Overview

Pneumatic four-way threaded ball valve automation four-way valve $r $n four-way ball valve only requires the operation of a wrench or actuator to rotate the ball 90 degrees, and can switch the flow direction of two media simultaneously, which is convenient and fast, achieving the effect of one valve for multiple purposes. The valve core and visible neck material are made of austenitic stainless steel, and the valve seat material is made of PTFE, which can achieve good corrosion resistance and extend the service life of the valve.

Pneumatic four-way threaded ball valve, automated four-way valve

This four-way directional ball valve can switch between forward and reverse water supply with one valve. Every 90 revolutions, the water supply mode switches once. Previously, four valves were required, with valves 1 and 4 open and valves 2 and 3 closed during water supply; When supplying water in reverse, valves 2 and 3 are open, and valves 1 and 4 are closed. Now, a four-way ball valve is used as a replacement, which is easy to operate.

advantage:

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 forged and modulated with 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, with high versatility and easy disassembly and assembly. 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. A grease injection valve can be added to the valve seat and stem for temporary sealing in emergency situations, and the stem can be extended as needed to be suitable for underground installation
