The application of stainless steel valves in the industry

Stainless steel valves refer to valves with stainless steel as the valve body material. Due to their excellent rust resistance and corrosion resistance, they are widely used in multiple industries, as follows: I. Food Industry Stainless steel valves are widely used in the production lines of the food industry, such as those for biscuits, instant noodles and rice noodles, as well as in the dehydration production line equipment for frozen foods. These valves can ensure hygiene and safety during the food production process, while meeting the control requirements for fluid flow and pressure. Ii. Petroleum and chemical Industry In the petroleum and chemical industries, stainless steel valves are widely used due to their excellent corrosion resistance. They can resist the erosion of various corrosive media, ensuring the stability and safety of the production process. In addition, stainless steel valves can precisely control fluid flow, meeting various demands in the production process.

What are the simple reasons for the heating of valve electric actuators? How to solve it?

Overheating of valve electric actuators is a common fault phenomenon, which may affect equipment performance, shorten service life and even cause safety accidents. The following are the simple causes of fever and the corresponding solutions I. Common Causes of Fever 1. Motor overload • Causes: Valve jamming, excessive load (such as valve torque exceeding actuator rated value), transmission component jamming (such as lack of oil in the gearbox). • Phenomenon: The motor temperature rises sharply, accompanied by an abnormal increase in current. 2. Power supply issue • Causes: Excessively high or low voltage (deviating from the rated value by more than ±10%), three-phase imbalance (phase-to-phase voltage difference > 5%). • Phenomenon: The motor operates unstably and the heating is uneven. 3. Poor heat dissipation • Reasons: Poor ventilation at the actuator installation location (such as in a closed cabinet), dust accumulation on the heat sink

Design and structural characteristics of forged steel gate valve

The design and structural characteristics of forged steel gate valves are mainly reflected in the following aspects: Design Features 1. Application and medium adaptability: Forged steel gate valves are mainly used to cut off or connect media in pipelines, suitable for the working pressure range of Class 150~2500, as well as the working temperature range of -29~425 ℃ (carbon steel) or -29~500 ℃ (stainless steel). Different materials can be selected to adapt to various media such as water, steam, oil, acetic acid, oxidizing media, urea, etc. 2. Sealing performance: The sealing surface of forged steel gate valves is less susceptible to erosion and erosion by the medium, with good sealing performance and long service life. When fully opened, the sealing surface is less eroded, ensuring good sealing effect. 3. Fluid resistance: The internal medium channel of the forged steel gate valve body is straight through, and the flow direction of the medium through the gate valve does not change, so the fluid resistance is small.
