                  [valve features]
                  1, no maintenance, adjustment and lubrication, easy to install, low operating costs, long-term reliable operation. The surface is sprayed with plastic technology, and its luster is beautiful. It has been in the leading position in china. There will be no external leakage and so on. The valve body is welded so that the valve is light and easy to insulate. The adjusting mechanism is very simple. The operating handle can be disassembled and reversed.
                  2, because the seat is made of carbon fiber reinforced teflon seal ring and disc spring, so the change of the pressure and temperature adaptability, on the label will not produce any pressure and temperature range of sliding discharge.
                  3, the sphere of the processing process has advanced computer detector, tracking detection, so the ball machining accuracy.
                  4, because the material of the valve body is the same as the material of the pipeline, the stress is not uniform, and the pipeline can not be deformed because of the earthquake and the vehicle passing through the ground. The pipeline is resistant to aging.
                  5, integral type full welding, equal diameter and variable diameter passage, adopt fixed ball and floating ball, double piston effect sealing system, automatic Injection sealant type bearing.
                  6, in order to prevent static electricity, the valve stem and sphere as well as between the valve stem and the packing box are respectively equipped with the steel ball and the spring, can maintain the valve all parts and the valve body conduction, lets the electric current pass through the area, releases the static electricity. Not only to prevent fire, but also to prevent corrosion, temporary cutting, so as to timely maintenance.
                  7, stem anti stripping function is because the stem is affected by the pressure in the valve, the total produce from the force, so the stem is designed to prevent off structure.
                  8, Use a low friction thrust washer to push the pressure to the stem so that the stem acts only as a torque transmission.

                  [Adaptive condition]
                        The valve is an important executive mechanism of industrial automation control system, remote centralized control can meet the needs of computer program; now widely used in petroleum, chemical industry, gas equipment, nuclear power equipment, water treatment, air conditioning, iron and steel metallurgy, industrial furnace, tank equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, bio pharmaceutical, food machinery, textile, papermaking and other industries, the preferred product is construction of national defense construction, science and technology.
