ball valve

Characteristics of forged steel floating ball valve products

Using single bevel elastic sealing ring or V groove elastic sealing ring structure design, also can use plate spring metal valve seat structure of preloading.When medium pressure is too small, sealing ring and ball contact area is lesser, so have a bigger sealing pressure, ensure reliable sealing medium pressure, sealing ring and ball contact area increases, so the sealing ring can be larger medium thrust without damage.Because the seal materials such as ptfe ethylene has good self-lubrication, with the sphere of the friction loss is small, so the forging steel floating ball valve of long service life.According to the needs of users, can be designed to be applicable to the structure of the medium containing solid particles and slurry ring structure of high temperature resistance.

Forged steel floating ball valve installation instructions:
1, take off the protective cover on both sides of the flange end, under the conditions of valve fully open to wash clean.
2, before installation shall be in accordance with the provisions of signal (electric or pneumatic) on the test (to prevent due to transportation vibration impact performance), qualified rear can install (wiring according to the electric actuator wiring diagram).
3, preparation, and pipeline connection, you must wash and clean the pipe residual impurities (these substances may damage the seat and the ball).
4, during the installation, please don't use valve actuator part as a lifting of the lifting point, in order to avoid damage the actuator and accessories.
5, this kind of valve should be installed in horizontal or vertical direction.
6, installation of pipe with low or bear the phenomenon of external force, can use a pipe support or support to eliminate the deviation of pipelines.
7, and pipe connection, please use specified torque cross locking bolt flange connection.
