There are two main categories of diaphragm valves: one type seals over a “weir” (saddle) and the other (sometimes called a “full bore or straight-through” valve) seals over a seat. In general, straight-through diaphragm valves are used in on-off applications and weir-type diaphragm valves are used for control or throttling applications. While diaphragm valves usually come in two-port forms (2/2-way diaphragm valve), they can also come with three ports (3/2-way diaphragm valves also called T-valves) and more (so called block-valves). When more than three ports are included, they generally require more than one diaphragm seat; however, special dual actuators can handle more ports with one membrane.

1. Working pressure:
DN50-DN125: 1.0Mpa -2.0Mpa
DN150-DN200: 0.6Mpa- 2.0Mpa
DN250-DN300: 0.4Mpa-1.6Mpa
2. Working temperature:
NR: -20℃～+450℃
3. Face to face: EN588-1 /ANSI B 16.10
4. Flange connection according to EN1092-2, BS4504? ANSI B6.5
5. Testing: DIN3230, API598
1. Wide temperature range: -20°C-450°C
2. Excellent strength and toughness
3. Excellent chemical resistance
4. Flame retardant performance is self-extinguishing
5. low thermal conductivity, about 1/200 of steel
6. medium heavy ion content reaches ultrapure water standard
7. Health indicators meet the requirements of national health standards
8. The inner wall of the valve is smooth and smooth, and has small frictional resistance and adhesion when conveying fluid.
9. Easy to install, can be used for bonding. Thread. Flange and other ways to connect.
10. Excellent aging and UV resistance, which makes the normal service life much longer than other valve systems. As a new type of material, CPVC material has excellent corrosion resistance. It has been widely used in steel, metallurgy, petroleum, chemical, fertilizer, dye, pharmaceutical, electric power, environmental protection and sewage treatment industries in recent years. It is am metal anticorrosive material. The ideal alternative.
Diaphragm Valves are ideally suited for:
- Corrosive applications, where the body and diaphragm materials can be chosen for chemical compatibility. (E.G. Acids, Bases etc.)
- Abrasive applications, where the body lining can be designed to withstand abrasion and the diaphragm can be easily replaced once worn out
- Solids entrained liquids, since the diaphragm can seal around any entrained solids and provide positive seal
- Slurries, since the diaphragm can seal around entrained solids and provide positive seal
