First, Q41F stainless steel flange ball valve structure characteristics

1, the fluid resistance is small, the ball valve is the valve in all the fluid resistance of a minimum, even the reduced diameter ball valve, the fluid resistance is quite small. 
2, thrust bearing to reduce the stem friction torque, the stem can be long-term operation smooth and flexible.
 

Second, Q41F stainless steel flange ball valve use

Stainless steel flange ball valve for Class150 ~ Class1500, PN16 ~ PN100, JIS 10K ~ JIS 20K on a variety of pipelines, used to cut off or connect the pipe in the medium, use different materials, can be applied to water, Oil, nitric acid, acetic acid, oxidizing medium, urea and other media. This product can be widely used in papermaking, petrochemical, chemical, metallurgy, electricity, environmental protection, petroleum, light industry and other industrial automation systems.

 

Three, Q41F stainless steel flange ball valve structure characteristics

 1, the fluid resistance is small, the ball valve is the valve in all the fluid resistance of a minimum, even the reduced diameter ball valve, the fluid resistance is quite small. 
 2, thrust bearing to reduce the stem friction torque, the stem can be long-term operation smooth and flexible. 
 3, the valve seat sealing performance is good, the use of PTFE and other elastic materials made of seals, the structure is easy to seal, and the ball valve valve sealing capacity increases with the media pressure increases. 
 4, stem seal is reliable, because the stem is only imitation and movement without lifting movements, stem packing seal is not easy to damage, and the sealing capacity increases with the pressure of the medium increases. 
 5, due to PTFE and other materials with good self-lubricating, and the ball friction loss is small, so the long life of the ball valve. 
 6, the lower part of the stem and stem stem to prevent the stem stem spray, such as fire caused by stem seal damage, convex and the valve body can also form a metal contact to ensure that the stem seal. 
 7, anti-static function: in the sphere, stem, valve body set between the spring, the switch can produce static electricity derived.
 

Fourth, Q41F stainless steel ball valve actuator
With a new series of GT-type pneumatic actuators, 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, double acting and single acting. 
 
 1, gear-type double piston, the output torque, small size. 
 2, the choice of aluminum alloy cylinder material, light weight, beautiful appearance. 
 3, can be installed at the top, the bottom of the manual operating mechanism. 
 4, rack-type connection can adjust the opening angle, rated flow. 
 5, the actuator optional charge signal feedback and various accessories to achieve automatic operation. 
 6, IS05211 standard connection for the installation and replacement of the product provides a convenient. 
 7, both ends of the section of the screw can make the standard products in 0 ° and 90 ° ± 4 ° adjustable range. To ensure synchronization accuracy with the valve.

 

Fifth, Q41F stainless steel flange ball valve accessories options

 According to different control and requirements can choose the following accessories: 
 Cut off accessories: single solenoid valve, dual solenoid valve, limit switch switch. 
 Adjustable accessories: electrical positioner, pneumatic positioner, electrical converter. 
 Air handling accessories: air filter pressure relief valve, air handling triple pieces. 
 Manual mechanism: HVSD hand-held body.
