ASCO 8353H038 2-Way 1-1/2 Inch Solenoid Valve

ASCO 8353H038 is a 2-way, 2-position, normally closed solenoid valve designed as the main pulse valve for dust-collection systems. It features a 1-1/2 in NPT port size and an aluminum body built to withstand the rigors of industrial dust environments. The valve uses a Hytrel diaphragm and Buna‑N seals, delivering robust chemical and abrasion resistance suitable for dust-collector service, while a remote pilot connection (1/8 in NPT) allows control from a centralized pulsing system. With a flow coefficient of about 53 Cv, it can move large volumes of air quickly to purge collected dust across standard filter areas, contributing to consistent filtration efficiency. The 8353H038 is a 2/2 NC valve, meaning energizing the coil opens the valve for a purge cycle and releasing the coil returns it to the closed state, a behavior that aligns with typical pulse-cleaning sequences. This ASCO main pulse valve is commonly installed directly on dust-collector manifolds or upstream control blocks and is compatible with standard dust-collector piping fittings, making it a widely used option in mid- to large-scale industrial filtration systems.
