Features of ash discharge ball valve products

1. The manual part can use steel plate pressed handles or stainless steel cast handles. The handle is equipped with a limit structure, which sets limits at the opening and closing positions of the valve. When the valve is used on critical devices, a locking hole is set on the limit block to lock the switch position and avoid misoperation. There are clear on/off markings on the handle.

2. The valve stem is forged and modulated using A182F (1Cr13) as a whole, with a hardness of HB220-250. The valve stem is connected to the handle through flat keys, splines, or square wedges, making it versatile and easy to disassemble. The valve stem is equipped with an anti blow out structure.

3. The packing of the valve is selected as braided, flexible graphite sealing ring or PTFE sealing ring, so that the valve stem can achieve reliable sealing under certain lubrication conditions.

4. According to the needs, the ball valve can be designed as an anti-static structure, with conductive springs installed between the ball and the valve stem, as well as between the valve stem and the valve body, to prevent static electricity from igniting flammable substances and ensure system safety.

5. There are various forms of sealing pairs. According to different working conditions, structures such as soft seals, hard seals, and fire-resistant valve seats can be selected; Below DN150 is the floating ball form, and below DN200 is the fixed ball form.

6. An auxiliary sealing structure can be installed at the valve seat of the ball valve, and a grease valve can be added to the valve seat and valve stem. In emergency situations, it can be temporarily sealed and the valve stem can be extended as needed to be suitable for buried laying.

2 piece ball valve flange end

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status
