Section II: Installation and operation 

of the POLYSTOPP

 10" Valve 

 

1.0 Introduction 

The POLYSTOPP

 10" Valve is a full-opening temporary valve used with TDW drilling or tapping machines and 

SHORTSTOPP

®

 II plugging equipment. It is recoverable after the tap is complete and a completion plug is set in 

the TDW SHORTSTOPP

®

 or POLYSTOPP

® 

fitting. 

1.1 Site Preparation 

The POLYSTOPP

 10" Valve matches ANSI Class 150 bolt patterns.  

The compact design of the POLYSTOPP

 10" Valve minimizes drilling machine boring bar length required to 

complete the tap.
