JOIL JIHI80 3" Submerged Pulse Jet Valve With Optional JOIL Solenoid Coil &

Product Description:

The Korea JOIL Asahi JIHI80 is a high-performance 3-inch submerged (manifold) diaphragm pulse valve engineered for reverse pulse filter cleaning in industrial dust collectors and baghouse systems. As the compressed air “switch” in pulse jet dust collector systems, this valve is controlled by electrical signals from a pulse controller to deliver instantaneous, high-energy air bursts for effective filter bag cleaning. Based on the quality of JOIL pulse valves, the manufacturer offers a five-year free quality guarantee for all users of the Asahi brand pulse valves.

This valve features a submerged (淹没式) design, meaning the valve body is installed directly into the air manifold (air tank), offering superior flow characteristics and reduced pressure loss, making it ideal for low air pressure applications. The JIHI80 model has a 3-inch port size (DN80) with a Cv flow factor of 142 and an effective area of 3 inches.

The valve features a unique structural design that ensures rapid opening, high flow velocity, and low pressure loss. The special diaphragm sandwich design guarantees long service life and can handle various harsh working conditions, with a laboratory-tested life of 3 million cycles. The valve body is constructed from die-cast aluminum alloy with a corrosion-resistant coating. The diaphragm seat is made of NBR (elastomer). The pilot head uses magnetic materials and stainless steel isolation components. The coil is available with IP65 protection class for reliable operation in dusty and outdoor environments. The entire unit weighs approximately 3.82 kg.

Trusted by major global corporations including POSCO, Hyundai Heavy Industries, LG Chem, Nippon Steel, Lafarge Cement, Alcoa, and Mittal Steel, the Korea JOIL Asahi JIHI80 pulse valve delivers reliable, high-flow pulse jets for efficient dust removal and extended filter bag life.
