D-025L Combination Air Valve

Description

The D-025L combination air valve contains both an air & vacuum large orifice component and an automatic small orifice air release component in a single body. The valve is specifically designed to operate with liquids carrying solid particles.

The dual feature combination air valve discharges and admits air (gas) during the filling or emptying of the system, and releases accumulated air (gas) from the system while it is operating under pressure.

Applications

Desalination & Sea Water, Mines, Oil & Gas, Marine - Ballast
Water, Food Industry, Power Plant Cooling, CBM

Operation

The air & vacuum component discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during drainage and at water column separation.
High velocity air will not blow the float shut. Water will lift the float which activates the sealing of the valve.
At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.
The smooth discharge of air reduces pressure surges and other destructive phenomena.
The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.
The air release component releases entrapped air in pressurized systems.

Main Features

- Working pressure range: 0 - 16 bar (PN16)
- Sealing pressure range: 0.05 - 16 bar
- Testing pressure: 25 bar.
- Maximum working temperature: 60° C.
- Maximum intermittent temperature: 90° C.
Note: For applications requiring a working temperature above the maximum stated or below 5° C, please consult first with the Amiad Engineering Dept.

- The unique design of the valve prevents contact between the liquid and the sealing mechanism by creating an air gap at the top of the valve. These features are achieved by:
• The conical body shape: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length.
• Independent spring-guided linkage between the lower float/ rod assembly and the upper float sealing mechanism: allows free movement of the float and rod. Vibrations and movement of the
lower float due to turbulence will not unseal the upper float sealing mechanism.
• The Rolling Seal Mechanism: less sensitive to pressure differentials than a direct float seal. It accomplishes this by having a comparably large orifice for a wide pressure range (up to 16 bar).
• Funnel-shaped lower body: designed to ensure that residue matter will fall back into the system and be carried away by the main pipe.
- All inner metal parts made of stainless steel. Float made of composite materials.
- 1 ½” threaded discharge outlet enables connection of a vent pipe.
- Dynamic design allows for high capacity air discharge while preventing premature closure.
- The ball valve can be opened to release trapped pressure and drain the valve body prior to maintenance and for back-flushing during maintenance.

 

D-060 Combination Air Valve

Description

The D-060 series has the features of both an air release valve and an air & vacuum valve. The valve is designed to automatically release small pockets of built up air to the atmosphere during operation, and also automatically discharges or admits large volumes of air during the filling or draining of a pipeline.

Applications

- Municipal and industrial water conveyance systems.

Operation

The air & vacuum component, with the large orifice, discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.
High velocity air will not blow the float shut. Water will lift the float which seals the valve.
At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.
The smooth discharge of air reduces pressure surges and other destructive phenomena.
The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.
The air release component releases entrapped air in pressurized systems.

Main Features

Working pressure range:
D-060 0.2 - 16 bar
D-060-C 0.2 - 16 bar
D-062 0.2 - 25 bar
D-065 0.2 - 40 bar

- Testing pressure for the air valve is 1.5 times its working pressure.
- Maximum working temperature: 60°C.
- Maximum intermittent temperature: 90°C.
- All main flow cross-sections are equal or greater than the nominal port area.
- Aerodynamic design enables high flow rates of air both at intake and at discharge.
- Reliable operation reduces water hammer incidents.
- Dynamic design allows for high capacity air discharge while preventing premature closure.
- Special orifice seat design: bronze and E.P.D.M. rubber, assures long-term maintenance-free operation.
- Screen protected outlet.
- The upper screen is protected with a protective cover.

Air Release Component
- Body made of high strength materials.
- All operating parts are made of specially selected corrosion resistant polymer materials.
- Large size air release orifice:
• Dramatically reduces the possibility of obstruction by debris.
• Releases air at high flow rates.
• One size orifice for a wide pressure range (up to 40 bar), achieved by the rolling seal mechanism.
