Hydraulic Solutions for Connecting Under Pressure

Hydraulic circuits are used in a number of applications such as to power the efficient changeovers of attachments on heavy machinery and equipment.  Earth moving machinery and demolition equipment such as excavators must frequently change attachments such as hammers, breakers, jaws and grapples to carry out various work processes.  The efficient changing of attachments is necessary for productive and profitable work.

It can become very difficult or impossible to connect male and female couplers and adapters with locked pressure in the system.  The resistance from thermal pressure can develop even if the equipment is turned off, especially if exposed to heat and sunlight.  This resistance can build up in machinery or attachments during the work day if exposed to solar heat in as little time as one hour.

This built up residual pressure must be eliminated in order to couple attachments which may take time and expose potential safety risks.  The procedures that operators must complete to eliminate thermal pressure can undermine the advantage of time saved with quick change of attachments. 

Threaded Couplings for Pressurized Connections

Stucchi offers solutions for connecting under pressure with threaded couplings designed with features to allow connection without the need for additional tools or processes to relieve thermal pressure.  Our threaded, flat face couplings feature an internal valve to allow quick connect of male and female couplings where thermal or residual pressure exists.  The flat face design eliminates leakage and oil spillage during quick release even in conditions of resistance.

Stucchi’s flat face quick coupling design is the basis for ISO 16028, setting the industry standard for flat face quick couplings.  We provide hydraulic coupler solutions which optimize hydraulic flow with no leakage or contamination.  Threaded quick couplers provide added protection against premature wear when subjected to high mechanical stress to prevent brinelling. 

Stucchi offers hydraulic solutions for the efficient quick connect and quick release of couplings even under high residual pressure conditions.  Our skilled hydraulic specialists offer custom designed hydraulic solutions which improve productivity and safety.  Contact us to speak with a hydraulic engineer and learn how to improve your quick connect under pressure applications.
