Sanitary Valve :
A sanitary valve, as its name suggests, is a type of valve that meets the health standards (medical standards or food standards). The valve body must meet the health standards of stainless steel. All parts that contact with the medium are mirror polished. The degree of polishing and cleanliness must both meet the health standards of valve components. It's mainly used in sanitary areas of food processing, pharmaceutical factories and hospitals. It's also used in places with high requirements for health standards that tolerate no physical and chemical hazards.
There are requirements for the materials of valve body and sealing. The material used in most cases is stainless steel. The sealing surface of the valve seat must be non-toxic. For example, the material for hard sealing and soft sealing can be stainless steel and rubber, respectively.

The elevator wireless monitoring system simulates the wireless monitoring system and the digital monitoring system, respectively. Digital is divided into 5.8G wireless bridge and 2.4G wireless bridge. Because the wireless monitoring equipment is transmitted in a straight line, the conditions for realization are all visual and unobstructed. Therefore, the wireless bridge must be face-to-face, and the angle must be good. The installation position in the elevator is in the car section, the bottom and the top of the hoistway, and the bottom. If it is a car top mounted launcher, then the receiver must be installed opposite the top of the hoistway, ie top to top, bottom to bottom. 5.8G equipment installation can be top and bottom, more flexible. Because it is in a separate clean frequency band, the anti-interference ability is very strong. Below we illustrate the installation of analog wireless monitoring and 2.4 wireless bridges.
Both analog wireless monitoring and 2.4G wireless bridges are susceptible to interference. The top of the elevator car is generally equipped with motors, wires, and other devices that will interfere with these two wireless monitoring devices. The consequences of interference are likely to have an effect on the image effect and ripples and the like will occur. And when the elevator is running, the situation will be more serious. In many cases, customers will realize that there is a problem with the wireless monitoring device. It is actually a problem in the installation location. It is recommended that it be installed at the bottom of the car and at the bottom of the hoistway when installed so that interference can be effectively avoided.
Many customers did not pay attention to avoiding interference during the initial installation. As a result, they found that there was a problem with Leann’s equipment. Also pay attention to check the line, like many projects in the analog surveillance system are old project transformation, the original lines are relatively old. These are also prone to problems.
Don't worry when problems arise. Check them out one by one and always solve them. You can call Levin technicians. 
Wireless monitoring equipment is very simple and quick to install in elevators and does not require complicated engineering. However, because the elevator is a special place, there is a particular emphasis on the installation method.
