Valve Automation for Industrial Process Flow Control

Valve Automation

Industrial valves manage the flow through pipelines and processing equipment. The valve functions as a faucet, regulating the flow through the pipe by opening and closing it. Automating a valve involves installing some form of actuator and control system. Actuator power occurs by hand, electricity, pneumatics, or hydraulics. Valve automation is helpful for flow management in pipe systems that need precision control or fail-safe emergency cutoff. Improved flow control and throughput through automated valves help cost savings by reducing product waste. Automated valves have application in many industrial settings, including municipal water distribution, wastewater treatment plants, power plants, mines, chemical plants, food and beverage processing, refineries, and pipelines. 

Actuated valves support plant safety by allowing for consistent operating levels and assuring safe operation in situations where high temperatures, high pressure, harmful gases or vapors, flammable materials, or other circumstances might lead to catastrophic failures. Automatic valve actuators revert to their fail-safe settings in an emergency, preventing industrial accidents, environmental spills, equipment or building damage, and other disastrous results. Automation also provides remote access to valves that are difficult or impossible to reach, providing a means to return them to normal operation or a safe position. 


Handwheels, levers, and gears operators are examples of manual valve actuators. These are less expensive and more straightforward to implement than other options, but they require a human to open and close the valve, which isn't always practicable or desired. Larger valves need a great deal of force to operate manually, and some are in remote or hazardous areas. It might also pose a safety risk if the valve has to be closed fast. 

The power for pneumatic valve actuators comes from air pressure or another gas. The two most common types of pneumatic actuators are scotch yoke and rack and pinion designs. Pneumatic actuators have advantages because they require minimal maintenance and are well suited to temperature fluctuations. 

Like pneumatic actuators, hydraulic actuators convert fluid pressure into motion. Hydraulic fluids provide the motive power in this type of actuator. They provide torque more significant than those produced by a pneumatic actuator of the same size. In some instances, the process fluid may supply the hydraulic pressure. 

Electric actuators operate valves using an electric motor and gearing to produce torque. Electric actuators are quiet and energy-efficient. Because of their gearing, opening and closing times of electric actuators are relatively slow. As a result, they are not best suited for high-speed position-changing applications. 

In recent years, valve automation has made significant progress with the advent of application-specific standards, certifications, safety integrity levels (SIL), and digital protocols. 

Intelligent and digital valve positioners now contain a digital communication protocol and additional features. Device diagnostic advancements are significant because they allow the transition from traditional corrective and planned maintenance to predictive maintenance. Valve positioner diagnostics are increasingly advanced, enabling valve testing to determine if maintenance or replacement is required. 

Valve actuators are critical components in process automation. Valve automation allows businesses to continually improve process efficiency and product quality while protecting people, facilities, and the environment. The latest generation of valve automation technology enables industrial firms to conduct on-site diagnostics and better understand overall valve performance at a reduced cost. 

For optimum outcomes, automated valve applications must involve a knowledgeable and experienced valve specialist who can advise on the appropriate technology and critical installation practices. 


MSEC - Your Source for Pipeline Valves

Pipeline Valves

The petroleum and natural gas industries rely significantly on pipeline infrastructure for most of their operations, from refining to distribution. Pipeline infrastructure and reliable control systems are vital to the sector's success. Any systemic faults or gaps could result in significant losses, hazardous leaks, and even environmental catastrophes. 

Industrial valves play a critical role in the safe operation of oil and gas pipelines. They are responsible for flow regulation and ensuring the integrity of supply lines, among other essential functions. The following is a guide to the many industrial valves recommended for the oil and gas industry to grasp their functionality and applications better.

Globe Valves regulate and control the flow of liquid, many times in systems that require precise flow control. Additionally, they are suitable for shutoff but are typically more expensive than gate valves. 

Gate Valves are the most often encountered form of valve. They are used to initiate and terminate the flow of liquid. In actuality, these valves are either completely open or entirely closed. These are excellent shutdown valves. Gate valves are available in various styles to suit a variety of applications. 

Butterfly Valves halt or start the flow, as well as regulate it. These valves are tiny and lightweight, needing less space than valves performing similar functions. 

A Ball Valve is a quarter-turn valve utilized in shutoff applications. The valve controls the flow of fluid employing an integrated ball that rotates within the valve body. Ball valves are the industry standard for on-off applications because they are lighter and compact than gate valves. There are two primary designs: floating and trunnion (side or top entry)

Check Valves are responsible for preventing backflow in a pipeline system. When fluid flows through a line, it opens a check valve; however, when the flow reverses, the valve closes. 

Relief Valves are employed to safeguard a pipeline system from damage caused by high-pressure events or vacuums. The valves release the pressure to a preset point; therefore, it is not a full release of pipeline pressure. There are various types of relief valves for multiple applications.

Pinch valves are linear motion valves used for throttling and shutoff in piping systems that handle solids, slurries, and thick fluids. A pinch valve regulates the flow by the use of a pinch tube.

Needle Valves are similar in design to globe valves, with the primary distinction being the sharp needle that allows for precise flow control.

Our vast selection of pipeline, control, and safety valves are qualified for the most demanding oil and gas applications. 

Upstream involves the extraction of oil and natural gas from the ground; midstream is the safe movement and distribution of oil and gas: and downstream involves converting petroleum resources into fuels and finished products. Upstream, midstream, and downstream segments of the oil and gas industry require robust and reliable valves. 

The oil and gas industry valve service and operating conditions are unique and harsh. Environmental and mechanical conditions can adversely affect the life of a valve. Remote installations expose valves to severe temperatures and pressures - from deep-sea to desert pipelines - these valves can be left open or closed for years without being cycled, yet it is critical they function reliably.

Buckling Pin Pressure Relief Devices

Buckling Pin Pressure Relief Devices

BS&B manufactures pressure relief devices (inline and angle discharge) with fast-acting/full opening buckling pins to protect personnel, equipment, and the environment from the dangers of overpressure. Buckling pin pressure relief devices combine the accuracy of rupture disks with the ability to be 'field- reset' while still installed following an overpressure event. 


Operating Pressure Ratio

Buckling pin technology is highly resistant to operating pressure conditions. The BPRV runs at up to 95% of the minimum set pressure. This ratio is further settable with special testing.

Pressure Cycling Service

Buckling pin devices are well suited to cyclic service pressure conditions. When operating under compression, the buckling pin is not subject to tensile fatigue failure. The BPRV handles pressure cycles up to its maximum operating pressure ratio with negligible impact on service life.

Buckling pin devices are designed as a non-reclosing ‘reclosable’ pressure relief device. They are an alternative "non-reclosing" pressure relief device, usually rupture disks. Buckling pin devices are also an alternative to reclosing pressure relief valves , API series and pilot operated valves. They provide in-line pressure or vacuum relief, are easy to upgrade a rupture disk position, install directly between companion flanges, and offer quick and simple external reset, without opening flanges/piping.

BS&B Buckling Pin Features

Buckling pin pressure relief devices provide practical technology for the protection of applications containing one or more of the following conditions:

  • Continuous processing (fast reset in the line)
  • Hazardous service (limits operator exposure)
  • Large line size (convenient reset in the line)
  • High flow capacity
  • Inaccessible location (external reset in the line)
  • High operating pressure to set pressure ratio
  • Sizes from 1 inch to 60 inches
  • Cryogenic designs available
