I assumed your k 1 was 340 ft (the largest value for globe or angle vales), that d 1 was 0.75 and d 2 was 2. Resistance coefficient k (use in formula hf = kv/2g) nominal pipe size fitting. Specific mass of fluid at p and t kg/m³. Source: www.millikenvalve.com

Bends would have k values of 8.2. Globe valves are well suited for applications requiring flow regulation. Source: armourvalve.com

This is a huge increase over the turbulent flow situation. K can be calculated from the valve coefficient c v using the following equation: Source: wikizero.com

The resistance coefficient k is considered to be constant for any defined valves or fittings in all flow conditions, as the head loss due to friction is minor compared to the head loss due to change in direction of flow, obstructions and sudden or gradual changes in. K v is the metric value of c v and is calculated as k v =c v x 0.85. Source: www.winstores.com.mm

Pressure drop through all pipe singularities of a pipe section (valve, fitting.) A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body.
