Maximum pressure difference 21bar, maximum displacement up to 64400Kg/h
Features
Balanced double valve seat design, small size and large displacement can better demonstrate its superiority in extra-large displacement occasions.
An anti-erosion baffle is installed in the valve body to prevent the steam flow from hitting the float.
| Materials | Selection | Restrictions |
| • Valve body, valve cover: carbon steel, stainless steel • Valve seat: martensitic stainless steel • Valve disc: martensitic stainless steel • Other internal parts: stainless steel | •Built-in vacuum breaker (add VB after the model number) •Inlet with filter (add X after the model number) •Outlet with stainless steel check valve (add CV after the model number) | • Design pressure (PMA): 40bar • Maximum operating pressure (PMO): 21bar • Maximum operating temperature (TMO): 343℃ |
| Installation Instructions | ||
| Note: When installing, make sure that 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 vertically. When the displacement is close to the maximum displacement of the steam trap, it is recommended to increase the size of the drainage line to solve the blockage of flash condensate at the outlet of the steam trap, thereby reducing the back pressure of the steam trap. When determining the size of the drainage line, the pressure of the condensate system should also be considered. | ||
