• Fast sealant injection that can be removed under pressure
• The system includes ball check valves IN order to prevent the back pressure and maintain the pressure in the sealant cavity
• The mechanical spring type grade SS-304 washer is under compression and holds the plug in an equalized pressure position, thus eliminating the possibility of plug taper lock
• This system permits sealant injection while the valve is under full line pressure
• Walworth recommends that the valves be lubricated with plug IN the fully opened or fully closed position for optimum valve performance
• Quarter turn stop collar also functions as an indicator of the plug's position
• Ensures a complete sealing of the valve against leakage
• Walworth plugs are designed with an specific coating material that reduces the coefficient of friction making the valve to operate with low torque
