Industrial-grade Chinese Double Gate Valve (Model: Z644TC) - Pneumatic Ceramic Double Gate Valve for Bin Pump Inlet/Outlet Control
Product Description
Z644TC Pneumatic Ceramic Double Gate Valve: A Wear-resistant Sealing Solution for Grey Silo Pump Systems
The Z644TC pneumatic ceramic double gate valve (also known as double plug valve or dry ash valve) is an industrial-grade actuating device specifically designed for dry powder material transportation scenarios. It is particularly suitable for controlling the medium at the discharge inlet of the grey silo pump. With the superior wear resistance of ceramic material and the automation advantage of pneumatic drive, it becomes an ideal choice for high-maintenance conditions in industries such as power, chemical engineering, and mining.
Core Performance and Structural Advantages
Superb wear resistance, longer service life The valve plates and valve seats are made of toughened engineering ceramics, with hardness far exceeding that of traditional metal materials. This enables them to effectively resist the erosion and wear caused by hard particle media such as coal ash and dry dust. Through actual testing, the static test in coal ash medium can reach over 200,000 times without compromising the seal, and the service life is much longer than that of ordinary metal valves, significantly reducing equipment replacement and maintenance costs.
Self-sealing, no leakage The valve adopts a spring pre-tightening design between the two gate plates. By utilizing the bidirectional flexible pressure of the spring, it achieves self-tightening sealing, meeting the bidirectional sealing requirements of low-pressure to medium-pressure conditions. At the same time, during the valve opening and closing process, the valve plate will rotate, forming a grinding and polishing effect with the valve seat. Even if there is a small amount of impurities on the sealing surface, they can be self-scraped off, maintaining zero leakage for a long time.
Anti-blocking self-cleaning, stable operation The valve body channel adopts an eccentric structure design. When opening, the material will form a vortex, automatically cleaning the internal cavity of the valve body of accumulated ash and clogged materials. Some models are reserved with a dust blowing port, which can be connected to an external air source for auxiliary cleaning, fundamentally solving the problems of accumulated ash and clogging in traditional valves. Combined with buffer compensation gaskets and dust prevention mechanisms, it further ensures the flexibility and structural stability under harsh conditions.
Pneumatic drive, wide compatibility It uses 0.4-0.6MPa pneumatic actuators, with rapid response and remote control capabilities. It supports local manual control, centralized control system signal control, and 4-20mA current automatic control for PLC/DCS systems, perfectly adapting to the requirements of automated production lines. The nominal diameter of the valve covers DN40-350mm, with a nominal pressure of 1.0-1.6MPa. The applicable temperature is typically ≤200℃ (customizable to 400℃ for high-temperature resistance). It can meet the parameter requirements of various scenarios. Applicable scenarios
Electric power industry: Dry ash removal systems of thermal power plants, discharge and inlet valves of hopper pumps, ash silo discharge valves, balance valves, etc.;
