Custom Specialty Selection Information

The Reliability Cycle

Reliability of an industrial process is determined by the control of variables within the process i.e. Flow, Pressure, and Temperature. Since the final control elements – the fingers in the sauce – are control valves, proper valve performance is critical to the reliability of the process.

Why do we use Control Valves?

As the number of components in series increases, the system’s reliability decreases. In order to achieve a high degree of system reliability, the individual component reliability has to be high as well – especially for systems with many components

How do we classify Control Valves?

In order to simplify the selection and specification of a device with such a broad definition, control valves are traditionally classified according to one or more of the following factors:


By Function

  • On/Off
  • Non-return
  • Final Control
  • Element


By Application

  • General Service
  • Special Service
  • Severe Service



By Motion

  • Linear
  • Rotary


Classifying Control Valves According to Service Application

General Service


General service valves are those designed for a majority of commonplace applications with lower pressure ratings


  • Lower ANSI Class: 150 to 600
  • Moderate Temperature: -50 to 650°F
  • Noncorrosive fluids
  • Minimal Pressure Drops
  • No cavitation
  • No flashing
  • Carbon or Stainless Steel
  • Interchangeable and common to a wide variety of applications

Special Service

Special service valves are custom-engineered and designed for a single application due to any of the following:


  • Higher pressures
  • Demanding temperatures
  • Corrosive fluids
  • Moderate Pressure Drops
  • Mild cavitation
  • Special materials requirements
  • Unique applications

Severe Service

Severe service valves are fitted with special features to handle extreme applications, such as high pressure drops that result in severe cavitation, flashing, choking, or high noise levels


  • All pressures
  • Extreme temperatures
  • Severe Pressure Drops
    – Cavitation
    – Flashing
    – Choking
    – Noise
  • Custom-engineered trims
