Product Description

Customized for Gulf harsh desert environment, our gear operated lug centric butterfly valve adopts thickened cast iron housing with reinforced anti-rust and anti-scale coating to cope with local high-hardness sediment-rich water. The fully sealed gear actuator avoids sand intrusion and transmission failure under long-term outdoor high temperature exposure. Lug connection structure offers firm installation on buried main pipelines of residential compounds and municipal water supply projects. High temperature resistant sealing rubber maintains leak-proof performance in hot weather, and manual drive design works normally without power supply, widely used in water supply, drainage and irrigation projects in Saudi Arabia, UAE and Qatar. Large bulk supply and customized specifications are supported for local engineering contractors.

A **plate flange** is a flat, circular disk used to connect pipes, valves, pumps, and other equipment in a piping system. It is typically welded or bolted to the pipe and then joined to another flange with bolts and a gasket to create a secure, leak-proof seal.

### **Types of Plate Flanges:**
1. **Flat Face (FF) Flange** - The sealing surface is flat, suitable for low-pressure applications.
2. **Raised Face (RF) Flange** - Has a small raised area around the bore for better sealing.
3. **Ring-Type Joint (RTJ) Flange** - Features a groove for a metal ring gasket, used in high-pressure systems.
4. **Lap Joint Flange** - Used with a stub end, allowing easy alignment and disassembly.
5. **Threaded Flange** - Has internal threads for screwing onto pipes without welding.

### **Common Materials:**
- Carbon steel (ASTM A105)
- Stainless steel (ASTM A182 F304, F316)
- Alloy steel
- Ductile iron

### **Standards:**
- **ASME B16.5** - Covers dimensions for flanges up to 24 inches.
- **ASME B16.47** - For larger flanges (26 inches and above).
- **EN 1092-1** - European standard for flanges.

### **Applications:**
- Oil & gas pipelines
- Water treatment plants
- Chemical processing
- HVAC systems
