ZSHO ZG25 1.6Mpa Pneumatic Regulating Ball Valve Anti Static

A, pneumatic regulating ball valve features and USES

Pneumatic regulating ball valve is mainly used to cut or connect line in the medium, can also be used for flow regulation and control, compared with other types of valve, it has the following several advantages.

1, small fluid resistance, ball valve are all valve fluid resistance in the smallest one, even reducing ball valve, the fluid resistance is small.

2, thrust bearing, reduce the stem friction torque, and can make the valve stem long smooth and flexible operation.

3, seat sealing performance is good, use the seal ring made of elastic material, such as the structure is easy to seal, and valve ball valve sealing ability increases as the medium pressure increases.

4, the valve stem seal is reliable, due to the valve stem will only be used as turn 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 material has good self-lubrication, and sphere of friction loss is small, so the ball valve's service life is long.

6, the 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 can also be formed metal contact, to ensure that the valve stem seal.

7, anti-static function: set spring between ball, valve stem, valve body, the switching process can produce static export.

Second, pneumatic regulating ball valve actuators

Using new type GT series pneumatic actuators with double acting and single acting (spring reset), gear rack transmission, safe and reliable; Large diameter valve adopts series of AW pneumatic actuator fork type transmission, reasonable structure, large output torque, double-acting and single acting.

Double piston, gear type, the output torque, small volume.

2, selection of cylinder of aluminum alloy material, light weight, beautiful appearance.

3, can be installed in 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, at both ends of screw can make the standard product at 0 ° and 90 ° with a adjustable range of plus or minus 4 °. Ensure and synchronization accuracy of the valve.

The attachment option

According to different control and requirements can choose the following attachments:

Cut type attachment: single electronic control solenoid valve, double electric solenoid valves, limit switches back to the news.

DiaoJieXing accessories: electrical locator, pneumatic positioner, electrical converter.

Air handling accessories: air filtering pressure reducing valve, air source treatment sanlian pieces.

Operation manual: HVSD hand
