How does a Pneumatic Actuator Work?

Pneumatic Actuator A pneumatic actuator sits on top of a control valve and opens and closes the valve. Oil and gas producers use pneumatic actuators and control valves to control processes ranging from back pressure regulation to pressure reduction to liquid level control. How a Pneumatic Actuator Works A pneumatic actuator is one component of

Use of a Positioner for a Control Valve

A Positioner for a Control Valve A positioner for a control valve is used to adjust a valve’s position based on a desired setpoint for a process variable, whether it be pressure, temperature, or flow. Types of valve positioners include pneumatic, electro-pneumatic, and digital. In this post, we’ll look at the basics of valve positioners and an

Kimray Pneumatic Level Controllers

How does a Pneumatic Level Controller Work?

Pneumatic Level Controller A pneumatic level controller works with a pneumatic control valve to provide liquid level control in oil and gas production. Producers typically employ these controllers on production vessels like horizontal and vertical three-phase separators. Some also use them on two-phase separators, glycol dehydration systems, and free water knockouts. How a Pneumatic Level Controller

Vapor Recovery Unit in the DJ Basin Using Electric Pilot

A producer in the Colorado DJ Basin was using a pneumatic controller for an inlet suction control valve on a vapor recovery unit (VRU). Vapor recovery is a common practice in Colorado, and electric control products are becoming more common because of the strict emissions regulations there. In light of these needs, we asked the
