Water
Water valve and orifice calculators
Size water control valves and estimate what a valve or orifice will pass.
Cv & Kvs Values
Calculate the Cv and Kv needed to pass a water flow at a given pressure drop.
Water Flow Rate through a Valve
Calculate water flow through a valve of known Kv.
Water Flow Rate through an Orifice
Calculate water flow through an orifice.
Results are preliminary engineering estimates based on the stated methods and your inputs. Have a qualified engineer verify them before design, procurement or safety decisions. Need a reviewed design? See our steam system engineering services or talk to our engineers.
