Manual Valve Vs Automated Valve

In today’s extremely automated industrial cleaning equipment depends heavily on valves remotely actuated either by a qualified operator or by an automated computerised control system. However performing predominantly the same function as manually operated valves, automated valves operated by electricity, air, hydraulics or some other means are considerably different than manual valves not only in… Continue Reading

A brief look at different control valves and their applications

  Control Valves In the processing industries, many valve types are used for process control. This article examines several different control valve types, their functions and positioners. The quarter-turn control ball valve’s design is commonly used to control liquids in throttling systems in which the direct control of flow rates working with pressure, temperature and… Continue Reading

Types of Actuators

Actuators are mechanical or electro-mechanical devices that provide controlled and limited movements or positioning which can be operated electrically, manually or by various fluids. The two basic motions are linear and rotary. The linear actuators can convert energy into the straight line motions. The positioning for the application have a push and pull function which… Continue Reading

Valve-Actuator Types

There are three types of actuators namely electric, pneumatic and hydraulic. The pneumatic valve actuators are powered by air and gas. The air pressure acts as a piston to create the linear force to close the open valve. The power plants have always used pneumatic actuators to drive the control valves throughout the facilities. The… Continue Reading

New developments in pneumatic valve

Pneumatics are widely used in packaging machines to drive the motion and he actuates machine sequences. It is reliable, compact and a lightweight technology that provides effective control and actuation to help with packaging machines and the designers create innovative systems that are unique while staying competitive. Pneumatic valve technology plays a big role in… Continue Reading

Valve Leakage

Leaking isolation valves are found in the steam generation industry and they are equally widespread in the detriment to the P&L statements worldwide. The thermal engines and steam plants are powered by different energies and the greater fuel efficiency. The valves maintain the separation by isolating the high energy processes from the low energy processes.… Continue Reading

Valve installation

Butterfly valves are designed for installation between the ANSI Class 125/150 flat or raised face flanges that are used to regulate the flow in a pipeline. Lined pipes, heavy wall pipes and flanges need to have a minimum allowable inside the diameter at the center body face to clear the disc sealing edge when opening… Continue Reading
