M3The M3 is a 3” nominal MOVthat’s used worldwide in applicationswhere high flow capacity isrequired. It is used primarily insurface wellhead and productionapplications. Like all MOVs, the M3is easily actuated and is generallyconsidered the smallest MOV effectivelyused with the S-15,000stepping actuator.SD24733M3 Parts ListKey No. Description Quantity Standard Material1 Body 1 Alloy Steel2 Outlet Flange Assembly 1 Alloy Steel3 Front Disc Assembly* 1 Ceramic/S.S. or Tungsten Carbide/S.S.4 Back Disc Assembly* 1 Ceramic/S.S. or Tungsten Carbide/S.S.5 Calibration Band* 1 Stainless Steel6 Turning Fork 1 Alloy Steel7 Bonnet 1 Alloy Steel8 Capscrew 8 Alloy9 Capscrew 8 Alloy10 Dowel Pin* 7 Stainless Steel11 Gear Operator, Handwheel 1 Alloy Steel12 Thrust Bearing 1 Delrin13 Spacer Ring 1 Alloy Steel14 Gear Operator Adapter 1 Alloy Steel15 Drive Shaft Assembly 1 Alloy Steel16 Indicator Head 1 Alloy Steel17 Sheet Metal Screw* 2 Alloy Steel18 Capscrew 2 High Strength Alloy19 Capscrew 8 High Strength Alloy21 Shaft Bushing 1 Turcite-A22 Key 1 High Strength Alloy24 O-Ring, Turning Fork* 1 Viton25 O-Ring, Turning Fork* 2 Viton26 O-Ring, Outlet Spool* 1 Viton27 O-Ring, Outlet Spool* 2 Viton28 O-Ring, Bonnet* 1 Viton29 O-Ring, Bonnet* 1 Viton30 O-Ring, Bonnet* 1 Buna-N31 O-Ring, Back Disc Assembly* 1 Viton32 Back-Up Ring* 3 Teflon33 Flat Washer 2 Alloy Steel34 Drive Screw 4 Stainless Steel35 Valve I.D.
