Pneumatic Double Disc Ceramic Gate Valve

Pneumatic Double Disc Ceramic Gate Valve designed to for on-off service in venting and conveying lines on high pressure pneumatic conveying applications. Double disc valve uses a double disc sealing and sealing surfaces are made from wear-resistant alloy or ceramic The design is rugged and clean operating. The Double disc valves have metal to metal sealing to reduce wear in venting and discharge applications. The seal is 100% airtight and the valve achieves a long service life, particularly in applications. Consequently, overall system reliability is increased dramatically.
The GZT644TC Pneumatic Double Disc Ceramic Gate Valve is mainly used in feeding and dumping the dry powder and the transport pipeline, which not only adopt toughening ceramic as shut off and wear out resistance material, but also design construction of pressure self-sealing and valve disc auto-rotate, so as to the sealing surface within the dry powder get more wear resistance in process of opening and closing frequently, thereby, which guarantee the high requirements of sealing performance of this valve and long working

The GZT644TC Pneumatic Double Disc Ceramic Gate Valve is equipped with a ceramic liner inside the body, contributing to its exceptional performance in dry ash conveying systems and hopper pumps. This type of valve is especially well-suited for high-abrasion industries, such as mining, papermaking, chemicals, etc. The valve's ability to withstand high levels of wear and tear makes it a valuable asset in these demanding fields. Moreover, it's designed to function efficiently at temperatures up to 200℃, further emphasizing its versatility and robustness in various industrial applications.
The GZT644TC Pneumatic Double Disc Ceramic Gate Valve is a robust and versatile valve system offering many unique features and benefits. This guide will cover its installation, use, maintenance, structural features, working principle, parts and materials, and application specifications.

Features:

Sealing pair is made of structural ceramics,which have perfect performance to resist wear and

Two-side sealing can realized due to double disc structure of the pneumatic ceramic double disc gate

It inserts spring between double valve discs to ensure self- sealing through bi-directional flexible preload pressure of spring, having characteristics of low pressure bi-directional sealing and without dust clogging phenomenon in the process of the opening and closing of

The valve disc rotational motion can avoid the ash deposition on the sealing surface during opening and closing, so the valves have much longer

The blow sweep port or automatic blow sweep device can be set on the valve body according to different operating
