Double-Acting, Air-Operated Valves

Series BAT � heavy-duty 2-way globe style valves for corrosive & ultra-pure liquids � Requires Compressed Air to Open and Close

Formerly Series EAT

Series BAT air shutoff valve

Plast-O-Matic Series BAT globe-pattern air operated valves are ideal for handling pureliquids, chemicals, acids, and caustics where high flow and visual verification are important.

Features:

  • Pressure balanced PTFE shaft for ultra-smooth, non-sticking operation.
  • Clear acrylic cylinder for visual verification of valve position.
  • Fail-Dry� safety feature.
  • 1,000,000 cycle design,
  • Low pressure drop with high flow rates; pressure or vacuum service.
  • Bubble-tight sealing.
  • Manual set throttling limit stop available.

Operation

阀门自动opene磁盘或主要密封d or closed with standard shop air or hydraulic power and the use of a 4-way solenoid valve. The valve has a piston attached to the main PTFE shaft (also known as the "stem"). Air (or hydraulic) is applied on top of the piston to close the valve, and applied to the bottom of the piston to force it up, lifting the disk off the seat and thus opening the valve. The amount of air pressure required depends upon the liquid line pressure present in the valve. Operation requires a 4-way air solenoid valve to control the air or hydraulic pressure used. It is recommended to regulate the air pressure to 60 - 80 PSI. The air should be filtered and lubricated for longer valve life.

A minimum of 20 PSI air pressure (25 PSI for 1", 1�" & 2") is required to operate the valve at liquid pipeline pressures up to 25 PSI. As liquid process pressure in the pipeline increases, the minimum air pressure required to open or close the valve increases as well. The maximum pipeline pressure the valve will open or close against is 125 PSI.

In situations where air pressure is not available, water pressure can be used so long as the pressure available is sufficient to actuate the valve. If hydraulic media is not clean, a filter should be used.

Valves should be mounted upright for best results and less strain on piping. Flow direction is indicated and should be adhered to for best results.

The Fail-Dry safety feature is a patented Plast-O-Matic design whereby the liquid seals and air pressure seals are separated by a vent, which will give indication of a valve problem before a system shutdown is necessary.For a complete explanation of the Fail-Dry system, please click here.

Sizes & Materials

Series BAT is available in 3/4", 1", 1�", 1�" and 2" pipe sizes. Valve body is Geon� PVC. Cylinder walls are high-strength acrylic. Shaft is PTFE. External fasteners are stainless steel. Elastomeric seals are choice of Viton�, EPDM, or Buna-nitrile. Piston head seals (not wetted) are Buna-N. For other materials, please contact the Plast-O-Matic Technical Department at 973-256-3000 or e-mail info@www.trynanohooks.com

Connections, Pressure Ratings

Standard connections are NPT. Optional connections are socket or flanged. Air inlet connection is 1/8" NPT. Maximum air pressure is 100 PSI. Minimum air pressure required to close the valve is 15 PSI (30 PSI for 1/2", 20 PSI for 1�" & 2"). Use of an air flow rate valve may be required to prevent water hammer, depending on your application.

Maximum liquid line pressure is 125 PSI. There is no minimum liquid line pressure required for the succesful operation of Series BAT.

Design:

Series BAT automatic valves require air or hydraulic pressure to open and close. Three o-rings seal against a pressure balanced PTFE shaft. This, in conjunction with a poppet seat at the valve orifice, results in a non-sticking design. The piston head seals against the acrylic cylinder wall with two o-rings.

Throttling Option:

A very simple and inexpensive throttling limit stop to control flow is available for Series BAT. This is adjusted in the field to a set opening and the valve will always re-open to that point. If the line pressure remains constant, the flow will then remain constant.

Please Note:The air pressures required for opening and closing, listed above, are not complete for all liquid line combinations. For example, the BAT150EP-PV requires 35 PSI air to close against 100 PSI liquid line pressure. The table above is not complete simply because it would be too cumbersome for this website. For more precise data, please refer to the catalog, orclick here for the .pdf file.

To order with throttling limit stops, add "LS" to part number, after the seal material.
Example: BAT075V-LS-PV.
For Buna-nitrile seals, replace "V" or "EP" with "B". Example: BAT075B-PV
Maximum air pressure rating is 100 PSI/6,90 BAR.
