Industrial process control applications can present stringent and challenging performance requirements for the physical equipment and components that comprise the process chain. The valves employed in fluid based operations need to be resistant to the impact of extreme fluid conditions, requiring careful design and selection consideration to assure proper performance and safety levels are maintained in a predictable way.

Industrial valves intended for extreme applications are generally referred to as severe service or high performance valves. While there are plenty of published and accepted standards for industrial valves, one does not exist to precisely define what constitutes a severe service valve.

So, how do you know when to focus valve selection activities on severe service or high performance valves, as opposed to those rated for general purpose? There are a number of basic criteria that might point you in that direction:

  • Extreme media or environmental temperature or pressure
  • High pressure drop operation that may cause cavitation
  • Rapid or extreme changes to inlet pressure
  • Certain types or amounts of solids contained in the fluid
  • Corrosive media

Certainly, any of these criteria might be found in an application serviceable by a general purpose valve, but their presence should be an indicator that a closer assessment of the fluid conditions and commensurate valve requirements is in order. The key element for a process stakeholder is to recognize when conditions are contemplated that can exceed the capabilities of a general purpose valve, leading to premature failure in control performance or catastrophic failure that produces an unsafe condition. Once the possibility of an extreme or challenging condition is identified, a careful analysis of the range of operating conditions will reveal the valve performance requirements.

There are numerous manufacturers of severe service or high performance valves, each with specialized product offerings focusing on a particular performance niche. ABZ Valve manufactures high performance butterfly valves ranging from 2-48 inches and 150-600 psi. The valve design is ideal for manual or automated actuation, installed with a manual hand gear, electric actuator, or a pneumatic actuator. Seats are available as soft, metal, and fire safe, and body types include wafer, double flanged, and butt-welded. Construction materials include carbon steel and 316 stainless steel. A range of options and variants are available to customize the valve build to suit a replacement or new installation.

More information about the ABZ Valve high performance offering is included below. You can always get more information and discuss your special requirements with a valve specialist. They have application experience and access to technical resources that can help with selecting the right valve components to meet your severe service and high performance applications.

A Proven Ultrasonic Level Transmitter for Environmental, Water/Wastewater, and Energy Management Industries

SIEMENS SITRANS LU150
Reliable level control for
environmental applications
SITRANS LU150/180
The SIEMENS SITRANS LU150 is a short-range general purpose, 2 wire, 4 to 20 mA loop powered transmitter ideal for liquids, slurries, and bulk materials in open or closed vessels to 5 m (16.4 ft). The SITRANS LU180 is the intrinsically safe model.

Designed primarily for liquid applications in the environmental, water/wastewater, and energy management industries, the device is ideal for non-contact continuous level measurement of liquids and slurries in open or closed vessels.

The reliability of the level readings are based on Sonic Intelligence echo processing algorithms that Siemens has been refining for decades. These algorithms differentiate the true material level echoes from the false ones that can result from acoustic or electrical noises, as well as from agitator blades in motion. It's effective, accurate, unique, and it's exclusively Siemens.

Key Applications

  • Filter beds
  • Mud pits
  • Liquid storage vessels 
  • Food applications
