TAEHA TH-4440-C Pulse Valve
The TAEHA TH-4440-C pulse valve meets top standards such as CE, UL, distributed by Tan Thanh in the Vietnam market.
The TH-4440-C model is a diaphragm pulse valve specifically designed for dust collector systems and pneumatic pulse dust collector cabinets. The valve body is made of highly durable solid die-cast aluminum, with inlet/outlet pipe connections via coupling connection, pipe size 1½”. The valve structure features a direct control integral solenoid, a double pilot stage structure with an exhaust port and Elastomer diaphragm, capable of providing a larger pulse flow and faster response compared to single-stage valves.
The TAEHA TH-4440-C pulse valve offers high efficiency, safety for dust collection systems, and is easy to install and maintain.
