Ceramic slag discharge valve

Ceramic slag discharge valve is an industrial valve designed specifically for high wear and corrosive media, widely used in fields such as power, mining, and chemical engineering. Here is a summary of its key information:

1、 Product Overview
Ceramic slag discharge valve (such as PZ41TC model) is mainly used to cut off or connect solid-liquid two-phase flow media such as ash water mixture and slurry, with bidirectional sealing and wear-resistant characteristics. The valve body is made of carbon steel (WCB) material and lined with ZTA engineering ceramics, with wear resistance more than 10 times that of ordinary metals.
2、 Technical parameters
Pressure rating: PN1.6~PN6.4MPa (high pressure models can reach PN64).
Applicable temperature: -20 ℃~550 ℃ (customizable for special working conditions).
Diameter range: DN50~DN600 (square mouth can be customized).
Sealing material: Aluminum oxide ceramic (ZTA engineering ceramic).
3、 Structural characteristics
Wear resistant design
The valve plate and valve seat are both lined with ceramic, and the internal flow channel is optimized to prevent slag accumulation and medium erosion.
Drive mode
Supports manual, electric, pneumatic (such as PZ641TC), and bevel gear transmission.
Connection form
Flange connection (GB/DIN/ANSI standard), some models support clamp installation.
4、 Typical applications
Power industry: Ash discharge system and ash removal pipeline for thermal power plants.
Mining/chemical industry: slurry transportation, control of corrosive slurry.
Environmental engineering: sewage treatment, fly ash discharge.
