Stainless steel ball valve is the market now has a lot of categories, with electric, pneumatic, and use, we here mainly introduce electric stainless steel ball, the ball is used to truncate or on line in the medium, can also be used to adjust and control of the fluid. Electric stainless steel ball valve compared with other types of valve, it has the following several advantages. 1, small fluid resistance, ball valve is the smallest of all valve fluid resistance in the class a, even reducing ball valve, the fluid resistance is small; 2, thrust bearings reduce stem friction torque, can make the valve stem long smooth and flexible operation;
3, seat sealing performance is good, use the sealing ring made of elastic material, such as teflon structure is easy to be sealed, and the ball valve seal ability increases as the medium pressure increases;
4, the valve stem seal is reliable, due to the valve stem will only be used as the rotation without lifting movement, the valve stem packing seal is not easy to damage, and sealing ability increases as the medium pressure increases;
5, such as ptfe material has good self-lubrication, with ball friction loss is small, so the ball valve's service life is long; 6, bottoms type valve stem and valve stem head convex order to prevent the valve stem, stem seal damage caused by such as fire, convex order between the body and also can form metal contact, to ensure that the stem seal;
7, anti-static function: in a sphere, the valve stem and valve body between spring, will be generated switching process of electrostatic export.
Electric stainless steel ball valve actuators using new series GT type pneumatic actuators, where net take phone have double-acting and single acting (spring reset), gear and rack driving, safe and reliable; Large diameter valve adopts series AW pneumatic actuator fork type transmission, reasonable structure, large output torque, a double-acting and single acting.
1, gear type double piston, output torque, small volume.
2, selection of cylinder aluminum alloy material, light weight, good appearance.
3, can be installed on the top and bottom manual operating mechanism.
4, the rack type connection adjustable opening Angle, rated flow.
5, actuators optional electric signal feedback instructions in order to realize automation and all kinds of accessories.
6, IS05211 standard connection provides convenience for the installation of the product replacement.
Section 7, both ends of the screw can make the standard product at 0 ° and 90 ° with a adjustable range of plus or minus 4 °. Ensure the synchronization precision with the valve. Electric stainless steel ball valve actuator attachment option
In accordance with the requirements of different control and can choose the following attachments:
Cut type accessories: single double electric control electric control solenoid valve, solenoid valve, limit switch back to the news.
External regulation accessories: electrical locator, pneumatic positioner, electrical converter.
Air handling accessories: air filtering pressure reducing valve, air source treatment sanlian pieces
