The TLV L21S is used to discharge condensate and air from steam systems. It is suitable for steam mains, tracing lines, dryers, heaters and light process equipment.
The L21S uses an X-element that responds to temperature. It opens to discharge air and cooler condensate, then closes as the temperature approaches the saturation temperature of the steam.
The standard TLV L21S has a maximum operating pressure of 2.1 MPaG and a maximum operating temperature of 235°C.
The L21S provides excellent air venting, compact high-capacity performance, rugged construction, reliable condensate discharge and convenient cleaning and maintenance.
Please confirm the connection size, connection type, inlet and outlet pressure, operating temperature, condensate load, installation orientation and application conditions before ordering.
