Product Description

The PZ73TC ceramic knife gate valve has a wide range of applications, from coal selection, gangue and slag discharge in mines and power plants, to urban sewage treatment; from slurry conveyance in cement and paper mills, to food, sanitation, and professional pipelines. The ultra-thin knife gate valve, with its small size, light weight, low flow resistance, non-gangue accumulation, ease of installation, and disassembly, has completely solved the complex issues of high flow resistance, space occupation, gangue accumulation, and difficulty in installation and maintenance associated with ordinary gate valves, flat gate valves, ball valves, stop valves, regulating valves, and butterfly valves. Consequently, a large number of general-purpose cut-off valves and regulating valves have been replaced by knife gate valves.

Product Overview

Ceramic knife gate valves can be equipped with electric or pneumatic actuators. By using accessories such as solenoid valves and proximity switches, they can achieve control of the open and close positions as well as signal output, and can also perform automatic control of continuous actions. Users can choose according to their actual needs. Suitable for industries such as chemicals, coal, sugar production, wastewater treatment, and papermaking, they are an ideal sealing valve. Particularly suitable for regulating and throttling in pipelines in the papermaking industry.

Product Features

1. Sealing Surface Materials: Two types available, structural ceramics or ultra-hard surface alloy materials.
2. Suitable for gas-solid mixed mediums like coal slag and ash slag, the gate, valve seat, and flow path sections are made of structural ceramic materials, offering wear resistance and a long service life.
3. Superior sealing performance and capable of seal surface repair.
4. Imported valve seats can serve as scraper plates, closing smoothly even in the presence of dust.
5. The valve body structure completely avoids issues of jamming and dust accumulation.
6. Drive Methods: Manual, pneumatic, and electric, etc.

Optional Accessories
