Pneumatic ceramic double disc valve Z644TC principle:

The pneumatic ceramic double gate valve Z644TC, also known as a ceramic parallel double gate valve or dry ash valve, is a type of ceramic valve. Therefore, its structure and working principle are consistent with that of a ceramic gate valve. The lifting and lowering motion of the valve body (gate plate) is driven by the valve rod, which moves the valve seat sealing surface, allowing or blocking the fluid passage. When the valve is partially open, a vortex is generated on the back of the gate plate, which can easily cause erosion and vibration of the gate plate, as well as damage to the valve seat sealing surface, making repairs difficult. It is usually suitable for conditions that do not require frequent opening and closing, and where the gate plate needs to be kept fully open or fully closed.

Pneumatic ceramic discharge valve Z644TC principle:

The pneumatic ceramic discharge valve Z644TC-10C is specifically designed for pneumatic ash removal systems, featuring reliable opening and closing actions with low starting loads; high wear resistance, minimal resistance, and reduced clogging and scaling; easy installation and maintenance, long service life, and excellent sealing performance. Its unique design concept lies in the valve plate's self-polishing and smoothing action on the sealing surface of the valve seat during operation, which continuously enhances its wear resistance and sealing performance under harsh operating conditions, thereby extending the valve's service life. The pneumatic actuator employs a pushrod-type straight cylinder drive, offering reliable performance with high output torque, suitable for operation under severe conditions.
