Habonim Cryogenic Ball Valve with ABZ Spring Return Electric Actuator

We recently had a customer come to us to help resolve a current problem they were having with a competitor’s valve and actuator, they were having failure on multiple valve systems.

This application was for Natural Gas at a power station and they needed a heavy duty Spring Return Electric actuator for this cryogenic application.  Since our initial shipment, we have sold over 200 of these units.

Do you have an application giving you problems?  If so, contact us at the Duncan Company and ask how we can help get you the right valve for your application!

Quadbeam S20 Hygienic Suspended Solids Sensor can help Dairy Plants increase Yields & Efficiency!

Quadbeam Technologies S20 Hygienic Suspended Solids Sensor

Locating the exact point of transition between product and water or different products can be challenging with many plants relying solely on time and flow calculations.

A Quadbeam Sensor will quickly and accurately identify the interface time after time which could mean any or all of the following to your process:

  • Faster Change Times giving to reduced down time
  • Increased Yields
  • Decreased waste treatment
  • Decreased water consumption

With the use of a Quadbeam sensor you get to change at the actual point you want to, not a theoretical point.  Quadbeam’s four beam ration metric technology self compensates for change caused by contamination or sensor surface or aging of the instrument.

AUTOMATED XOMOX PFA LINED PLUG VALVE WITH PFA SEAT

Application:  Gypsum Slurry at a Generating Station

For corrosive applications, both the choice of lining material and the method of lining are critical considerations.

PFA lining material is melt-processible, meaning that this lining material can be locked to the valve body and plug using cast-in dovetail recesses and machined grooves.  (PTFE cannot be locked in.)

  • PFA Temperature range is rate to 400°F
  • Chemical inertness
  • Excellent permeation resistance
  • Low coefficient of friction
  • Toughness
  • Flexibility

Natural Gas Processing Solutions with Cascho Control Valves & Regulators

Model HP-1+6+S — most commonly applied to develop a constant differential pressure across a rotating shaft seal to provide proper sealing and lubricating conditions over varying pressure ranges.  *For gaseous and non-flashing, non-cavitating liquid services.

Ranger QCT  —  is a universal control valve that is applicable in most control valve applications, especially steam.  It provides longer life on difficult services where conventional ball or globe control valves have problems with body or trim wear.  It provides noise control for gaseous service, and cavitation and flashing control for liquid service.  It is able to withstand temporary distortions due to “thermal shock” without compromising continued control of the process.

Model 2296  —  is capable of handling air, gases, oils, water, oxygen, steam and many corrosive process fluids.  With optional construction it is suitable for cryogenic service.
