The intelligent trend of valve industry is obvious
In addition to being used in the above environment, knife gate valve can also be used in fluids with solid particles, such as common wastewater or sludge cleaning systems. Generally, in order to meet the actual application requirements, the knife gate valve is usually designed to be sealed on the upstream side of the circuit (i.e. the fluid inlet side), but some valves go the opposite way and are sealed on both sides. Therefore, the knife gate valve can be used to achieve the purpose of flow control under any working condition and environment and fluid flow direction. In the open position, the head loss of the valve is very low because the valve will not cause a change in fluid direction. However, the closing and opening time may be very long, so the valve needs regular maintenance to correct the wear between the valve and the seal, which can also prolong the service life of the valve.
The Altitude Valve controls the high water level in reservoirs.
The Suzhou Walter Flow Control Equipment Co.,Ltd. Model A010 Altitude Valvecontrols the high water level in reservoirswithout the need for floats or otherdevices. It remains fully open until the shut-off level is reached. This valve is designed for one-way flow only.
This valve is hydraulically operated and pilot controlled. The pilot control operates on the differential in forces between a spring load and the water level in the reservoir. The desired high water level is set by adjusting the spring force.
The pilot control measures the reservoir head through a customer supplied sensing line connected directly to the reservoir.
The spring of pilot is according to the height of shut-off level.
