The commonly used materials for forged steel ball valves include carbon steel, alloy structural steel, martensitic stainless steel, and heat-resistant steel. Forged steel parts can use different annealing and normalizing methods to achieve different purposes based on the chemical composition of the steel.
The slag discharge gate valve is suitable for cutting off or connecting the medium in the pipeline of the slurry discharge system of thermal power plants and hydraulic engineering. The suitable medium is the ash water mixture, and the slag water ratio of the slag water mixture is ≥ 1:15. Slag discharge gate valve PZ41H PN10~PN63: manual, flange con1
The telescopic butterfly valve has the function of automatically compensating for the thermal expansion and contraction of pipelines for easy loading and unloading. It is the best device for regulating flow and breaking fluid on industrial pipelines such as petroleum, chemical, power, papermaking, water supply and drainage, and municipal constructi1
An electromagnetic valve is a fluid control element that is controlled by the moving piston of an electromagnetic coil to attract electromagnetic force. It is an actuator for automated equipment pipelines. Below are illustrated working principles of a direct piston type electromagnetic valve and a pilot piston type electromagnetic valve, with manua1
Electric flange ball valve has the same 90 degree lifting action, with a circular through-hole or channel passing through its axis. The ratio between the sphere and the channel should be such that when the sphere rotates 90 degrees, it should all appear spherical at the inlet and outlet, thereby cutting off the flow.
1、 Electric actuator details Electric actuators are used to control valves and other similar products that rotate from 0 ° to 270 °, such as butterfly valves, ball valves, dampers, plug valves, louver valves, etc. They can be widely used in various industries such as petroleum, chemical, water treatment, shipbuilding, papermaking, power plants, hea1
QJ41M high-temperature ball valve/QJ641M pneumatic high-temperature ball valve/QJ941M electric high-temperature ball valve is a ball valve that uses a new sealing material as the valve seat and is sealed with similar products such as polytetrafluoroethylene. Its service life has been increased by 3-5 times. High temperature ball valves have advanta1
The PZ273H electro-hydraulic knife type gate valve controls the opening and closing of the valve through the reciprocating push position of the electro-hydraulic linkage device. If equipped with sensors or digital display devices, it can be centrally or programmatically controlled in remote and high-altitude hazardous areas. It is widely used in in1
