pressure reducing valve is through flow control reduced the inlet pressure to a needed discharge pressure, and to rely on the energy of the medium itself, make the valve outlet pressure automatic remained stable. From fluid mechanics point of view, pressure reducing valve is a throttling element, local resistance to change that by changing the throttling area, change the kinetic energy of the flow velocity and fluid, different pressure loss, so as to achieve the goal of decompression. And then rely on the adjustment of the control and regulation system, make the valve after pressure fluctuations and spring force equilibrium, the Industrial Valves after pressure constant within a certain error range.

throttle valve is by changing the throttling section length or throttling to control the fluid and generate differential throttling effect. Normally, the appearance of throttle valve structure similar to stop valve, they're just the shape of the open-close part is different. Throttle Industrial Valves opening and closing of a streamlined, mostly cone through its change channel cross-sectional area and achieve the throttling refrigeration effect. Medium between the throttle valve disc and seat velocity is large, to these parts surface damage soon & ndash; The so-called cavitation phenomenon. In order to minimize the cavitation effect, disc cavitation resistant materials ( Alloy steel) And made from Angle of 140 top & deg; ~ 180度; Streamlined cone, which can make the disc can have larger opening height, usually under the small aperture throttling is not recommended. Throttle valve according to the passage ways can be divided into straight-through and Angle type two kinds; According to the shape of the open-close part points, have needle, ditch and window 3 kinds. The adjustable throttle valve and needle valve core is made of hard alloy products can be in accordance with the API6A standard design, has wear-resisting, scouring resistance performance. Sliding sleeve type throttle valve core structure of low noise balanced, open the light, the valve core is coated tungsten carbide, suitable for a flash, high pressure, high pressure and cavitation condition such as demanding situations, long service life, the flow control accuracy is greatly increased.
