Stainless steel flange ball valve

Stainless steel ball valve flange for Class150 ~ Class1500, PN16 ~ PN100, JIS 10K ~ JIS 20K of the various pipelines, used to cut off or connect the media in the pipeline, choose different materials, respectively, for water, steam, Oil, nitric acid, acetic acid, oxidizing media, urea and other media. This product can be widely used in papermaking, petrochemical, chemical, metallurgy, electric power, environmental protection, petroleum, light industry and other industrial automation control system.

Second, Q41F stainless steel flange valve structure characteristics

 1, the fluid resistance is small, the ball valve is the smallest of all valves fluid resistance, even a reduced diameter ball valve, the fluid resistance is quite small. 
 2, thrust bearing to reduce stem friction torque, valve stem long-term operation can be smooth and flexible. 
 3, the valve seat sealing performance is good, the seal ring made of elastic material such as PTFE, the structure is easy to seal, and the ball valve sealing ability increases with the increase of medium pressure. 
 4, the stem seal is reliable, because the stem only fake rotary motion without lifting movements, stem packing seal is not easy to damage, and the sealing capacity increases with the media pressure increases. 
 5, due to PTFE and other materials with good self-lubricating, and friction loss of the ball is small, so the long service life of the ball valve. 
 6, Bottom stem and valve stem convex steps to prevent the valve stem ejected, such as a fire caused by the stem seal damage, convex step and the body can also form a metal contact between the stem to ensure that the seal. 
 7, anti-static function: set the spring between the ball, stem, valve body, the static electricity generated by the switching process can be exported.
 

Third, the Q41F stainless steel ball valve actuator
 using a new series of GT-type pneumatic actuators, a double-acting and single-acting (spring reset), rack and pinion drive, safe and reliable; large-diameter valve with a series of AW-type pneumatic actuator fork Transmission, reasonable structure, large output torque, a double-acting and single-acting. 
 
 1, gear double piston, output torque, small size. 
 2, aluminum cylinder material selection, light weight, beautiful appearance. 
 3, can be installed in the top, bottom manual operating mechanism. 
 4, rack-type connection can be adjusted open angle, rated flow. 
 5, the actuator optional electrical signal feedback instructions and various attachments in order to achieve automation. 
 6, IS05211 standard connection for the installation of the product provides a convenient replacement. 
 7, both ends of the pitch adjustment screw can make the standard product in 0 ° and 90 ° ± 4 ° adjustable range. To ensure synchronization with the valve accuracy.

Fourth, Q41F stainless steel flange ball valve attachment options

According to different controls and requirements can choose the following accessories: 
 Cut-off type Accessories: Single solenoid valve, dual solenoid valve, limit switch back to the device. 
 Adjustable accessories: electrical locator, pneumatic positioner, electrical converter. 
 Air treatment accessories: air filter valve, air handling triplet. 
 Manual mechanism: HVSD hand-operated mechanism.
