GWS Supply/Duncan Company can help you with your Butterfly Valve needs from Resilient Seated Butterfly Valves to High Performance and anything in between such as Damper Valves or Sanitary Butterfly Valves we have it all.
Having trouble finding a valve in stock for quick delivery? Contact us at GWS Supply/Duncan Company and our inside technical staff can help solve your problems.
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
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.

Comments Off on Aseptic Samplers for Food Production with Sentry
In the food industry, aseptic equipment is vital to ensure food safety. That equipment includes aseptic samplers used by quality control personnel to easily and safely sample liquids from closed systems such as food and beverage process lines and vessels. Aseptic samplers guide the product through a hermetically sealed system directly into a bottle without contact to the environment.
What is Aseptic?
The definition of aseptic is “free from the living germs of disease, fermentation, or putrefaction or protection against pathogenic microorganisms.” Aseptic sampling equipment is used in food processing to reduce the likelihood of contamination from harmful pathogens mainly from microorganisms, during sampling.
Contamination risk in food production comes from using incorrect samplers or using samplers incorrectly. Therefore it’s critical to choose the right aseptic sampler to prevent contamination and ensure food safety.
Design Determines Effectiveness
Aseptic sampler selection starts with the design, which determines the sampler’s effectiveness in preventing contamination as well as ease of use. An aseptic sampler consists of the body, an actuator and a stem with a sealing element that seals at the process connection.
The sealing element, which is either a diaphragm or a bellows, is a critical part of the sampler, especially the material of construction. Seals made of softer material such as ethylene propylene diene monomer (EPDM) can move over the complete area of the seal. This can cause dead spaces and infiltration of the seal by the food product which leads to contamination.
The best aseptic samplers use a bellows made of polytetrafluoroethylene (PTFE) as the sealing element. The PTFE bellows has many advantages. The PTFE’s slippery surface guarantees an optimum cleanability as no product can stick to the bellows. Another reason is the elasticity. The PTFE bellows is only moving at one point, the fold itself. Superior to common metal bellows design, the low-adhesive, long-life PTFE bellows provides one-piece sealing that’s resistant to nearly any product. The cost of replacement of a PTFE bellows is considerably less compared to a metal bellows. Also, PTFE bellows can be changed without special tools to simplify maintenance and reduce downtime.
Select a No Dead Space Design
The design of the sampler body is important to preventing contamination, too. It affects how well the sampler seals, drains and cleans via clean-in-place (CIP) and sterilization-in-place (SIP) methods. The body of a sampler with a one-piece, dead space free design made from a solid billet of 316L stainless steel provides hermetic sealing against the environment in combination with the PTFE bellows to eliminate process contamination.
The dead space is where food debris can collect and contaminate the process. The lack of dead space also makes the sampler drain completely and easier to clean. A dead space free design also allows food products to flow gently through the sampler to preserve the product sample quality.
Following the selection guidance above can help you select the best aseptic sampler for your food production application to avoid contamination and ensure food safety.

YTC Positioners lead the way in tough applications.
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.

Comments Off on 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.

Comments Off on BT6-B Balanced Pressure Thermostatic Trap for Clean Steam
Is your clean steam process getting to the temperature you require? If not, you may be experiencing condensate back-up or air binding.
If this is the case, it would be prudent to ensure that the steam trap is suitable for the application. Though clean steam thermodynamic steam traps are suitable for drip applications, a balanced pressure thermostatic trap, constructed of 316L, should be used for process applications. The balanced pressure thermodynamic steam trap should contain a minimum sub cooled element, be installed to allow for full drainage, contain an un-insulated drip leg of no less than 12″* and be fully open when cold. In the unlikely event that these can’t be met, traps can be provided with a fixed bleed.
*Please note that the length of the drip leg may be able to be adjusted depending on the load. The length of the drip leg in light load applications may be shortened, provided that appropriate calculations are made.
