Plastic Pressure Switch
Pressure switch is a simple pressure control device. When the measured pressure reaches the rated value, the pressure switch can give an alarm or control signal. At present, most of the existing pressure switches are made of metal materials. When the medium of gas or liquid circulating on the valve body is used, it will cause certain corrosion to the pressure switch itself; moreover, the ...

Why Sanitary Diaphragm Valves Are Ideal
The name diaphragm is derived from a flexible disc that comes into contact with a seat at the top of the valve to form a seal. Diaphragm valves are some of the most common valves on the market today. This valve is a flexible element that responds to the pressure transmitting force to open and close. This type of valve is in some way related to the pinch valves, but unlike pinch valves, the ...

Fully automatic prime/re-priming system handles air/liquid mixtures with ease
Cornell’s Redi-Prime® system addresses the fundamental requirement of customers to have pumps that are easy to operate, re-prime under lift condition, and eliminate carry-over issues of liquids when priming the pump. Repriming becomes important when entrainment (due to a snore condition) or vortexing occurs. The vacuum pump is always running, so when the liquid ...
