1. Independent upper valve cover ensures that the packing will not be worn by particles in the medium, thus damaging the valve stem;The sleeve with self-cleaning effect, on the one hand to ensure the stability of the spool, on the other hand, the spool has a self-cleaning effect.
2.Smooth flow channel, the flow channel on the fluid interference is small.The special material of the spool and the base adopts the nested technology and positioning technology owned by Fisher, which ensures that the spool will not loosen or even fall off during the intense scouring and vibration.
3. The specially designed venturi outlet of Fisher 461 Sweep-Flo Angle Valve – Fisher ensures that a large amount of gas resolved can be discharged from the valve chamber quickly, so as to ensure that the liquid level of the cooling chamber and washing tower will not be abnormal due to pressure after the valve, without affecting the whole process, but also reduces the damage of flash and rinse.
4.The valve cavity space, coupled with a solid upper and lining guide, so that the valve action is more stable.The valve body with a flushing port, through the field external liquid or gas flushing, clean the entire valve internals and valve chamber, thus improving the control performance of the valve and extend the service life.
