Low-pressure steam pipelines are usually used in equipment or processes that require low-temperature and low-pressure steam, such as building heating and ventilation, sanitary hot water, food processing, etc. This kind of pipeline system is relatively simple, usually using materials such as ordinary carbon steel or stainless steel, and equipped with corresponding control valves and monitoring equipment.

Why Do Steam Pipelines Need Valves?

For automation systems, steam pipelines can also be integrated with automatic control equipment and sensors to achieve automatic control and monitoring.
Use electric actuators or pneumatic actuators to control valves to adjust the flow and temperature of steam, and use temperature sensors and pressure sensors to monitor the temperature and pressure in steam pipelines, etc.

5 Types Of Valves That Can Be Used In Steam Pipelines

Steam pipelines usually need to be equipped with various types of valves to control the flow, pressure and direction of steam. Here are some commonly used valve types:

Globe Valves

Globe valves are one of the most common types of valves that can be used to control the flow and pressure of steam. When the valve is closed, it shuts off the flow of steam completely.

Control Valves

Regulating valves can be used to control the flow and pressure of steam and maintain a constant flow or pressure. It is typically used in applications that require continuous adjustment of steam flow.

Safety Valves

A safety valve is a special valve that opens automatically when the pressure in a pipeline exceeds a safe limit to prevent pipeline rupture or other dangerous events from occurring.

Check Valves

A check valve prevents the steam from flowing backwards in the pipe and maintains one-way flow. This is very important for applications that need to prevent backflow.

Shut-Off Valves

Like ball valve and butterfly valve for controlling the shut-off performance. Helping to transport or cut-off the flow rate.

The above are some commonly used valve types, and the appropriate valve can be selected according to the actual application needs.

How To Choose The Right Actuator?

High Temperature Resistance

Since the temperature in the steam transmission pipeline is usually high, the electric actuator or pneumatic actuator should be able to withstand the high temperature environment to avoid damage or burnout of the actuator due to high temperature.

Preservative

The steam in the steam delivery pipeline often contains moisture and other corrosive substances, which may corrode the actuator parts, resulting in actuator damage or performance degradation. Therefore, the actuator material should have strong corrosion resistance.

Dustproof And Waterproof

Since steam pipelines are usually in an industrial production environment, electric or pneumatic actuators should be dustproof and waterproof to ensure long-term reliable operation.

Quick Response

Steam delivery pipelines usually require frequent adjustments, so the actuator should have fast response capabilities so that it can respond to control signals quickly and accurately.

Low Maintenance Cost

Since the steam transmission pipeline is usually a long-distance, large-scale pipeline system, the maintenance cost of the actuator should be as low as possible to avoid the problem of high pipeline maintenance and management costs.

Therefore, for the selection of actuators in steam pipelines, the above requirements need to be considered, and comprehensive evaluation and selection should be carried out according to actual application conditions.

Tips For Selecting The Valve For Alkali Recovery Treatment

Alkali recovery treatment is a subdivision field in wastewater treatment, and it is also a technology that has received the most attention at present. The paper industry, textile industry, electronic production industry, and chemical industry will produce wastewater containing alkaline substances due to the characteristics of their processing processes. If this type of wastewater is discharged directly without treatment, it will pollute the soil and water, and affect the human living environment and the balance of the ecosystem.

What is alkali recovery treatment?

Alkali recovery treatment refers to the recovery and reuse of chemical substances in wastewater containing alkaline chemical substances, through liquid-solid separation, recovery of chemical substances, acid neutralization, precipitation and other steps to separate chemical substances, alkaline substances and water. The purpose of the technology is to recover and reuse chemicals, as well as improve the recycling rate of water resources.

Benefits of Alkali Recovery Treatment

Through alkali recovery treatment, the discharge of waste water can be effectively reduced, the utilization rate of chemical substances can be improved, energy consumption can be reduced, and raw materials can be saved. Therefore, alkali recovery treatment is an environmentally friendly and sustainable technology.

During the alkali recovery process, the liquid needs to be transported to different processing equipment and storage tanks through pipelines, so it is necessary to use valves to adjust the flow, adjust the pressure or change the flow direction of the liquid, so that the liquid can be transported smoothly and the entire process can be effectively controlled.

5 Types of Valves Common Used In Alkali recovery treatment

Every kind of wastewater treatment will have more than 2 processing processes, and the same is true for alkali recovery treatment. Depending on the process, different types of valves may be required.

In the liquid-solid separation stage, knife gate valves, diaphragm valves or butterfly valves are required to control the flow of inlet and outlet. Since the liquid at this stage contains impurities, it is easy to block the valve, so we need to use a knife gate valve to avoid system shutdown caused by blockage. After the crystals in the medium are separated, flow control can be performed using a diaphragm valve or a butterfly valve.

In the alkali recovery stage, we need to use regulating valves to control parameters such as the heating temperature and pressure of the evaporator to ensure the smooth and safe operation of this stage.

Acid neutralization is a process of raising the pH value of wastewater to neutral or alkaline, so as to meet the water quality requirements of discharge standards. In this process, control valves such as ball valves or globe valves will be used to control liquid delivery and emission.

All of the above valves can be equipped with electric actuators or pneumatic actuators, so as to achieve the purpose of fluid automation and improve project processing efficiency.

In summary, alkali recycling is an environmentally friendly technology that can help maintain the overall ecological balance. Unused processes will have different requirements on the valves, so we must choose carefully. Anything we could help, feel free to consult us at sales@covnaactuator.com
