Stainless Steel Floating Ball Valve Soft Seated CF8M Manual Ball Valves FB 150LB

 

Description

Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves, but they lack their fine control in throttling applications.

Features
1. Switch Indication of Hand Operated Floating Ball Valve
As the moving parts of valve body, ball, stem and handle are an assembly unit. The head of valve stem is shaped a diploid, thus to easily distinguish whether valve is in the 'ON' position or 'OFF' position from handle position. When handle or stem diploid is in parallel with the pipe axis, valve is in 'ON' position; when handle
or stem diploid is vertical to the pipe axis, valve is in 'OFF position.
 
2. Valve Locking Device
To prevent mis-operation, the fully opened or closed position of valve can be locked up, especially when valves are mounted outdoors or when valves are not allowed to be opened or closed by technical process. To prevent misoperation by other persons, it seems very important to have valve position locked up. Thereby, lockhole locating tab is designed if requested by users to meet the technological requirements of users.
 
3. Anti-Blowout Structure of Valve Stem
When medium passes through the valve, the pressure in valve body may possibly push the stem out, or when the valve is in repair, if there is pressure in the middle cavity, the stem or medium seems to easily blow out upon disassembling the valve, which can cause injuries to person. To prevent these possibilities, a dummy club is placed at the lower part of the stem. In this way, even if there is fire, packing and thrust bearing are burnt or packing is damaged due to other causes, the pressure of medium in valve body will make the dummy club of valve stem in close contact with the upper seal face of valve body, thus to prevent medium leaking out from the damaged packing position.
 
4. Antistatic Device
When operating the valve, the friction between the ball and the nonmetal seat, like PTFE will produce electrostatic charge that can be accumulated on the ball. To prevent static spark, an antistatic device is placed on the valve to derive the electric charge accumulated on the ball from the static channel between the ball and the stem, or between the stem and valve body.
 
5. Fire Safe Structure
In case of fire, the nonmetal packing or seat (non-fireproof material) will be burnt, the considerable medium leakage may possibly cause fire spread. Here, the fire safe structure functions to prevent medium from mass leakage. As shown in the figure, once the seat is burnt, the ball will directly contact the metal face on valve body, thus to prevent medium leaking out from the burnt seat. The design of
fire protection and antistatic structure shall conform to the requirements of API607, JB/T6899 and the second part of BS6755.
 
6. Middle Flange Leak-tight Structure
The connection between valve body and the left body is sealed by gasket. To prevent seal leakage resulted from fire, high temperature or vibration etc., the valve body and the left body is designed metal-to-metal contacted, thus to form up a seal flange to ensure leak-tightness.
 
7. Self-Relieving Structure
In case of abnormal rise of pressure in the middle cavity of valve resulted from the medium left there suffered from changes of pipeline pressure or medium temperature, automatic pressure relief of valve seat can be effected under the pressure of the medium itself, thus to guarantee the safety of valve.
