Pneumatic Forged Steel Four Way Multi-Type Floating Ball Valve

Product Introduction

Pneumatic Four way ball valve can change the flow direction of medium,when rotate 90 degree,the flow direction can be changed,therefore,it can replace several through-way type ball valves,and operation is very convenient,It can be widely used for the pipelines of petro,natural gas,chemistry,electricity,water supply,metallurgy,food.,

industrial sectors.

Product Features

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 open and closed positions of the valve. When the valve is used on a critical device, the limit block is equipped with a locking hole to lock the switch position and avoid misoperation. There are obvious open and close markings on the handle.

2. The valve stem is connected to the handle through a flat key, spline, or square groove, which has strong versatility and is easy to disassemble and assemble. The valve stem is equipped with an anti blowout structure.

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

4. As needed, ball valves can be designed with anti-static structures, with conductive springs installed between the ball and valve stem, as well as between the valve stem and 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 in the form of a floating ball, and below DN200 is in the form of a fixed ball.

6. An auxiliary sealing structure can be installed at the valve seat of the ball valve, and a grease injection valve can be added to the valve seat and stem for temporary sealing in emergency situations. The stem can also be extended as needed to be suitable for underground installation.
