Q641TC Pneumatic Ceramic Ball Valve

Q641TC Pneumatic Ceramic Ball ValveProduct Introduction

Q641TC Pneumatic Ceramic Ball ValveIt is a high-performance valve made of structural ceramics as the core material, combined with pneumatic drive, which has advantages such as wear resistance, corrosion resistance, and high temperature resistance. It is widely used in the field of fluid control under high demanding working conditions.

Core performance and material advantages

Material characteristics: Key components such as spheres, valve seats, and liners in contact with the medium are made of structural ceramic materials (such as zirconia ZrO?)? Aluminum oxide has a Rockwell hardness of HRC88~90 and excellent chemical stability, second only to diamond. The valve body material can be selected from carbon steel, stainless steel (such as SS304, SS316L) or forged steel to meet different strength and corrosion resistance requirements.

Performance Highlights: Zero Leakage Sealing: The valve ball and seat are precisely ground to form a surface contact hard seal, combined with ceramic self-lubricating properties, achieving zero leakage effect with light torque and low resistance; Ultra long lifespan: The wear resistance is 2-4 times that of titanium valves, suitable for long-term operation in high particle and highly corrosive media; Wide temperature adaptability: The working temperature range covers -20 ° C~550 ° C, suitable for high-temperature steam, mud and other working conditions.

Structural features: Adopting a three-stage valve body design, high strength and smooth flow channel; Built in buffer compensation elastic gasket to prevent blockage or ball breakage caused by impurity media.

Q641TC Pneumatic Ceramic Ball ValveInstallation points and maintenance guide

Q641TC Pneumatic Ceramic Ball ValveDue to its wear resistance, corrosion resistance and other characteristics, it is widely used in harsh working conditions. Its installation and maintenance must strictly follow the specifications to ensure stable performance. The following will explain the installation process, maintenance points, and precautions.

Product installation specifications

Preparation before installation: Before installation, the entire machine needs to be tested according to the specified signal (pneumatic or electric) to prevent transportation vibration from affecting performance. Only after passing the test can it be installed online. Wiring should refer to the circuit diagram of the electric actuator. At the same time, residual impurities (such as welding slag, rust, etc.) in the pipeline need to be removed to avoid damaging the valve seat and sphere; Remove the flange end protective cover and rinse and clean the pipeline with the valve open.

Key points of installation operation

Pipeline requirements: The pipeline near the installation point should not be lowered or subjected to external forces, and supports should be used to eliminate pipeline deviation; After connecting with the pipeline, cross tighten the flange bolts according to the specified torque.

Lifting taboos: It is prohibited to use the actuator as the lifting point to avoid damaging the components.

Installation direction: It can be installed horizontally or vertically.

Connection standards: Flange connections must comply with standards such as GB/T9113 and JB/T79.1, and different diameters correspond to different flange sizes (such as DN15 flange diameter of 95mm and DN100 flange diameter of 220mm).

Product Performance and Maintenance Fundamentals

Core performance advantages

Material characteristics: The part in contact with the medium is structural ceramic (such as zirconia ZrO?)? Aluminum oxide Al? O? ）Rockwell hardness HRC90, high chemical stability, second only to diamond.

Adaptability to working conditions: high temperature resistance (-20 ° C~550 ° C), good insulation, small thermal expansion, suitable for high hardness particles and strong corrosive media (such as acid, alkali, salt, mud).

Sealing and torque: The sphere is precision ground and utilizes ceramic self-lubricating properties to achieve zero leakage, with low torque and smooth switching.

Daily maintenance and troubleshooting

Regular inspection items

Sealing performance: Observe whether there is any medium leakage. The hard sealing structure should ensure zero leakage.

Execution mechanism: Check whether the pneumatic signal is normal and whether the air source pressure is stable (usually 0.4~0.6MPa).

Ceramic components: If conveying media containing particles, it is necessary to regularly check the wear of the valve ball and seat, and replace them if they are severely worn (with a service life of 2-4 times that of titanium valves).

Common fault handling

Blockage: When impurities enter, it needs to be disassembled and rinsed. The built-in buffer compensation gasket can reduce the risk of jamming.

Leakage: If the sealing surface is damaged, the ceramic valve seat/sphere needs to be re ground or replaced.

Increased torque: It may be due to wear or insufficient lubrication on the ceramic surface, and high-temperature grease (such as graphite based grease) can be applied.
