The installation direction is adjustable, the maximum pressure difference is 14bar, and the maximum displacement is 1260Kg/h
Features
Variable installation methods:
The flow direction can be changed on site by simply rotating the valve cover according to the pipeline flow direction requirements (make sure the arrow on the nameplate points downward)
| Materials | Selection | Restrictions | Installation Instructions |
| • FT14 body, bonnet: GGG40 • FTS14 body, bonnet: Austenitic stainless steel • FTGS14 body: Austenitic stainless steel • Bonnet: GGG40 • Seat: Martensitic stainless steel • Disc: Martensitic stainless steel • Other internal parts: Stainless steel | •Built-in filter, with the letter “X” after the model number •Steam breaker and steam lock device, with the letter “C” after the model number Note: The steam breaker and steam lock device is used to prevent the occurrence of basic steam lock in the system. The valve that is equipped with the steam breaker and steam lock device still has an air exhaust device. | • Design pressure (PMA): 16bar • Maximum operating pressure (PMO): 14.6bar • Maximum operating temperature (TMO): 250°C | Note: When installing, make sure the fluid flow direction is consistent with the direction indicated by the arrow on the valve body, and ensure that the float arm is horizontal so that the float can rise and fall freely and vertically. |

Additional cold water discharge capacity of the thermostatic air exhaust valve under start-up conditions
The displacement in the figure is based on the condensate displacement at saturation temperature. During the startup phase, the condensate is cold and the thermostatic air exhaust valve is open to provide additional condensate displacement. The table provides the additional cold water displacement of the air exhaust valve under different pressure differences:
