Page 5: 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 6: Operation
Operation Principles of air and condensate discharge: 1. Air and Cold Condensate Discharge at Startup At startup, before steam is supplied, the system is cold and the bimetal air vent strip is contracted, holding the float off the valve seat. This allows for the rapid discharge of air and cold condensate through the valve when steam is first supplied to the system. -

Options With Blowdown Valve (TLV-BD2) Always wear eye protection and heat-resistant gloves when operating CAUTION the blowdown valve. Failure to do so may result in burns or other injury. When operating the blowdown valve, stand to the side well clear of the outlet to avoid contact with internal fluids that will be discharged. - Page 21 BD2 Blowdown Valve Operation The BD2 valve is in the closed position when the BD2 is shipped from the factory. Before attempting to operate the BD2, reconfirm that the BD2 valve is still in the closed position.
