                  [Valve features]

                         Pneumatic fixed ball valve, ball valve is two-way valve, unrestricted flow. The middle flange is stud connected, and the upper and lower valve stems are provided with sliding bearings to reduce friction, and the operation is labor-saving and smooth. Under normal circumstances: low pressure when the valve seat sealing by spring preload to the seat close to the ball to seal, pressure is high, the formation of the piston effect on the seat, in the role of the upstream medium under pressure, the valve seat is pressed ball to seal, the products are widely used in open or closed system implementation process control system.


                  [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.
