fluids. Primarily used in liquid systems, these valves are appreciated for their application in handling media such as solid fluids, water, and various chemicals including inorganic acids and alkaline liquids. The valves are designed to operate under specified working pressures that vary with size, such as 1.0MPa for DN50-DN125 sizes. They are constructed to meet standards like the EN588-1 for face-to-face configuration and incorporate flange connections in accordance with EN1092-2 and BS4504. Quality assurance is guaranteed through rigorous testing in line with DIN3230 and API598 standards. Laizhou Dongsheng Valve Co. supports long-term customer partnerships through certified production processes compliant with ISO9001 and CE standards.- Working pressure:
- DN50-DN125: 1.0Mpa
- DN150-DN200: 0.6Mpa
- DN250-DN300: 0.4Mpa
- Working temperature: NR: -20℃～+60℃
- Face to face: EN588-1
- Flange connection according to EN1092-2, BS4504 ect.
- Testing: DIN3230, API598
- Medium: Cement, Clay, Cinder, Granular Fertilizer, Solid fluid, Fresh Water, Sea Water, Inorganic acid and Alkaline Liquid etc.
Diaphragm Valves have two kinds of types, wire and full flow, which use a ‘pinching’ method to stop the valve flow using a flexible diaphragm.These types of valves are generally not suited for very high-temperature fluids and are mainly used on liquid systems.
