Stainless steel ball valve now the market is there are many categories, electric, pneumatic and use dynamic, we here basically introduces electric stainless steel ball ball, used to cut off or on line of medium, can be used for the fluid regulation and control. Electric stainless steel ball valve and other valve than class, has the following some advantages.
1, fluid resistance is small, ball valve is all valve class fluid resistance minimum one kind, even reducing ball valve, the fluid resistance is small;
2, thrust bearing reduce stem friction moment, can make the valve rod long-term operation smooth agile;
3, seat sealing performance is good, the teflon and elastic material made of seal ring, the structure is easy to seal, and ball valve valve sealing ability with medium pressure increases with the increased;
4, stem seal reliable, because stem will only be shipped as rotation without lifting movement, stem packing is not easy to damage, and sealing ability with medium pressure and increase,
5, because ptfe etc material has good self lubrication and friction losses small ball, the ball valve life long;
6, remove theatrical makeup and costume type of valve stem and valve stem head convex order to prevent the valve rod extrusion, such as fire cause stem seal failure, convex order and valve body, still can form between metal contact, to ensure that the valve stem seal;
7, anti-static function: in the sphere, the valve stem, the body can be set up between spring switch process is to produce static derived.
Electric stainless steel ball valve actuator using new series GT type pneumatic actuators, double acting and single acting (spring reset), rack and pinion, safe and reliable; The large diameter valve series AW type pneumatic actuator fork transmission, reasonable structure, large output torque, double acting and single acting.
1, gear type double piston, the output torque, small volume.
2, cylinder choose aluminum alloy material, light weight, beautiful appearance.
3, can be in the top, bottom, installation manual operating mechanism.
4, rack connection can adjust the opening Angle, the rated flow.
5, actuator optional charged signal feedback directives and all kinds of accessories to realize automation.
6, IS05211 standard connection for the installation of the product change provides convenient.
7, both ends adjustable pitch screw can make the standard product at 0 ° and 90 ° ± 4 ° have adjustable range. To ensure that the valve and the precision of the synchronization.
Electric stainless steel ball valve actuator accessory options
According to the different control and requirements can choose the following attachments:
Cut type accessories: single electric solenoid valve, double electric solenoid valve, limit switch back - device.
DiaoJieXing accessories: electrical locator, pneumatic positioner, electrical converter.
Air processing accessories: air filtration pressure reducing valve, air handling triple a.
Manual mechanism: HVSD hand operating mechanism
