Do not “cheat”. TO OPEN THE VALVE, rotate the handwheel counter-clock- wise until the gate stops at the bonnet TO CLOSE THE VALVE, rotate the handwheel clockwise until the gate stops at the bottom. OVERVIEW MODEL M/HM & FC GATE VALVE OVERVIEW APV API6A GateValves are integral body, bi-directional, parallel sided gate valves that are available in solid slab with a floating seat (Model FC) where the sealing force supplied by line pressure, or in expanding self energised slab (Model R). The Type ‘M’,‘HM’ and ‘FC’ GateValves are proven designs that have been standard in the oil field for more than forty years. Because of APV’s commitment to quality and the reliability of these standard designs, these valves can be maintained anywhere in the world, even in the most remote locations, without having to procure hard to find parts. Available from 1-13/16” to 7-1/16” and from 2,000 psi to 15,000 PSI working pressures. FEATURES AND BENEFITS MINIMAL TORQUE: Upper and lower bearings are used to minimize operating stem torque and are isolated from well fluids to increase durability. BI-DIRECTIONAL SEALS: The one piece, parallel sided (Model FC) slab gate seals on a floating seat. The sealing force is supplied by line pressure. The expanding type self energised slab (Model M/HM) seals on both seats. METAL TO METAL STEM BACK SEAT: The gate stem has a bevelled shoulder which allows for metal-to-metal sealing to the bonnet seat. FULL THROUGH CONDUIT: The full through conduit I.D. provides smooth flow with minimal turbulence as well as providing an unobstructed passage for well intervention tools. REPLACEABLE GATE AND SEATS: Gate and seats are field-replaceable. RE-ENERGIZEABLE STEM PACKING: The Stem Packing can be re-energized by injection plastic sealant in between the packing stacks. STEM PACKING REPLACEABLE WITH VALVE UNDER PRESSURE: The bonnet stem to back-seat seal allows the stem packing to be replaced with the valve under pressure. GREASE FITTING The valve body may be greased through the fitting provided in the valve Bonnet. 11 API6A GATE VALVES PAGE 69
