Adams invention of the triple eccentric valve, also known as triple offset design, utilizes an inclined conical metal sealing system. This allows Adams to continuously meet critical requirements with reliable performance in applications as diverse as high temperature, cryogenics, water transmission, hydro-power, hazardous gases, emergency shut-down and nuclear plant safety systems.
The TX3 is a high performance triple offset butterfly valve capable of closing with zero leakage. The precision seat and seal are machined at an offset angle creating even seat loading around the entire seat ring and eliminating rubbing between the seat and seal during opening and throttling. This design provides repeatable long-lasting zero leakage shut-off.
