SFT44 SFT46 Series Float Steam Trap

Maximum pressure difference 32bar, maximum displacement up to 31000Kg/h

 

Features

The parallel upper and lower double valve discs are subjected to the same surface pressure inside the valve body, requiring only a small force to open. Even if the volume of the float is reduced, the large displacement function can still be ensured.

An anti-erosion baffle is installed in the valve body to prevent steam flow from hitting the float.

Built-in automatic air exhaust device, quick start, no air blockage, good performance in exhausting non-condensable gases.

Product Description
Materials Selection Restrictions Installation Instructions
• SFT44 body, bonnet: carbon steel
• SFT46 body, bonnet: austenitic stainless steel
• Valve seat: martensitic stainless steel
• Valve disc: martensitic stainless steel
• Other internal parts: stainless steel		 •Steam lock breaker, with the letter “C” after the model number
. Note: The steam lock breaker is to prevent steam lock from occurring in the system. The valve that is equipped with a steam lock breaker still has an air exhaust device.		 • Design pressure (PMA): 40bar
• Maximum operating pressure (PMO): 32bar
• Maximum operating temperature (TMO): 343℃		 Note: During installation, 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 in a horizontal position to ensure that the float can rise and fall freely and vertically.

Wafer Check Valve

Working principle

A check valve is a valve that automatically opens and closes the valve disc depending on the flow of the medium itself to prevent the medium from flowing back. It is also called a non-return valve, one-way valve, reverse flow valve, and back pressure valve. It is a type of automatic valve.

Wafer check valves are designed to be installed between flanges and are suitable for various fluids in process pipes, hot water systems, steam and condensate systems.

Note: Wafer check valves are not suitable for applications with severe pulsation, such as compressor outlets.
