Centric API609 Butterfly Valve PTFE Lined Self Lubricated Shaft Bear ATEX Wafer Type Butterfly Valve
Centric Butterfly Valves
PTFE lined butterfly valve model IVTFE provides an optimum solution to the corrosion problems encountered by the chemical and process industries with conventional butterfly valves. The PTFE seat liner covers the entire wetted surface of the body and extends around the flange faces thus eliminating the possibility of any media contact with the body.
The fully circular backup elastomer and live loaded disc shoulder sealing ensures bubble tight closing of the valve with zero shaft leakageThe valve is adaptable for ON / OFF as well as control duty and can be fitted with actuators and accessories as required to meet the specific duty conditions.
The body is designed to fit between all international flange standards.
2. Bi-directional valve with sealing capability to hold rated shut off pressure in either direction.
3. Circularly moulded back up elastomer provides uniform contact pressure over the entire seat without losing shaft bore shape, ensuring bubble tight closure every time.
4. Unique triple sealing system for shaft sealing, eliminates any fugitive emission or secondary leakage.
5. Self lubricated shaft bearings (PTFE coated stainless steel) for both drive end and non-drive end shaft ensures minimum bearing friction torque.
6. Live loaded disc shoulder sealing arrangement through pusher and disc springs in both top and bottom shaft bores, acting on PTFE liner ensures leak free mechanical stem seal.
7. Back up elastomer standardised in Viton to ensure excellent corrosion protection and maximum temperature resistance against media fumes and higher temperature.
8. Disc springs and fasteners standardised on corrosion resistant stainless steel to ensure long service.
A choice of exotic metallurgy for the disc, to meet any type of aggressive media.
9. Choice of liner materials of virgin PTFE or filled PTFE.
10. Low operating torque enables selection of smaller size actuators.
11. Perfect adaptability for conversion from manual to actuated operation due to standardised top flange.
Conformity to codes and standards:
1.Complies with the requirements of European Pressure Equipment Directive PED 97 / 23 / EC
2.Complies with the requirements of ATEX 94/9/EC
