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.
APV and it’s resellers refuse any liability for damage to people, property or plant as well as loss of production and loss of income under any circumstances but especially if caused by: Incorrect installation or utilisation of the valve or if the valve installed is not fit for the intended purpose.

API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES DURING OPERATION BEAR IN MIND THE FOLLOWING WARNINGS: a- The graphoil packing and body gasket is very brittle: any twisting or bending shall be avoided. b- The internal parts of valves (gate, stem, seats) shall be handled with care avoiding scratches or surface damage.
API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES • The protection must be restored following the instruction indicated from APV in accordance with the painting cycle used. • Without any gate 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.
API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES APV expanding gate valves in liquid service must be equipped with a thermal relief system (if the thermal relief system utilises needle valves, they must be in the OPEN position prior to the valve operation). Failure to do so may result in catastrophic malfunction.
Page 10
CORRECT INCORRECT INCORRECT f- APV’s preference is that through conduit gate valves be installed in the vertical direction. The horizontal orientation is acceptable as shown below. It may be necessary to adequately support valve actuation in order to protect the valve and/or actuator from improper weight distribution and excess stress.
API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES To prevent damage to the valve, APV recommends first installing a spool piece instead of the valve whilst flushing the pipeline. If a spool piece is not an option, install strainers at critical locations upstream from the location to remove foreign debris.
Page 12
Repeat the operation every 6 months if the pipeline is not used. d- Always get authorisation to partially operate an in-service valve. Personal injury may result from sudden release of any process pressure. APV recommends the use of protective clothing, gloves and eyewear when performing any installation or maintenance.
Page 13
After commissioning, once you believe the service is clean you can inject a suitable grease line flushing agent and then partially stroke the valve again. You should consult a valve maintenance specialist as different service, media, pressures and temperatures, etc., can require totally different practises. APV recommends the following programme for start up: - 1.

The following inspection and maintenance procedures of valve components should be performed by a professional valve repairer. Replace any parts that are damaged with genuine APV spare parts.

Clockwise rotate the handwheel to CLOSE the valve, rotate counter-clockwise to OPEN the valve. e- When operating a gate valve, APV does not recommend the use of any leverage tool opening or closing the valve. Carefully observe the position of indicator during operation. When the position indicator shows OPEN or CLOSED, rotate the handwheel in the opposite direction one half turn to release the pressure between the stem and drive nut.
Page 18
Return the gate to either the full OPEN or full CLOSED position and inject an additional amount of lubricant to complete the process. e- APV recommends for buried valves, a minimum of 4 cups of lubricant per valve once extended lines are filled.

API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES 8.2.3 Stem Seal/ Packing Maintenance a- In the event of stem packing leakage, CLOSE the valve and release the cavity pressure. b- Remove the stinger from the packing injection fitting. Insert the pressure relieving stinger tool to relieve any stem packing pressure.

Incorrect TRAVEL LIMIT and TORQUE LIMIT settings can result in catastrophic valve failure! Important: APV recommends that all actuation is installed and calibrated in a controlled testing environment. Utilise a hydro-test to simulate the targeted operating conditions while setting TRAVEL LIMITS and TORQUE LIMITS.
API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES If actuation is to be installed after shipment from APV, IT IS CRITICAL THAT THE SLAB DOES NOT DROP TO THE BOTTOM OF THE VALVE DURING ACTUATION INSTALLATION! THIS MAY RESULT IN SEAT DAMAGE.

API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES Use extreme caution when venting the body cavity of a pressurised valve. If the body cavity keeps venting fluid at a constant flow rate for a very long time, it is a signal of bad sealing of the valve seats. For liquid service only a lower drain valve will immediately indicate a leak.
Page 23
API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES DIAGRAM 1 Thermal relief system with bonnet vent f- Once venting is complete, CLOSE fitting (‘B’ below) tightly, then operate the valve to the OPEN position and OPEN valve ‘A’ to allow the thermal relief system to operate as designed. 8.5.2 Draining procedure The purpose of draining the body cavity is to bleed out all the liquid collected in the body cavity.
Page 24
8.6 EMERGENCY STEM SEAL PLASTIC PACKING INJECTION APV Expanding Gate Valves are equipped with a packing fitting usually having a ball check as illustrated in Figure 3. In the event of damage to the stem packing which causes a leak, plastic stick packing can be injected into the packing box to increase packing box pressure and eliminate the leakage.
