Tips For Selecting The Valve For Ammonia Service

Ammonia is an important chemical raw material, widely used in chemical fertilizers, medicine, plastics, synthetic fibers, coatings, dyes and other industries. At the same time, ammonia is also used in refrigeration, freezing and air conditioning and other fields.

● In the chemical industry, ammonia is an important raw material for the preparation of urea, nitric acid, sulfuric acid, carbamic acid and other chemical products.

● In the agricultural industry, ammonia can be used to prepare agricultural products such as pesticides and fertilizers, and can also be used as an animal feed additive.

● In the food industry, ammonia can be used to prepare flour, bread, biscuits and other foods, as well as protein foods.

● In different industries, ammonia can be used to produce different finished products, which is a necessity for human development and life.

However, it should be noted that ammonia is toxic and irritating and has certain hazards to the human body and the environment. Safety measures must be taken during use and storage. Therefore, during the transportation of ammonia, we need to choose high-quality pipes, valves and other accessories to ensure the normal transportation of ammonia without leakage.

Types Of Valve For Ammonia Service

● Ball Valve

The advantages of the ball valve are simple structure, flexible switching, and good sealing, which is very suitable for the cut-off of ammonia flow control. Ball valves can be divided into threaded ball valves, flanged ball valves, etc. according to design standards. According to the application scenario, the ball valve can be customized into high temperature style, high pressure style, etc. to meet different application conditions.

● Gate Valve

The gate valve has good sealing performance, simple structure and corrosion resistance. Since the gate valve can only be fully opened or fully closed, the gate valve is very suitable for the cut-off and flow control of ammonia gas.

Gate valve and ball valve both could equip with electric actuator or pneumatic actuator to help to control the valve automatically and remotely.

● Safety Valve

The safety valve is a valve used to protect the safety of the system. It is suitable for safety protection in the transportation of ammonia to ensure the normal operation of pipelines and systems.

Tips For Selecting The Valve For Ammonia Service

When selecting a valve for ammonia service, it is necessary to select a suitable valve based on the characteristics and transportation conditions of the ammonia gas.

● Valve Material

Ammonia gas is corrosive and has high requirements for valve materials. It is necessary to choose corrosion-resistant materials, such as stainless steel, PVDF and other anti-corrosion materials, to ensure pipeline safety.

● Valve Type

It is necessary to select the appropriate valve type, such as ball valve, butterfly valve or gate valve, according to the flow and direction of ammonia gas, as well as the production process.

● Valve Size

It is necessary to select the appropriate valve size according to the size of the ammonia transportation pipeline to ensure that the connection between the valve and the pipeline is tight and no leakage occurs.

● Sealing Performance

Ammonia is a volatile gas, and it is necessary to choose a valve with good sealing to ensure that the ammonia will not leak.

● Valve Safety

When choosing a valve, it is necessary to consider the safety of the valve, such as whether it has functions such as overpressure protection and overtemperature protection, so as to ensure the safety of the ammonia transportation process.
