What is the main advantage of gray cast iron?The material offers great compressive strength similar to low-carbon / medium-carbon steel counterparts which tend to be less workable and more expensive.One unique advantage of gray cast iron is the enhanced damping property of the material. What is the difference between cast iron and grey cast iron?The […]

Pump CastingA pump is a mechanical device that moves fluids (liquids or gases, slurries.).  Pump casting is a process that pump parts are designed and cast by different metals or metal alloys.It can provide greater strength and corrosion resistance products and deals with liquid substances. What material is used for pump housing casting?Pump Casting parts, housing […]

What car parts are made of cast iron?Cast iron has good fluidity, high resistance to wear and deformation, making it the perfect material for many engineering projects.Automotive industry parts include cylinder heads, brake discs, crankshafts, and engine block. What automobile parts are made by casting?The major automobile components made using casting are pistons, engine blocks, valve covers, […]

What are the classification of pipe fittings?Pipe Fittings & Piping Systems ConnectionsThere are different kinds of pipe fittings used in piping systems.The main and most commonly sought are: elbows, tees, reducers, unions, couplings, crosses, caps, swage nipples, plugs, bushings, adapters, outlets, valves & flanges. What are the 4 types of pipe joints?Common types of pipe joints […]

What is the difference between iron casting and steel casting?The main difference between cast iron and carbon steel is the carbon content. Cast iron contains over 2% carbon, while steel contains less than 2% carbon. However, steel can also contain other elements like chromium. The addition of these elements results in steel of different qualities […]

The gate valve is one of the important pipe fittings in the pipeline for conveying fluid media,Is mainly used for cutting off the medium.It can only be fully opened, and cannot be used for flow adjustment.Its opening and closing part is a gate.The movement direction of the gate is perpendicular to the direction of the […]

Electric Non-rising Stem Soft Seal Gate Valve is composed of multi-turn electric actuator and flange gate valve, mainly used to open or cut off the medium in the pipeline, not suitable for adjusting the flow of medium, electric flange gate valve is suitable for pressure, temperature and caliber range is very large, especially suitable for medium and large […]

Casting production is a complex multi-process combined technological process, which includes the following main processes: 1) Production process preparation: Based on the part drawings to be produced, production batch and delivery time, formulate the production process plan and process documents, and draw the casting process diagram; 2) Production preparation, including the preparation of materials for […]

The control of valves can adopt various transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic-hydraulic, electro-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc. Under the influence of pressure, temperature or other forms of sensing signals, it can act as required, or simply open or close without relying on sensing signals. The valve […]

Cast iron parts are components obtained by melting metal into a liquid and pouring it into a mold, followed by cooling and treatment. Cast iron holds an important position in the foundry industry. The main types include: Gray cast iron parts: They have good fluidity and high compressive strength, and are widely used in engine […]

Cleaning and Finishing Once liberated from the mold through the artful process of shaking out, the iron casting process undergoes a thorough cleaning regimen. This isn’t a mere wipe-down; it’s a meticulous removal of any lingering vestiges of the mold material that clung to the surface during its formative phase. Following this, cast iron enters […]

Cleaning steps The components of the valve must undergo the following process treatment before assembly: 1. According to the processing requirements, some components need to be polished, and the surface must not have any processing burrs, etc. 2. All components undergo degreasing treatment. 3. After degreasing is completed, acid washing and passivation are carried out. […]

Connection method Flange connection This is the most commonly used connection form in valves. According to the shape of the mating surface, it can be further classified into the following types: 1. Smooth type: Used for valves with low pressure. It is relatively convenient to process. 2. Concave-convex type: It has a relatively high working […]

(2) Stop valves and throttle valves: Structural features of stop valves and throttle valves: It is mainly composed of the valve body, valve cover, valve stem, valve disc and handwheel, etc. Advantages and disadvantages of stop valves Advantages: Good sealing performance, with low friction on the sealing surface The phenomenon is not serious, maintenance is […]

(4) Ball Valve: 1.The structure of a ball valve: A ball valve is mainly composed of a valve body, a ball, a sealing ring, a valve stem and a driving device. 2. Features of ball valves: (1) Low flow resistance; (2) Simple structure and small volume; (3) Good sealing performance; (4) Easy to operate and […]

Electric Ball Valve Electric ball valves are used to control the cut-off of air flow and are generally not suitable for regulation. Therefore, their state should be fully open or fully closed. Ball valves are installed in the inlet and outlet stations, pigging device receiving and dispatching devices, and some bypass processes for crossing stations. […]

Check valve Check valves, also known as single-flow valves or one-way valves, belong to the category of non-return valve components. They are used to restrict the unidirectional flow of air and prevent backflow. There are two types: lift type and swing type. The check valves of our company are swing check valves. Its structural features […]
