Product Description

Floating Ball Valve

Structure and Working principle

(1) Indication of valve’s open and close position

Ball, stem and handle are one assembly unit. The stem head is a flat-square structure and the valve is easy to be seen either in the open or close position from the handle is in. When the handle or the flat-square of the stem head is parallel with the pipeline , the valve is in the fully open position ; while in the fully close one when vertical to the pipeline.

(2) Locker

To prevent mal-operation of the valve, a hanging lock can be used to lock it when in the fully open or close position, which is very important especially for the valve mounted outside or not allowed to be opened or closed by the technological flow.

(3) Stem fly-proof structure

The stem may be pushed out by the pressure in the middle cavity of the body when the medium goes through the valve. To prevent this, a fly-proof structure is made on the lower part of the stem (Fig.1). In this way, even if the packing and/or thrust bearing are burnt out in a fire or damaged by other cause, the medium’s pressure inside of the body will have both stem flange and upper sealing face of body tightly contacted so as to prevent a lot of medium from leaking from the damaged packing place.

(4) Electrostatic-proof device and fire-fighting structure

Both electrostatic-proof device (Fig.2) and fire-fighting structure (Fig.3) are designed. Once the seat ring is burnt out in case of a fire, the ball would be directly contacted with the metal face of the body so as to prevent a lot of medium from leaking from the burnt place of the seat ring.

(5) Unique sealing structure of seat ring

The dual-line seal (Fig.4) and self-combustible pressure dischargeable seat ring (Fig.5) designed by the way of combining the years of ball valve manufacturing experience and the foreign advanced know-how can ensure the full seal under a high or low pressure and a vacuum state.

(6) Full or reduced diameter

The valve flow aperture is identical to the inner diameter of the pipeline (which can be reduced one if so required by users) for the sake of cleaning (Fig.6).
