In the selection of logic valve, the system should be based on the required flow, greater than or equal to 200l / min when the use of two-way cartridge valve, less than 20l / min is the choice of threaded cartridge logic valve. Cartridge assembly cartridge with tail and without tail form, with the tail of the buffer and throttle and so on. There are a variety of valve core area ratio to choose from, the spring also has a variety of stiffness to choose from, in order to achieve a variety of opening pressure. Some domestic plug-in components in the spool and the valve sleeve with O-ring, which can ensure the seal, but the reaction speed. Damping holes in the control cover and the spool have a variety of diameters, large damping reaction hole reaction speed, but the impact of a large, small damping holes on the contrary. If the logic valve action will have an impact on the system's function, the choice of the diameter of the orifice should be particularly careful. There are many types of control covers and should be carefully selected according to the system. When designing the valve block, draw the positioning hole on the cover and designate the code of each port for assembly and maintenance. Should be based on the system flow and pressure and flow - pressure curve selection, too small will often result in system pressure loss is too large, the system fever, if the selection is too large, it will make the system huge, resulting in economic waste. There are two kinds of logic valve sealing material options, fluorine rubber seal suitable for phosphate media, nitrile rubber seal suitable for mineral oil media. Lined fluorine butterfly valve Due to its characteristics of high pressure and large flow rate, the logic valve is especially suitable for rapid hydraulic drive of the valve. It has mature logic valve products at home and abroad. Its application prospect in the rapid hydraulic drive of the valve is wide.

Tungsten carbide is a very hard and wear-resistant material, making it ideal for applications where high abrasion resistance is required. It is often mixed with other metals, such as nickel, cobalt, or chromium, to form a metal alloy powder. These metal alloys enhance the properties of the tungsten carbide and improve its compatibility with the base metal.
The tungsten carbide mix metal alloy powder is typically fed into the PTA welding torch, where it is melted and propelled onto the surface of the base metal using a high-energy plasma arc. The molten powder forms a hard, dense coating that bonds with the base metal, providing excellent wear resistance and protection.
The specific composition of the tungsten carbide mix metal alloy powder can vary depending on the application requirements. Different ratios of tungsten carbide and other metals can be used to achieve desired properties, such as hardness, toughness, and corrosion resistance.
Overall, tungsten carbide mix metal alloy powder is a versatile and effective material for PTA welding, offering superior wear resistance and protection for various industrial applications.
