Cam lift and timing can put the valves dangerously close to the piston. We show you how to check the clearance In all but most the mild engine builds, taking extra time to check piston to valve ...

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...
