What Is A Limit Valve?
The Limit Valve is a safety protection device in tipper truck hydraulic systems. As your professional provider of hydraulic system solutions for tipper trucks, Xi'an Yuesheng Xingyao Trading Co., Ltd. has meticulously engineered this valve with a reliable mechanical structure and precision manufacturing processes, specifically designed for safety limit protection in tipper truck lifting systems. It detects the lifting position through mechanical contact or proximity sensing, automatically cutting off or changing the oil circuit when reaching the preset limit position to prevent cylinder over-extension. Featuring accurate triggering, rapid response, strong durability, a simple structure, easy installation, and high reliability, this product effectively prevents cylinder overtravel and protects the entire lifting system from damage. It serves as an indispensable key component in tipper truck safety systems, providing an important safeguard for tipper truck operational safety.

FAQ
Q: How to determine the installation position of the limit valve?
A: Determine the installation position based on the cylinder's maximum stroke, ensuring timely triggering before reaching the limit position.
Q: How to choose between mechanical and proximity switch types?
A: Mechanical type offers lower cost and higher reliability; proximity switch type provides contactless operation and longer life. Choose based on specific requirements.
Q: How to troubleshoot false triggering?
A: Check for loose installation, worn trigger mechanism, or unreliable wiring.
Q: What should be noted when using in humid environments?
A: Select products with IP67 or higher protection rating and regularly inspect seal condition.
Q: How to adjust the limit position?
A: Mechanical type adjusts by changing installation position; proximity switch type adjusts by modifying detection distance.
