Q41F Flanged cast steel ball valve, flanged ball valve, cast steel ball valve

Q41F Flanged cast steel ball valve structure features:

1, the fluid resistance is small, ball valve is one of the small fluid resistance of all valves, even the reduced diameter ball valve, its fluid resistance is quite small.

2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.

3, the sealing performance of the seat is good, the sealing ring made of polytetrafluoroethylene and other elastic materials, the structure is easy to seal, and the sealing capacity of the ball valve increases with the increase of the medium pressure.

4, the valve stem seal is reliable, because the valve stem is only as if rotating without lifting movement, the packing seal of the valve stem is not easy to destroy, and the sealing capacity increases with the pressure of the medium.

5, because polytetrafluoroethylene and other materials have good self-lubrication, and the friction loss of the ball valve is small, so the service life of the ball valve is long.

6, the lower mounted valve stem and valve stem head convex step to prevent the valve stem ejecta, such as fire caused by the valve stem seal damage, the convex step and the valve body can also form metal contact to ensure the valve stem seal.

7, anti-static function: set the spring between the ball, valve stem and valve body, which can export the static electricity generated by the switching process.

This product can be widely used in papermaking, petrochemical, chemical, metallurgy, electric power, environmental protection, petroleum, light industry and other industrial automation control system. The floating ball valve has two structural forms of full diameter and reduced diameter. Ball valves used for conveying viscous, slagging medium pipelines should be used in full diameter to facilitate the passage of regular wax scrapers and purifiers. For conveying gas or medium with physical properties similar to water, it is appropriate to use a reduced diameter ball valve on the pipeline, because its weight is about 30% lighter than a full-diameter ball valve, which is conducive to reducing pipeline load and reducing costs. The driving mode of floating ball valve is manual, worm gear transmission, pneumatic, electric or hydraulic

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.

Q41F Flange cast steel ball valve actuator:

Ball valve using a new series of GT type pneumatic actuators, double acting and single acting (spring return), rack and pinion drive, safe and reliable; Large diameter valve adopts series AW type pneumatic actuator fork drive, reasonable structure, large output torque, double acting and single acting.

1, gear type double piston, output torque is large, small volume.

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

3. Manual operation mechanism can be installed at the top and bottom.

4, rack type connection can adjust the opening Angle, rated flow.

5, the actuator can choose live signal feedback indication and various accessories to achieve automatic operation.

6. IS05211 standard connection provides convenience for the installation and replacement of the product.

7, both ends of the adjustable screw can make the standard product in 0° and 90° have a ±4° adjustable range. Ensure accurate synchronization with the valve.
