Compact Dual Pilot Hydraulic Lock for Equipment with Yss-8BS

This bidirectional hydraulic lock serves as a safety device to prevent uncontrolled cylinder movement. It functions as a dual pilot check valve that provides reliable load holding in both directions, ensuring stable operation even under heavy-duty working conditions.

Yes, this excavator hydraulic lock with G3/8 BSPP port is specifically designed for compact and mini excavators. Its compact footprint and high pressure rating make it ideal for mobile machinery requiring precise cylinder position control and anti-slip protection.

Unlike a standard one-way check valve, this dual pilot check valve allows controlled reverse flow when pilot pressure is applied. The SYS08/42 series features integrated pilot-operated unlocking on both ports, enabling smooth bidirectional actuation while maintaining positive load holding when de-energized.

This heavy-duty hydraulic lock is rated for continuous high pressure operation up to 350 bar (5,075 psi). The hardened steel seat and precision-machined spool ensure leak-free load holding performance and smooth operation throughout its service life in demanding industrial applications.

Absolutely. This anti-slip hydraulic lock automatically closes both flow paths instantly if supply pressure is lost due to hose rupture or pump failure. The mechanically seated pilot check valve design guarantees zero-leakage load holding, protecting personnel and equipment from catastrophic cylinder drift.
