Two-Piece Ball valve

Product details: 
Two-Piece Ball valve Ball valve only need to rotate 90 degrees of operation and a small torque can be closed tightly. Full equality body cavity for the media to provide a little resistance, through the flow channel. Ball valve is generally considered the most suitable for opening and closing done directly used, but recent development has been designed to make it a Ball valve and control the flow of the throttle. 
Nominal pressure: 1.6-6.4MPA 
Applicable medium: water, oil, gas and some corrosive liquids. 
Drive way: manual, pneumatic, electric, hydraulic, and other major performance characteristics: variation in temperature difference; Atmospheric pressure 1.6MPA, 2.5MPA, 4.0MPA, 6.4MPA; corrosion using Cast steel, carbon steel, Stainless steel 301, 304, 316Materials made connection: quick, thread, welding. 
Commonly used in the food, pharmaceutical, oil, electricity, dairy products, beverages, chemicals and various fluids Equipment in. 

main feature: 
Its own compact, easy operation and maintenance for water, solvents, acids and gas work in general media, but also applies to the poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be overall, it can be combined, such as one-piece Ball valve, two-piece Ball valve, role: 
Mainly used for switch, cut off or connected line of medium, can be used for fluid regulation and control of. 
Ball valve Applications: chemical, petrochemical, oil, paper, mining, electricity, gas, food, pharmaceutical, water supply and drainage, municipal, mechanical Equipment Supporting, electronics industry, urban construction and other fields. 
Installation Notes: 
(1) Remove Flange end of both sides of the cover, under the valve is fully open state to wash clean. 
(2) should be required prior to the installation of a signal (electric or pneumatic) performed the test machine (to prevent vibration from transport performance), after passing the line installation (wiring by electric actuator wiring diagram). 
(3) Preparation and front pipe connections, to be washed and cleaned of impurities remaining in the pipeline (of these substances may damage the valve seat and ball). 
(4) During the installation, please do not use the actuator as the lifting portion of the valve lifting points to avoid damage to the actuator and accessories. 
(5) The class valve should be installed in horizontal or vertical pipe. 
(6) installed near the pipeline should not have to bear falls or external phenomena, you can use pipe support or supports to eliminate the deviation from the line. 
(7) connected to the pipeline, with a specified torque cross locking Flange connection bolt.
