Page 6: Checking The Piping
4. Have isolation valves been installed at the inlet and outlet? If the outlet is subject to back pressure, has a check valve (TLV-CK) been installed? 5. Is the inlet pipe as short as possible, with as few bends as possible, and installed so the liquid will flow naturally down into the product? 6. -
Page 7: Operation
Operation Principles of air and condensate discharge: 1. Initial Air and Cold Condensate Discharge At startup, before steam is supplied, the trap is cold so the X-element is contracted and the air vent valve seat (A) is open. This allows for the rapid discharge of air through the air vent valve (A) and cold condensate through the orifice (B), when steam is first supplied to the system. - Page 8 4. Closed Position When the condensate flow rate decreases, the float falls as condensate is discharged, closing off the orifice (B). A water seal is maintained at all times over the orifice (B) to prevent steam loss. Note The high steam temperature causes the X-element to expand, keeping the air vent closed. Steam Condensate...
