Page 4: Introduction
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. - Page 5 EXPANDING SEAL PLUG VALVE DOUBLE BLOCK & BLEED API6D - TWIN SERIES MODEL TWIN EXPANDING SEAL PLUG VALVE NON LUBRICATED DOUBLE BLOCK AND BLEED DOUBLE BLOCK AND BLEED SOLUTIONS • Permanent integral thermal relief and bleed function • In-line mainternance in case of seal replacement •...

& repainting. • The protection must be restored following the instruction indicated from APV in accordance with the painting cycle used. • Without any ball movement, the internal surface of the valves must be inspected to check the complete absence of dust, rust, foreign matters and the integrity of lubricant coat. -
Page 11: Installation
APV DB&B expanding plug valve may be installed in any position. Flow direction The APV plug valve design is bi-directional. Flow shut-off is achieved equally on both sides of the plug in-dependent of flow direction. Note: The use of a Differential Thermal Relief (DTR) does result in a preferred flow direction. -
Page 12: Maintenance Prior To Flushing
EXPANDING SEAL PLUG VALVE DOUBLE BLOCK & BLEED API6D - TWIN SERIES f- Plug valves are usually bi-directional, and therefore may be installed in either direction. In some cases, ball valves such as ‘metal to metal’ and low temperature valves may be unidirectional, in which case the direction of flow will be indicated on the valve body. - Page 13 EXPANDING SEAL PLUG VALVE DOUBLE BLOCK & BLEED API6D - TWIN SERIES breakdown or shearing of the gel structure under high pressure injection and under the pressure between seating surfaces.

For maximum upstream sealing, it is important to torque the valve closed. he small APV plug valves are handwheel operated, and require up to 3 turns to open or close. Up to 2 turns expand or retract the slips, while turn rotates the plug. -

(pressure) thermal relief (DTR) bleed system. Background When APV valve is seated and completely fill with a liquid, any slight variation in temperature due to the sun’s rays or ambient thermal fluctuations will cause drastic changes in body cavity pressure resulting from thermal expansion. - Page 17 EXPANDING SEAL PLUG VALVE DOUBLE BLOCK & BLEED API6D - TWIN SERIES A manual body bleed valve is included on the APV as standard. This bleed valve installed in the relief system is opened after the APV valve is closed. Seal effectiveness can be immediately evaluated, after allowing a few seconds for stabilisation of cavity volume due to entrained air or gas.

To replace seating slips, the line must be drained. Place valve in open position (check body bleed for zero line pressure); then remove lower plate (No. 16) or bonnet (No. 8. APV has both top and bottom entry to facilitate in-line maintenance. - Page 21 APV valves with this self-contained thermal relief assembly should be installed with the discharge of the thermal relief valve piped to the upstream side of the valve. If, after the APV valve is installed in the line, it is noticed that the thermal relief assembly is piped to the downstream port, the tubing should be switched to the upstream port.
