Hand operated flat valve

VALVE BODY Working Pressure 2000 Psi ~ 15,000 Psi Nominal Bore 1-3/16" ~ 9" (46 mm ~ 230 mm) Working Temperature -60°C ~ 121°C (KU grade) Material Classes AA, BB, CC, DD, EE, FF, HH Specification Levels PSL1 ~ PSL4 Performance Levels PR1 ~ PR2 Structural Types  FC type, FLS type Structural Features & Advantages · Full Bore Design: Effectively eliminates pressure drop and eddy currents, reducing erosion of valve components by solid particles in the fluid. · Post-Sealing (Behind-the-Seat Sealing): Greatly reduces operating torque during opening/closing. · HVOF-Sprayed Hard Alloy Sealing Surfaces: Valve seats and discs are coated with high-velocity oxygen fuel (HVOF) sprayed hard alloy, providing excellent wear and corrosion resistance. · Back Sealing Structure on Valve Stem: Enables replacement of stem packing under pressure for convenient maintenance. · Hydraulic Drive with Emergency Handwheel: · Primary hydraulic actuation for hig…
