Compressed air valve and orifice calculators

Cv & Kvs Values

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

Air Flow Rate through a Valve

Calculate air flow through a valve of known Kv.

Air Flow Rate through an Orifice

Calculate air flow through an orifice or leak of known size.

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.
