Frequently Asked Questions

What is Cf ?

Critical Flow Factor (Cf) A coefficient that defines how the pressure will recover after it drops to its lowest point (the vena contracta) inside the valve.  Each valve has one Cf, and it doesn’t change due to % open, like the Cv does.  Cf is a factor that is needed in order to calculate Cv

What is Cv ?

Valve Flow Coefficient (Cv) Cv is a valve’s capacity for a liquid or gas to flow through it.  Basically, the larger the opening in a valve, the larger the Cv.  As a valve is opened more and more, the Cv increases until the valve is fully open, where it reaches its highest possible Cv, or

What is the Valve Failure Position?

Despite how it sounds, “valve failure” does not mean that the valve itself has failed. In the event of power loss, electric actuators will cause their control valves to “fail,” or stop, in one of three positions—open, closed, or in place. Today we will look at what these three options mean. The term “power” here

Which Electric Actuator is Right for Me?

At the core of the oil industry’s move toward digital, low-emissions operations is the process of control—valves and valve actuation. In our effort to increase our automated, zero-emissions solutions, Kimray is offering two electric actuators, both effective, and both distinct. In this piece we’ll look at some specific features and typical applications of the Tritex

Why is Delrin a good material for corrosive environments?

Answer: Delrin is a thermoplastic that’s one of several formulations of polyoxymethylene. The material was invented in the 1950s, and it’s been used since then in all types ways: everything from yo-yos to guitar picks. The qualities that make Delrin so universal also make it a good fit for oil and gas production, especially severe
