Process valves – the basics

What are the two types of valves used?

The two specific types of valves, rotary and linear.

The rotary valve makes use of rotary motion for the flow of liquid.

Linear valves make use of either pneumatic/electro-magnetic force or by the rotation of a threaded rod (stem).

What are the types of control valves?

  • Directional Poppet Type Valves
  • Directional Solenoid Valves
  • Flow Control
  • Directional Control Valves – Proportional
  • Ball Valves
  • Butterfly Valves
  • Electric Actuators
  • Pneumatic Actuators
  • Pneumatically Actuated Valves
  • 2/2 Solenoid Valves

What is a process valve?

Process control valves are used in controlling variables such as liquid level or flow, temperatures or even pressure in industrial applications.

Liquid can go through the valve as required (at a controlled variable), automatically opening and shutting it, according to system demands.

Pressure controlling valves are ideal for the control of pressure within the system, whereas temperature controlling valves are used to maintain a stable system temperature.

What is a valve and its function?

Valves are used to control the temperature, flow, pressure or level liquid in a system, ensuring that the system is functioning optimally or as expected.

Valves also help prevent the backward flow of liquids in a system, which could cause damage or a fault (and result in downtime).
