Description
Buy Top Entry Ceramic Plug Valve HG5-89 | Dual Pressure Class SS Body Pneumatic Operation
This top-mounted discharge valve by VALVEHU is engineered for high-performance material drainage and bottom-discharge applications in demanding industrial environments. Designed under the HG5-89 standard, this valve integrates a ceramic-lined structure with a top-entry actuator system, delivering both mechanical resilience and corrosion resistance. It is widely deployed in chemical, pharmaceutical, food processing, and metallurgical systems where contamination control and thermal stability are paramount.
The internal body is lined or coated to withstand aggressive media and elevated temperatures. With sizes ranging from DN25 to DN200 and connection standards matching ISO-compliant flanges, this valve accommodates a wide range of reactor volumes and discharge pressures. It features precision-machined components for leak-proof shutoff and low-torque operation. The pneumatic actuator ensures fast, automated operation, suitable for continuous or batch processing environments.
Additionally, its Y-type angled design minimizes dead space and sediment accumulation, making it ideal for powder, slurry, or viscous media handling. The ceramic-plug sealing mechanism is especially favored in applications with high abrasion or thermal cycling, maintaining long service life and reducing downtime.
Whether you are specifying valves for a new installation or replacing existing units, this industrial-grade solution guarantees superior control and discharge accuracy.
