Pressure Balanced Plug Valves (API 6D)
|
|
Super-H Pressure Balanced Plug Valves incorporate the unique pressure-balancing
system and on-line maintenance feature, which enhances valve reliability and reduces
operating torque.
|
|
The plug and body seating surfaces, which are lapped and matched together, are not
exposed to the line fluid, and thus confines corrosion and erosion to less critical
areas. Sealing is further enhanced by specially developed plug sealants charged
around the seating surfaces.
