American standard cut-off Industrial Valves in the oil, gas, coal and ore, refining, processing and development of pipeline system; In the chemical products, medicine and food production species; Hydropower, thermal power and nuclear power production system; Cities and industrial drainage, heat supply, gas supply system. Six big advantage 1, manual handle part can be cast steel or stainless steel handle. Restricted the structure, the valve open and closed position limit setting, when the valve on the processing of key equipment use, can use the position of the lock switch is locked, to prevent the misuse of stopper. There are clearly marked and close the handle. 2, the stem is made of stainless steel ( 304. 321. 316. 316 l) Integral forging processing and modulation, through flat key spline or handle, multi-function, easy disassembling the deed tax connection HB220 ~ 250. The hardness of dry. Stem with blow-out proof design. 3, valve braided packing, flexible graphite seal or tetrafluoroethylene seals, the choice makes the Industrial Valves stem as part of the lubrication and reliable sealing. 4, according to the need, can be designed for ball valve and valve stem, valve stem and antistatic conductive spring structure, in order to avoid electrostatic ignition ignite flammable material, ensure the security of the system. 5, sealing form. According to the different situation can choose soft seal and hard seal, fire seat structure; 6 the following for floating ball form, DN200 for fixed ball form below. 6, the seat can be provided in the auxiliary seal structure, the installation of grease valve seat and valve stem, in an emergency, can temporarily seal, and according to the need to prevent a suitable place to be underground laying can be extended. Considerations for American standard cut-off valve can be according to your own channel position cut-through, three general formula and rectangular partition. After the two media for distribution, and changes in the media flow. Three-way ball valve installation and maintenance should be paid attention to the following: 1. Leaving the valve handle the location of the rotation. 2. Not be used for throttling. 3 and the transmission mechanism should be installed upright. American standard cut-off valve, American standard valve factory through rotary valve love to keep the valve open or occlusion. Ball Industrial Valves switch lightweight, small size, can make it big caliber, reliable sealing, simple in structure, easy to maintain, spherical and sealed in a closed state, often not easy to be in the field of various erosion has been widely used. American standard stainless steel globe valve is a relatively new type of valve type, it has a certain advantage of its unique structure, such as switch without friction, seal is easy to wear, small opening and closing torque. This reduces the actuator with the specifications. As more turn electric actuators can be regulated in the medium and carefully cut off.
The , essentially perfected by os gate valve, is one of the first home appliance to be widely distributed.
