Product description
Plastic globe valve is a widely used valve. The reason why it is so popular is that the friction between the sealing surfaces during the opening and closing process is small, it is relatively durable, has a small opening height, is easy to manufacture, and is convenient to maintain. The closing principle of low pressure and high pressure plastic globe valve is to rely on the pressure of the valve stem to make the sealing surface of the valve clack closely fit the sealing surface of the valve seat to prevent the medium from flowing. The plastic globe valve only allows the medium to flow in one direction, and it is directional when installed. The structural length of the plastic globe valve is longer than that of the gate valve. At the same time, the fluid resistance is large, and the sealing reliability is not strong during long-term operation.
lastic globe valve has the following advantages:
1. Simple structure, convenient manufacturing and maintenance;
2, the working stroke is small, and the opening and closing time is short;
3. Good sealing, small friction between the sealing surfaces, and long life.
The plastic globe valve body is light in weight, strong in corrosion resistance, compact and beautiful in appearance, light in weight, easy to install, strong in corrosion resistance, wide range of applications, materials are hygienic and non-toxic, wear-resistant, easy to disassemble, easy to maintain, and applicable Fluid: water, air, oil, corrosive chemical liquid.
