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.


Donaldson can provide Compressor Filtration Solutions

Donaldson Company is one of the leading suppliers of filtration solutions.

Synteq XP Air-Oil Separator Media   –   Donaldson developed a unique, patented coalescing media exclusively for use in premium air-oil separators.  Simply put, this advanced media delivers lower restriction, superior draining, and longer life than the “off the shelf” media types used by most suppliers.  Replacing your current AOS element with a Synteq XP element will result in lower restriction and increased compressor output.

Air Oil Separation   –  Donaldson uses advanced design tools to engineer air-oil separators uniquely for each customer based on your project goals.  Whether you want to minimize separator pressure drop to make your compressor more energy efficient or limit oil carryover to reduce your maintenance cost.

Inlet Air Filtration – Donaldson invented the engine air cleaner and has led the world in air filtration technology.  We are constantly working to deliver new, more efficient, less costly and smaller air cleaner designs.  For the compressor market, we have designs to handle every flow range and environmental challenge.

Lubrication Filtration  –  Donaldson currently uses 35 different grades of media to tailor lube filter designs to your unique oils, contaminants and element life requirements.

V-Ball Control Valve Packages

YTC Positioners lead the way in tough applications.

for more information contact us at Duncan Co

Process industries often depend on high performance valve actuation in harsh environments.  Despite the difficult surroundings, process plants demand the latest technology, such as smart positioners, which allow technicians to use auto-calibration and simple diagnostics to commission and monitor their entire system at the push of a button.  In many cases, the valve, actuator and smart positioner package is exposed to extreme temperatures, dirty conditions and other challenges such as high vibration.

What to know about Drip Pots and Corrosion Monitoring

Internal metal corrosion in hazardous liquid, gas transmission and gas-gathering applications is inevitable and continues to cause leaks and catastrophic failures.  Due to the fact that internal corrosion is time dependent, the number of incidents could be increasing due to aging pipeline infrastructure.  Such disasters can damage the environment and cause costly downtime and waste in pipeline productivity, in addition to astronomical cleanup costs.
