DESCRIPTION

Commodity name: Pneumatic Three-Way Ball Valve

Advantages of pneumatic three-way ball valve:

1. Different connection forms can be selected, including pneumatic flange three-way ball valve and pneumatic threaded three-way ball valve to meet different usage conditions.

2. The sealing effect is excellent. The elastic deformation of soft sealing PTFE can achieve leak-free sealing.

3. One valve has multiple functions: it can be made into an L-shaped port or a T-shaped port to achieve functions such as distribution, confluence, and diversion.

4. The pneumatic three-way ball valve is easy to install, and any port can be used as the circulation inlet of the medium without leakage.

5. It is widely used in piping systems such as environmental protection, oil products, metallurgy, steam, energy, papermaking, food, etc. to change the flow direction of the medium or achieve diversion or mixing of the medium.

Standard specifications for pneumatic three-way ball valves:

1. Design and manufacturing: GB/T12237-1989; APl608.

2. Inspection and testing: GB/T13927-1992; APl598.

3. Flange connection: JB/T79]-2-1994; ASME/ANSIB165.

4． Structure length: JD-2002

Echo device: also called limit switch, remote feedback switch signal (explosion-proof)

Solenoid valve: choose two-position five-way for double-acting, choose two-position three-way for single-acting (explosion-proof)

Triple piece: can stabilize the air source, filter, and add lubricating oil to the cylinder

Valve positioner: input 4~20mA signal to realize valve adjustment function YT-1000R
