A small share of sanitary tank bottom valve

What is the sanitary tank bottom water valve?

A sanitary tank bottom valve is a valve installed at the bottom of a tank to empty the tank, fill the tank or drain the water when needed. The process occurs with minimal dead space. Sanitary tank bottom valves have a conical shape that drains the tank while preventing the occurrence of dead spots and areas that trap dirt in the tank. They are widely used in the dairy, beverage, food processing, chemical and pharmaceutical industries.

About the type of sanitary tank bottom valve

1.Sanitary box bottom ball valve

The sanitary tank bottom ball valve is available in different sizes and materials. It can withstand a temperature range of -30 to 130 degrees Celsius. It withstands a maximum pressure of 10 bar, making it one of the best valves for storage tanks. The valve operates with minimal torque, making it easy to use and economical in terms of power usage. The valve handle can be mounted on the tank wall despite the flowing ions. It can also be easily replaced despite this connection in the tank.

2.Sanitary box bottom diaphragm valve

The principle of operation of the diaphragm valve at the bottom of the tank is simple. In its usual state, the diaphragm is closed, at which point it fits snugly into a cavity in the valve body. It shuts off the flow of water through the piping when it is necessary to clean or discharge the water in the tank. For the valve connection, it can be optionally clamped or welded into the tank.

3.Anti-mixing sanitary tank bottom valve

The anti-mixing sanitary tank bottom valve is operated automatically by one or two working pneumatic actuation systems. When compressed air is supplied to the valve, the valve spindle moves to open the valve in the closed position. Afterwards, the valve seat opens in the tank. Thus, it prevents accidental opening of the tank when excessive pressure is applied to the pipeline. In addition to those highlighted above, there are many other types of sanitary tank bottom valves.

The method of fixing the bottom valve of water tank

There are two methods of securing sanitary tank bottom valves. These methods include.

1. Bolting

Bolting involves the use of a number of nuts to secure the sanitary tank bottom valve. Metal bolts securely hold the valve in place for its purpose.

2. Welding

Welding involves the use of some high temperature electrical heat to hold the valve in place. The valve is welded to the bottom, usually where it is emptied and drained.

Areas of use

The sanitary tank bottom valve has a wide range of applications. It is mainly used in the beverage industry, chemical, pharmaceutical and food processing industries. These are the places where evacuation and discharge is mainly done in the manufacturing process. The valve simplifies the activities and thus minimizes the time required for the process of manufacturing beverages and chemicals.

Design features of sanitary tank bottom valves

1.3A compliant design

Sanitary valves are designed to follow the highest standards of hygiene and sanitation. This is to ensure that the fluid inside the tank is not contaminated. Keep in mind that these tubes are used in beverage manufacturing as well as pharmaceuticals. Of course, humans ingest beverages, so sanitation is sought in valve manufacturing as well. 3A standards were developed in the 1920s for milk piping fittings. Since that time, it remains the set of standards for all piping that carries fluids for human consumption.

2.Complete discharge system to avoid stagnation

Sanitary valves should be manufactured so that they do not retain any fluid in the system. They will perform an absolute drain, thus keeping both the piping and the tank clean. This is one of the measures taken by valve manufacturers because retained fluids can contaminate fresh fluids. When valve systems are used in the beverage industry, the risk to human health is even greater.

3.Normally closed (NC) by default, the NC and NO functions can be interchanged by rotating the cylinder 180°

The sanitary tank bottom valve has a normally closed and normally open function. The two can be interchanged by simply rotating the cylinder within an angle of 180 degrees. This makes opening and closing the valve a very easy process.

4.360° adjustable valve body, even after welding to the tank

After the sanitary valve is connected to the tank by welding, it is still possible to rotate the valve for 360° adjustment. The possibility of change increases the flexibility of how the sanitary valve works.

5.Open carry light for visual inspection of shaft seals

To observe the operation of the sanitary valve, an open tilting lamp can be used. Thus, the shaft seal and its operation can be checked. This means that all necessary corrections and adjustments can be made to the valve to enhance its working capacity.

6.Easy assembly/disassembly by loosening the clamp at the center of the valve body

Assembly and disassembly of the sanitary valve can be easily performed by loosening the clamp at the center of the valve body. This makes it easy to make all necessary adjustments to the valve.

How to choose a high quality sanitary tank bottom valve

With the wide variety of valves available in today’s market, choosing the best valve becomes a battle of evaluation. Some of the things to consider when purchasing a sanitary valve include material, desired size, purpose and method of connection. Other considerations include the resistance of the valve, the internal surface of the valve and the actuation of the valve.
