For general requirements of the Type 653 valve, refer to Appendix A, Product Specifications,
page 23. Specific requirements of the available flange types are provided in Appendices B

Setup
MKS products are designed and tested to provide the highest degree of safety attainable. To use
your MKS valve safely, you must always conform to the following instructions:
Warning
!
The moving parts in the valve create a risk of personal injury
until the valve is securely incorporated into a system. To
avoid injury keep all objects away from any valve opening.
•
Do not insert objects into openings where contact with moving parts is possible.
•
Isolate the equipment from any electrical or pneumatic power supply before handling the
valve.
The Type 653 valve may be mounted in any position, but the PUMP label must be oriented
toward the pump. Provide proper clearances for valve removal, as routine cleaning may be
necessary due to buildup of process contaminants. Refer to Figure 1, page 9, for outline
dimensions of the valve.
Note
All dimensions listed in this manual are referenced in inches with the
equivalent units of measure (mm) listed in parenthesis.
