Basic information:

- Weight: 992 lbs. (450kg)
- Dimension: 62”W x 35”D x 84”H (1560x875x2106mm)

The STB Portable Valve Grinding Table has a reinforced frame manufactured of steel and aluminium. One can easily make manual adjustments of the operating arm (laterally and vertically) over the table producing high precision results.

The valve grinding table has two working points; for example on the first point one can prepare a valve for a job while simultaneously grinding a valve or a wedge.

The legs and table top are manufactured of stainless steel resistant to scratch damage.

A benefit with the STB is that one can build it in modules to fit one’s specific needs and expand the capabilities as those needs change. Examples of options are listed below:

- A variety of tools for cutting, milling, grinding and lapping etc.
- A control unit with electric motor for adjusting the operating arm.
- A control panel to adjust the speed and direction on the grinding motor.
- A time controller so you can set a time schedule on the grinding work.
- A 16 ° tilt table for gate valve wedges etc.

Additional options are available on request.
