The Best of Industrial Valves & Pressure Gauges 101
Valves are an integral part of the day-to-day functions- plumbing valves used in taps for hot and cold water, gas control valves on cookers and barbecues, small valves fitted to washing machines and dishwashers, and safety devices fitted to hot water systems.
Valve is a device that regulates the flow of gases, fluidized solids, slurries or liquids by opening, closing or partially obstructing various passageways. Industrial Valves are used in a variety of commercial, residential, military applications, and also in transportation. Oil and gas, power generation, mining, water reticulation, sewerage and chemical manufacturing constitute the majority of valves used by industry. These may be operated manually, or automatically, driven by changes in pressure, temperature or flow. Based on the varying needs, valves may be of different types.
- A check valve allows fluid to flow through it in only one direction. Check valves are two-port valves, that is, they have two openings in the body, one for fluid to enter and the other for fluid to leave.
-
Ball Valves are principally designed as on/off isolation valves for a wide range of temperatures and pressures; they have inherent quick opening flow characteristics. Specially designed ball valves however, may offer good flow control capabilities at high pressure.
-
Butterfly valves are for quick turn on or shut off applications including agricultural and irrigation, water distribution and waste treatment. Industrial applications including chemical, paper and pulp, and a wide array of industrial mediums.
-
Gate valve are commonly used in many garden, irrigation, and industrial flow control systems.
There are a wide range of industrial applications in which Pressure Gauges are utilized. Pressure Gauges are designed to measure the pressure of a gas or liquid. These instruments monitor and indicate the internal pressure and/or vacuum of vessels and systems, especially those having dynamic working characteristics that require regular monitoring. These vary in style, size, pressure ranges, and wetted parts material, depending on the application. Specialty tanks, such as fire extinguishers and medical gas cylinders use pressure gauges. The important types include:
-
Liquid Filled Pressure Gauges can be filled with various fluids, such as silicone oil, mineral oil and glycerin. The liquid filling provides protection to internal components of the gauge in severe environments in which the gauge may endure excessive vibration and pulsation. Gauges made of stainless steel can be used in corrosive environments or in applications that have strict sanitary requirements and are capable of withstanding high pressure cleaning.
-
Industrial Pressure Gauges have heavy-duty sensing elements and case designs and higher accuracy requirements than general purpose utility gauges, and are built for extended life, designed for harsh, corrosive environments.

Mazda Cx-7 to Hear British Accent in 3rd Quarter
The Mazda CX-7 sports crossover SUV will hear the British accent as it enters the UK showrooms in September. In order to adapt to the European taste, it has especially built characteristics following a drive test and program tuning carried out by Mazda’s European R & D Centre (MRE) that is based in Oberusel, near Frankfurt, Germany.
Prior to this, the CX-7 was successfully launched in both North America and Japan, where over 46,000 vehicles have been sold. It was appraised and then tuned by the MRE for driving performance and craftsmanship.
Almost 30 percent of the set up of the European Mazda CX-7 is different to other global versions. Tuning to handling, ride comfort, suspension settings, steering and brakes, ABS, ESP and NVH for power train, road noise and window noise are some of the improvements for the European market.
The company has also a specialized team that makes sure every model complies with European specifications, regulations, market needs and preferences. And this is found near Mazda's European design studio the R & D Centre. An engineering team composed of 15 persons took the US version of the Mazda CX-7 as their basis. Consequently, they developed the different specifications needed in order to fit the European customer preferences.
This started when the best performers in the European competition were gauged on the roads of the continent. Mazda Japan, the suppliers and the team all worked hard together for the European CX-7 to yield a driving experience that takes a more sporty direction. They did this by testing the car on Nürburgring’s Nordschleife, mountain roads, on German express ways at high speed. The CX-7 has also endured the winter testing in Northern Europe.
Mazda CX-7’s power train is a high-performance 2.3 litre DISI turbo petrol engine. It yields 191 kW/260 PS - the US version yields 244 hp - and 380 Nm torque, which is the same as Mazda’s high-performance MPS engine. The excellent performing engine was then matched with a six-speed manual transmission that is especially developed. With maximum speed limiter control and high-speed acceleration, the CX-7’s maximum speed tests were conducted along the expressways of Germany.
And because unique requirements for high speed stability are required by the European market, an extreme chassis testing was also conducted at Nürburgring’s “green hell” (the Nordschleife). To focus on overall body rigidity with reinforcements on different parts of the chassis was the first step. Then, the front cross members and the ones placed on the transmission tunnel were made thicker same as the front suspension towers.
Like any other driving experts, the feeling of being “in” to the road and the performance quality of the car are also the factors that European drivers consider. And the CX-7 assures those through its improved suspension. An example of this improvement is the enhanced layout and suspension settings on the pull bars that link the rear suspension to the body. This improvement assures an ideal give and take between agility and drive comfort. Furthermore, the tires, steering characteristics and ESP settings are all reinvented.
All these innovations plus the space and flexibility prepares the Mazda CX-7 to its flight to set a new standard in its segment in Europe. Every single characteristic of the Mazda CX-7 gives the European clients everything they could ever desire that would fit a multi activity lifestyle with high levels of driving pleasure.
