The internal pressure relief valve system is effective for easy connection when there is residual pressure.
The "VEP-P" screw-type flat face coupling series is a proposal from Stucchi suitable for high-pressure hydraulic applications and connections where residual pressure remains. This screw connection system prevents early wear and the sticking of the ball parts that can occur in circuits with high pulse pressure. The triple valve structure allows for safe connections without oil loss during attachment and detachment, even in situations with residual pressure. 【Features】 ○ Easy to clean, effectively reducing contamination intrusion into the system ○ Eliminates losses due to leakage of operating oil during attachment and detachment, reducing environmental impact ○ Minimizes air entrapment during attachment and detachment, aiding optimal system operation ○ The design of internal components is devised to minimize pressure loss, preventing a decrease in system efficiency ○ The internal pressure relief valve system is effective for easy connections in the presence of residual pressure For more details, please contact us or download the catalog.
