APPLICATIONS
Construction Equipment
Controlled lowering: During descent (e.g. lowering a platform), they regulate downward speed, preventing free-fall and protecting both operator and equipment
Mining Shaft Conveyance
Soft‑braking control: Hydraulic perform smooth, monitored braking for emergency stops—reducing stress on components and ropes
Winches
On hydraulic winches, integrated brake-release ports pilot brake engagement based on load: brakes remain locked until pilot pressure triggers safe release, preventing overruns
BRAKE RELEASE VALVE
Lynch brake release valves are a series of compact parking brake release valves that are typically installed in mobile applications. As a safety mechanism, it is designed to ensure the parking brake is always engaged to hold loaded motors and released on motor start-up. The valve package setting is proportional to the pressure in the braking piston chamber, thus allowing for soft disengagement and reengagement of the brake for various motor brake sizes.
FEATURES AND BENEFITS
- Multiple sizes for different flow requirements.
- High reliability and fast-acting.
- Adjustable brake engagement settings to adapt to brake specifications.
