Features

Our SSJ Series Threaded Needle Valve is engineered for precise airflow regulation in demanding pneumatic systems. Designed with a durable brass body and fine-thread needle, it enables smooth and accurate control over cylinder actuation speed, effectively minimizing shock and ensuring stable operation. The robust threaded (NPT/PT) connections ensure a secure, leak-proof seal, making it the ideal choice over plastic push-in fittings for high-vibration environments and industrial applications.

FAQ

Q: What's the difference between this and a standard quick-connect throttle fitting?

A: The main differences lie in the connection method and applicable scenarios. Quick-connect fittings are quicker to install and suitable for general applications using nylon tubing. This threaded connection, on the other hand, is more secure, offers higher pressure resistance, and is more shock-resistant. It's particularly suitable for applications subject to vibration, high temperatures, or when using soft metal or hydraulic tubing, offering superior reliability.

Q: Why doesn't the cylinder speed change significantly after adjusting the valve?

A: Possible causes include the following: ① Insufficient system pressure: Low air pressure will result in insufficient driving force and ineffective speed regulation. ② Excessive cylinder load: Excessive load can offset the throttling effect. ③ Internal leakage in the cylinder or valve: Check the cylinder piston seal and valve seal for integrity. ④ The speed control valve is installed in the wrong direction: Please ensure that you are throttling the air flow in the desired direction.
