API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES Australian Pipeline Valve - Installation, Operation and Maintenance Manual 3 I N T R O D U C T I O N The majority of this information is common knowledge to experienced steel valve users. When properly installed in applications for which they were designed, APV valves will give long trouble free service. This instruction is only a guide for installation, operation and minor maintenance. A professional APV approved valve engineering facility should be utilised for reconditioning and minor repairs. RESPONSIBILITY FOR VALVE APPLICATION The User is responsible for ordering the correct valves. APV Valves are to be installed in the observance of the pressure rating and design temperature. Prior to installation, the valves and nameplates should be checked for proper identification to be sure the valve is of the proper type, material and is of a suitable pressure class and temperature limit to satisfy the applications requirements. RECEIVING INSPECTION AND HANDLING Valves should be inspected upon receipt to determine: - Compliance to purchase order requirements. - Correct type, pressure class, size, body and trim materials and end connections (this information may be found on the nameplate or may be stamped on the body of the valve). - Any damaged caused during shipping and handling to end connections, hand wheel or stem. Note We do recommend that this entire document be read prior to proceeding with any installation or repair. Australian Pipeline Valve and it’s parent company take no responsibility for damage or injury to people, property or equipment. It is the sole responsibility of the user to ensure only specially trained valve repair experts perform repairs under the supervision of a qualified supervisor. Do not use any valve in applications where either the pressure or temperature is higher than the allowable working values. Also valves should not be used in service media if not compatible with the valve material of construction, as this will cause chemical attacks. The End User is advised that misapplication of the valve may result in injuries or property damage. A selection consistent with the particular performance requirements is important for proper application and is the sole responsibility of the end user.
