Steam valve and orifice calculators

Cv & Kvs Values

Calculate the Cv and Kv needed to pass a steam flow at a given pressure drop.

Steam Flow Rate through a Valve

Calculate steam flow through a valve of known Kv.

Steam Flow Rate through an Orifice

Calculate steam flow through an orifice, which also helps estimate leak losses.

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.
