## Product Summary

SL pneumatic fittings are **90 degree elbow speed control valves (L type throttle valves)** designed to regulate airflow and control cylinder speed in pneumatic systems.

With an integrated adjustable throttle mechanism, these valves allow precise control of airflow, improving motion stability and system efficiency in automation applications.

The **90° elbow (L type) structure** enables flexible installation in tight spaces while supporting directional air routing and compact system design.

SL series supports PU tube and nylon tube, with air as the working medium, maximum operating pressure of **0–0.9 MPa**, proof pressure up to **1.32 MPa**, and working temperature range of **0–60°C**.

**OEM and ODM customization services are available** for thread types, tube sizes, adjustment performance, and branding.
