According to reports, there was not much improvement in the granular potassium chloride market this week. Affected by the uncertainties of other fertilizer species and disputes between Uralkali Belaruskali, there has been no new progress in the procurement of potassium chloride in the market. At present, bulk grain potassium chloride is sold at a price of 320-322 euros, and buyers are expecting prices to be less than 300 euros. In the fourth quarter, the import price of potassium chloride is under discussion. In the third quarter, the price is 325-333 euros. Buyers will request a reduction on this basis.
Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.
People in developed nations use valves in their daily lives, including plumbing valves, such as taps for tap water, gas control valves on cookers, small valves fitted to washing machines and dishwashers, safety devices fitted to hot water systems, and poppet valves in car engines.
In nature there are valves, for example one-way valves in veins controlling the blood circulation, and heart valves controlling the flow of blood in the chambers of the heart and maintaining the correct pumping action.
Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or boilers.
More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
