The latest pneumatic angle seat valve developed and manufactured by Donjoy Technology Co., Ltd. features a unique angled structure. This design makes it more space-efficient during installation and easily adaptable to various complex piping layouts. It mainly consists of a valve body, pneumatic actuator, valve core, and valve stem. The valve body is typically made of stainless steel or plastic and has an angled flow channel structure, allowing the fluid to turn 90° in the pipeline, effectively reducing fluid resistance. Depending on the mode of operation, it can be divided into single-acting and double-acting types.
Unique Design and Superior Performance Advantages
(I) Compact Structure, Space-Saving
It adopts a unique angle-seat structure design, which allows the valve to occupy minimal space during installation, making it particularly suitable for industrial piping systems with limited space. Thanks to its compact size, the pneumatic angle-seat valve can be easily installed in various narrow locations, saving valuable space and allowing for a more compact and rational layout of the piping system.
(II) Low Flow Resistance, High Efficiency and Energy Saving
Its internal flow channel design has been carefully optimized to maintain a relatively stable flow rate as the fluid passes through the valve, reducing the impact and wear of the fluid on the valve, thereby greatly reducing flow resistance. In industrial production, the fluid can flow more smoothly without consuming excessive energy to overcome resistance, effectively improving production efficiency and reducing energy costs.
(III) Noise-Free, Quiet Operation
During the opening and closing process of the valve, special cushioning design and high-quality sealing materials are used to effectively avoid collisions and friction between components, thus achieving noise-free opening and closing. This advantage is particularly important in applications with strict environmental noise requirements.
(IV) No Dead Corners, Easy Cleaning
Its internal structure design eliminates dead corners, preventing the accumulation of dirt and impurities. In industries with extremely high hygiene requirements, such as food and pharmaceuticals, the no-dead-corner design of the pneumatic angle-seat valve makes cleaning easier and more efficient, ensuring that there is no residual material inside the valve, effectively guaranteeing product quality and safety, and preventing food safety incidents caused by hygiene problems.
(V) Zero Leakage, Safe and Reliable
Through the use of advanced sealing technology and high-quality sealing materials, this pneumatic angle-seat valve achieves excellent zero-leakage performance. In industries such as chemical and natural gas, the zero-leakage characteristic of the pneumatic angle-seat valve provides reliable safety assurance for production in these industries.
Innovative Features, Flexible and Versatile
(VI) Replaceable Valve Disc, Meeting Diverse Needs
It also features a replaceable valve disc, allowing users to freely replace the standard valve disc with a regulating valve disc according to different working conditions. Replacing the valve disc is very simple and does not require professional technicians or complex tools; ordinary workers can operate it skillfully after simple training. Technical Specifications:
