JL200气动角座阀的启闭件是塞形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动。阀杆的运动形式，有升降杆式（阀杆升降，手轮不升降），也有升降旋转杆式（手轮与阀杆一起旋转升降，螺母设在阀体上）。气动角座阀只适用于全开和全关，不允许作调节和节流。

气动角座阀

气动角座阀是一种采用气动执行机构控制、阀体呈90°角式结构的自动阀门。它集成了角座阀的流路优势和气缸的自动化优点，通过压缩空气驱动，实现快速启闭或比例调节，特别适用于需要频繁操作、快速响应和远程控制的自动化流体控制场合。

气动角座阀其核心设计特点和关键技术包括：

角式阀体设计 (Angular Body Design): 阀体呈90°直角，进口与出口垂直。这种设计使流体产生自上而下的流动路径。当阀门关闭时，流体压力有助于将阀芯紧压在阀座上，实现更紧密的密封，同时能有效降低水锤效应。它可直接安装在管道拐角处，节省安装空间。

气动执行机构 (Pneumatic Actuator): 采用单作用（弹簧复位）或双作用气缸作为驱动源。通过电磁阀控制压缩空气的通断，驱动活塞运动，从而带动阀杆和阀芯实现快速、稳定启闭动作（通常为两位式开关）。响应速度快，使用寿命长。

气动角座阀高性能密封与流量特性: 阀芯通常采用PTFE（聚四氟乙烯）或PEEK等高性能密封材料，耐腐蚀、耐磨损，确保严密关闭。流道通畅，流量系数（Cv值）大，压力损失小。阀芯的特殊设计可实现接近快开或等百分比的流量特性。

气动角座阀多功能与安全性: 单作用型号在失气时可依靠弹簧自动复位至常开或常闭的安全位置，保障工艺安全。可配备位置指示器、手动操作装置、限位开关等附件，实现状态监控和本地操作。

气动角座阀应用领域:

广泛应用于食品饮料、制药、生物工程、水处理、纺织印染、化工及轻工业的自动化生产线中，用于控制蒸汽、水、气体、液体、油品等介质的通断。

气动角座阀核心价值:

提供了一种结构紧凑、动作迅速、密封性好、易于自动化的清洁型阀门解决方案，是现代自动化流程控制中不可或缺的高性价比执行元件。

Product Name: Pneumatic Angle Seat Valve

Product Overview:

The Pneumatic Angle Seat Valve is an automated valve that utilizes a pneumatic actuator for control  features a 90-degree angled body. It combines the flow path advantages of an angle seat valve with the automation benefits of an air cylinder. Driven by compressed air, it enables rapid on/off operation  proportional control, making it particularly suitable for automated fluid control applications that require frequent operation, fast response,  remote control.

Its core design features  key technologies include:

Angular Body Design: The valve body has a 90-degree right angle, with the inlet  outlet perpendicular to each other. This design creates a top-to-bottom flow path. When the valve closes, the fluid pressure assists in pressing the piston (plug) tightly against the seat, achieving tighter sealing. It also helps reduce the water hammer effect. It can be installed directly at a pipeline corner, saving space.

Pneumatic Actuator: Employs a single-acting (spring return)  double-acting air cylinder as the power source. Controlled by a solenoid valve, the compressed air drives the piston movement, which in turn drives the stem  plug to achieve fast  reliable opening/closing action (typically two-position on/off). It offers fast response  a long service life.

High-Performance Sealing & Flow Characteristics: The piston seal is typically made of high-performance materials like PTFE (Teflon)  PEEK, providing excellent corrosion  wear resistance, ensuring tight shut-off. The flow path is smooth, offering a high flow coefficient (Cv value)  low pressure drop. Special piston designs can achieve near quick-opening  equal percentage flow characteristics.

Versatility & Safety: Single-acting models automatically return to a fail-safe position (normally open  normally closed) via the spring in case of air failure, ensuring process safety. Can be equipped with accessories such as position indicators, manual overrides,  limit switches for status monitoring  local operation.

Applications:

Widely used in automated production lines across industries like food & beverage, pharmaceuticals, biotechnology, water treatment, textile printing & dyeing, chemical,  light industry for controlling the flow of media such as steam, water, gas, liquids,  oils.

Core Value:

It provides a compact, fast-acting, well-sealed,  easily automated clean valve solution. It is an indispensable  cost-effective actuation component in modern automated process control systems.
