Project Cases












Double Orifice Air Release Valve
The Double Orifice Air Release Valve features two separate orifices designed for different functions - a small orifice for continuous air release under pressure and a large orifice for rapid air exhaust during pipeline filling and vacuum relief during draining. Ideal for high points in water transmission pipelines.
Technical Specifications
- Size Range: DN50 - DN200
- Pressure Rating: PN10, PN16
- Material: Ductile iron, Stainless steel trim
- Orifice Sizes: Small: 2-3mm, Large: Full bore
- Sealing: EPDM, NBR
- Application: Water transmission, pumping stations

Single Air Release Valve
The Single Air Release Valve is designed to release accumulated air from pressurized pipelines. Compact and efficient, it maintains system efficiency by preventing air pockets that can reduce flow capacity and cause water hammer effects in water distribution systems.
Technical Specifications
- Size Range: DN15 - DN100
- Pressure Rating: PN10, PN16
- Material: Brass, Cast iron, Stainless steel
- Float: Stainless steel
- Temperature Range: -10°C to 70°C
- Connection: Threaded, Flanged
