Ghibson TT Series PTFE Seated Butterfly Valve, are engineered to excel in the most demanding environments.
The PTFE body seat, is engineered with a thickness ranging from 2.5 to 3 mm. This design, varying in thickness according to positioning, guarantees unparalleled reliability even in the shaft area. Reinforcing this design, two silicon half rings amplify elasticity, ensuring consistent operation even at elevated temperatures.
The series comes with a wide range of material combinations, and whether you choose stainless steel (AISI316), HASTELLOY®, DUPLEX®, SUPERDUPLEX®, INCONEL®, or others, the disc's construction guarantees resilience under various conditions. Additionally, stainless steel discs coated with HALAR® or PTFE offer enhanced protection and performance.
Crafted from AISI316 stainless steel, the standard shafts deliver steadfast performance, with Monel® and other material options available upon request. Belleville washers play a crucial role in maintaining a secure seal on the disc's upper plane, further fortifying the valve's integrity.
Leakage concerns are eliminated through the implementation of a double packing mechanism. Featuring an FEP-coated FKM O Ring coupled with a PTFE C-ring, this combination ensures zero leakage along the shaft. In the TT-valve series, the PTFE lining extends beyond the FEP-coated FKM O Ring, assuring that the fluid never comes into contact with the metal core of the disc.
The Ghibson TT Series boasts a PTFE lining that envelops the shaft, extending beyond the FEP-coated FKM O Ring. This innovation ensures that fluid remains isolated from the metal core of the disc, minimizing potential chemical reactions and enhancing the valve's lifespan.
In case your media is abrasive and also corrosive, or reaches high temperatures (max 190°C), TT is the obvious choice due to the high-temperature silicon-backed fluoro-polymer seat, guaranteeing high performance even in demanding applications.
