American TYLER TYLER imports pneumatic globe valves
Product description -
The American Taylor pneumatic globe valve adopts double acting cylinder, which USES compressed air to air inlet or lower chamber to control the valve at long distance, which is convenient and flexible. Simple structure, convenient manufacturing and maintenance; Small working schedule and short opening time; The closed body (disc) and seat sealing face are conical sealing, small closing force, erosion resistance and reliable sealing.
Application scope -
Electric valve is a pipeline fluid control general equipment used in petroleum, chemical, water, oil, gas, heat conduction oil, natural gas, steam, hot water, corrosion and non corrosive medium, such as nitric acid, acetic acid,
Product features -
The selection of materials, meeting relevant standards, reasonable structure, beautiful shape;
The valve disc, seat is made of iron base alloy surfacing or the stacking of the cobalt base hard alloy, wear resistance, high temperature resistance, corrosion resistance and good abrasion resistance.
The valve stem has good corrosion resistance and abrasion resistance.
The inverted seal adopts the threaded joint sealing seat or the body to weld austenitic stainless steel and the sealing is reliable.
Relatively short opening or closing;
