Fluids and Solids Handling

Valve Design Reduces Contamination in Hygienic Operations

images

The modular Unique Mixproof 3-Body valve safely provides reliable fluid handling, making it suitable for use as a changeover valve in hygienic industries such as food, dairy, beverage, and personal care. It can replace two or more valves because it is constructed with two independent valve plugs, which enables two different fluids to pass through the same valve without mixing, even in the event of pressure shock. The double-seat design avoids cross-contamination while the double-lip seals ensure spillage-free operation. It is easy to maintain and clean and the top-loaded design has no adjustable components, contains a maintenance-friendly actuator, and has built-in leak-detection on all seals. It is simple to configure and upgrade and the seat-lift and seat-push function meets stringent hygienic standards.

Screw Pump Design Lowers Power Consumption

images

The ULVAC LS dry screw pumps can serve as compact, lightweight replacements for multistage dry Roots pumps and are easy to retrofit into existing vacuum applications. They are compact and have low power consumption at four pumping speeds ranging from 120 m3/hr to 1,000 m3/hr. Each pump in the series features a pair of conical-shaped, variable-pitch steel screws that allow the pump to be one-third the length and one-third lighter than other screw pumps that have similar pumping speeds. This screw design allows faster pumping speeds near atmospheric pressure using less power than a conventional pump. Maximum power consumption is 0.6 kW upon reaching the maximum-rated pressure. A specialized built-in silencer maintains the noise level below 61 dBA.

Valve Trim Reduces Cavitation-Induced Vibration

images

Vee-Ball rotary control valves (Models V150, V200, and V300) are now available with Cavitrol Hex anti-cavitation trim to reduce or eliminate vibration caused by cavitation. Cavitation is the formation and collapse of vapor bubbles (cavities) in liquid flow streams produced by changes in pressure and velocity. Vibrations can damage a valve such that it loses the ability to control flow properly; when left unchecked, damaged valves can create unsafe working conditions. The anti-cavitation trim option is available on Vee-Ball valves in nominal pipe size (NPS) 4–12 for gas, steam, and liquids. To meet specific application requirements, a variety of metal and soft ball-seal materials are available. The trim can also be easily retrofitted into previously installed Vee-Ball valves after minimal modifications to the valve body. Cavitrol Hex does not affect valve shutoff or valve temperature limits, and does not influence the primary ball/seal interface.

Panel Attachment Reduces Explosion Damage

images

TARGO-VENT is an opening angle limiter for use with REMBE Explosion Panels, which relieve explosions by bursting at a predetermined pressure point at a location in which there is no danger to the adjoining infrastructure. The TARGO-VENT attachment diverts shock waves and flames of an explosion in a controlled manner (at a defined angle of approximately 30–45 deg. upward or to the side), effectively reducing the size of the required safety area in front of the panel or vent opening. The limiter is made in standard explosion panel sizes, and can easily be retrofitted onto existing REMBE explosion panels. It is made of stainless steel and, in combination with REMBE explosion panels, is type-tested in accordance with the ATEX Directive 94/9/EC (ATEX 114). TARGO-VENT is authorized in accordance with FSA 13 ATEX 1637, and adheres to National Fire Protection Association (NFPA) standards.

Valves Control Water Temperature in Eyewash Stations

images

The first moments after exposure to a hazardous substance or chemical are critical. Emergency eyewash stations and showers allow workers to flush away substances that can cause injury. However, flushing water that is too hot or too cold can intensify injuries, rather than mitigating them. Water below 60°F can cause hypothermic shock and water above 100°F can increase chemical reactions and irritations. Tepid water (between 60°F and 100°F) helps personnel keep the chemical burn or exposed area in the water stream for the recommended 15-min flushing period. Safe-T-Zone thermostatic mixing valves (TMVs) regulate water temperature whenever an eyewash or emergency shower is activated, making tepid water easily available. The water temperature can be preset to an adjustable setpoint. Three models are available depending on capacity requirements, allowing for flowrates from 9.7 gpm to 62.5 gpm. All models have a solid brass, lead-free construction. The valves can be installed in available stainless steel flush or surface-mount cabinets. They can be configured in either a top- or bottom-inlet position, depending on the supply water location. These valves are compatible with most existing eyewash systems, including Optimus, Eyesaver, and Speakman Traditional Series 400 and 500. They are certified to meet American National Standards Institute (ANSI), International Safety Equipment Association (ISEA), American Society of Safety Professionals (ASSP), Compliance, Safety, Accountability (CSA), and NSF standards, such as ANSI/ISEA Z358.1, ASSE 1071, CSA B125.3 and NSF/ANSI 372.
