Yone Flanged Orifice Air Vent Valve FIG.211 – High-Performance Air Vent Solution for Water Pipeline Systems


Introduction: The Importance of Valves in Industrial Systems

Valves are the unsung heroes of modern industry. Whether in water treatment, oil and gas, chemical processing, or power generation, valves serve a critical function—controlling, isolating, and regulating the flow of fluids. In complex industrial pipeline networks, air pockets and gas accumulation can cause serious inefficiencies, pressure inconsistencies, and even equipment damage. This is where specialized valves, such as air vent valves, become indispensable.

Air vent valves are designed to automatically release trapped air in fluid systems, ensuring uninterrupted flow and system safety. Unlike control valves, ball valves, gate valves, or check valves, air vent valves focus specifically on the discharge of air to prevent air hammer, flow blockage, and cavitation. The Yone Flanged Orifice Air Vent Valve FIG.211 is engineered precisely for this purpose, offering reliable air release in demanding water pipeline environments.


Product Description: Yone Flanged Orifice Air Vent Valve FIG.211

The Yone Flanged Orifice Air Vent Valve FIG.211 is a high-quality, flanged-type air vent valve engineered for automatic air release in water supply pipelines. Developed with robust materials and a streamlined design, this valve ensures durability, efficiency, and long-term reliability.

Core Function

This valve is a safety device that releases trapped air within water piping systems to prevent air-related issues. Excess air in a pipeline can cause erratic flow, reduced pumping efficiency, and water hammer. The FIG.211 provides automatic venting without interrupting the flow or requiring manual intervention.

Key Features and Materials

The Yone FIG.211 model is built with high-quality materials to withstand harsh water service environments:

  • Body Material: Ductile Iron – known for excellent strength, impact resistance, and corrosion durability.

  • Orifice Cover: Ductile Iron – provides additional structural integrity for sealing and housing the internal components.

  • Float Ball: ABS (ISO2580) – lightweight, corrosion-resistant, and durable under fluctuating pressure conditions.

  • Air Release Nipple & Screw Plug: Brass – offers resistance to corrosion and ensures tight sealing performance.

  • Seal: EPDM Ball Seal Orifice – EPDM is a high-grade elastomer ideal for potable water and resistant to a wide range of temperatures and chemicals.

These material choices ensure that the valve remains functional even under prolonged exposure to water and atmospheric conditions.

Pressure Ratings and Standards

To accommodate various system requirements, the Yone Flanged Orifice Air Vent Valve FIG.211 conforms to multiple international pressure standards:

  • Class 125

  • JIS 10K

  • PN 16

This multi-standard rating allows for broad application flexibility across global infrastructure projects, making it a suitable choice for contractors and engineers working under different regulatory frameworks.

Size Range and Configuration

  • Available Sizes: 2” through 8”

  • Connection Type: Flanged end for secure, high-integrity pipe integration

The flanged configuration ensures stable installation and easy maintenance access, especially in industrial settings where vibration and pressure surges are common.


Applications of the Yone Orifice Air Vent Valve FIG.211

The Yone FIG.211 air vent valve is specifically designed for water pipeline systems, especially where long-distance fluid transportation is involved. This valve ensures safe and efficient discharge of entrapped air during filling and operation phases. Some common application sectors include:

1. Municipal Water Supply Networks

Urban and rural water systems depend on stable pressure and flow. Air vent valves like the FIG.211 prevent air blockage and help maintain consistent water delivery.

2. Irrigation Systems

In large-scale agricultural irrigation pipelines, air accumulation can severely disrupt water distribution. The Yone air vent valve ensures uninterrupted irrigation performance.

3. Water Treatment Plants

In water purification and processing facilities, the removal of air is essential to prevent turbulence and enhance flow meter accuracy.

4. Pump Stations

Air vent valves are critical in pump discharge pipelines, preventing cavitation and pump performance degradation caused by air entrapment.

5. Firefighting Water Lines

Emergency fire protection systems must be primed at all times. The Yone air vent valve ensures air is expelled automatically so water is available on demand.

6. Industrial Water Circulation Systems

Factories and power plants using water as a coolant or transport medium rely on air vent valves to maintain optimal thermal efficiency.
