1 Data Pack G Issued November Data Sheet Quick action couplings A range of double shut-off industrial quick action couplings. 60 Series Features 1. Hardened nipples and sleeves along with solid bar-stock construction assures long service life by providing maximum resistance to damage caused by hydraulic and mechanical shock. High flow capacity is the result of the large areas provided for flow through the valves. High pressure seal design. Nitrile O rings supported by Teflon back-up rings 4. Parker s cylindrical valve with its 60 metal to metal valve stop maintains valve alignment and ensures that poppets open fully every time 5. Captive valve seal assures bubble tight poppet sealing. The valve seal is positively captured by the metal poppet to minimise seal washout or damage from high fluid velocity 6. Durable ball locking mechanism assures reliable connections every time. Many ball bearings distribute the load while providing alignment and excellent swivelling action to reduce hose torque and prolong hose life. Applications 60 Series couplings incorporate valves in both the body and nipple halves to prevent fluid loss when the coupling is disconnected. These couplings are normally referred to as hydraulic couplings, but they are used extensively with other media where fluid loss on disconnect is objectionable.

System characteristics such as high cycling rates and/or high amplitude shocks, either hydraulic or mechanical, can reduce the functional life of a coupling, even if the system s nominal pressure is equal to or less than the rated pressure of the coupling. Temperatures exceeding that specified (see technical specification) will reduce the maximum operating pressure.

Design all systems and equipment in a fail-safe mode, so that failure of the quick action coupling or hose will not endanger persons or property. Ball locking quick action couplings can unintentionally disconnect if they are dragged over obstructions on the end of a hose or if the sleeve is bumped or moved enough to cause disconnection. Mechanical loads: External forces can significantly reduce quick action couplings life or cause failure. Mechanical loads which must be considered include excessive tensile or side loads, and vibration. Quick action couplings can be heated to destruction or loss of sealability without contact by such nearby items as hot manifolds or molten metal. The same heat source may then initiate a fire. This can occur despite the presence of cool air around the quick action couplings. Heating of plated parts, including quick action couplings and port adaptors, above C such as during welding, brazing or soldering may emit deadly gases and may cause coupling seal damage. Installation Ensure the quick action coupling maximum operating pressure (see technical specification) is equal to, or greater than the maximum system pressure. Surge pressures in the system, higher than the maximum operating pressure of the coupling, will shorten the quick action couplings life. Visually inspect and check for correct style and material. Coupling should be connected and disconnected with a sample of the mating half with which they will be used. If different manufacturer s component parts are to be used in the same system, the lowest pressure rating of the two halves should not be exceeded. Use a thread sealant, lubricant or a combination of both when assembling pipe thread joints in quick action couplings. Be sure the sealant is compatible with the system fluid or gas. To avoid system contamination, use a liquid or paste type sealant rather than a tape style. Use the flats provided to hold the quick action coupling when installing fittings. Do not use pipe wrenches or a vice on other parts of the coupling to hold it when installing or removing fittings as damage or loosening of threaded joints in the coupling assembly could result. Do not apply excessive torque to taper pipe threads because cracking or splitting of the female component can result. Locate quick action couplings where they can be reached for connect or disconnect without exposing the operator to slipping, falling, getting sprayed, or coming in contact with hot or moving parts. Use dust caps and plugs when quick action couplings are not coupled to exclude dirt and contamination and to protect critical surfaces from damage. Use a hose whip (a short length of hose between the tool and the coupling half) instead of rigidly mounting a coupling half on hand tools or other devices. This reduces the potential for coupling damage if the tool is dropped and provides some isolation from mechanical vibration which could cause uncoupling. Maintenance of quick action couplings Even with proper selection and installation, quick action coupling life may be significantly reduced without a continuing maintenance programme. Frequency should be determined by the severity of the application and risk potential. A maintenance programme must be established and followed by the user and must include the following as a minimum: Visual inspection of quick action couplings: Any of the following conditions require immediate shut down and replacement of the quick action coupling: Cracked, damaged, or corroded quick action coupling parts Leaks at the fitting, valve or mating seal Broken coupling mounting hardware, especially breakaway clamps. Visual inspection all other: The following items must be tightened, repaired or replaced as required: Leaking seals or port connections Remove excess dirt build-up on the coupling locking means or on the interface area of either coupling half Clamps, guards and shields System fluid level, fluid type and any air entrapment. Functional test: Operate the system at maximum operating pressure and check for possible malfunctions and freedom from leaks. Personnel must avoid potential hazardous areas while testing and using the system. Replacement intervals: Specific replacement intervals must be considered based on previous service life, government or industry recommendations, or when failures could result in unacceptable downtime, damage or injury risk.
