DN200 WCB Air release valves exported to Saudi water plant
Recently, a batch of DN200 WCB carbon steel compound air release valves manufactured by Jinbin Valve have passed inspection and packaging procedures, and been delivered to Saudi Arabia for the water transmission pipeline project of a local water plant.
This air release valve is integrally cast from WCB carbon steel, fitted with a stainless steel strainer on the top to block sediment and impurities from entering the valve chamber and prevent jamming of internal components. It integrates three core functions: rapid air venting, micro air release and vacuum breaking. It quickly exhausts trapped air during pipeline filling, continuously discharges tiny air bubbles during operation, and automatically replenishes air once water supply is cut off, which effectively suppresses water hammer and prevents pipeline rupture caused by negative pressure, making it ideal for long-distance water transmission under high-temperature conditions in Saudi Arabia.
The automatic air release valve boasts four core advantages as follows:
Triple air venting protection to eliminate hidden dangers of pipeline water hammer
It rapidly discharges massive trapped air the moment pipelines are filled with water, avoiding poor water flow caused by air blockage. During regular operation, it continuously separates micro air bubbles from water to prevent pipeline wall damage from cavitation erosion. When water pressure drops after shutdown, it automatically draws in air to counteract negative pressure, eliminating pipeline collapse and burst accidents, and greatly cutting maintenance costs for water plants.
Sediment-resistant stainless steel strainer, compatible with Middle East water quality
A thickened stainless steel filter screen is installed on the valve top to intercept sand, aquatic weeds and debris, preventing valve spool jamming and malfunction. It perfectly adapts to sand-laden raw water transportation in Saudi Arabia and reduces frequent maintenance work.
WCB carbon steel with full epoxy anti-corrosion coating, heat-resistant and sea transport resistant
The integrally cast WCB steel valve body is rated PN64 for high pressure service. Internal and external epoxy coating enables it to withstand year-round intense high temperature in the Middle East and resist rust during long-distance ocean shipping, delivering a far longer service life than ordinary cast iron air release valves.
Large bore flow design for main pipelines of large-scale water plants
The DN200 large-diameter structure provides sufficient vent flow capacity, suitable for long-distance, high-flow municipal water transmission mains. A single valve can meet the air venting demands of large pipelines and reduce the total quantity of valves installed on the pipeline system.
Jinbin Valve specializes in supplying full-range air release valves for waterworks, with customized options including WCB carbon steel, stainless steel and ductile iron.
