Triple Offset Valve (Metal & Graphite Seat / Solid Metal Seat)
When Triple offset Design is introduced to the market, Triple Offset Design (TOD) overcomed the limitations of Double Offset Design. Double Offset Design is prone to excessive wear from friction and abrasion between sealing components. To eliminate problems, TOD features a special sealing mechanism that consists of an inclined conical disc and a laminated seat. The unique characteristics of TOD are low torque operation, broad sealing width and bi-directional tight shut-off.
