Heavy-duty stainless steel coil-spring design ensures positive closure. Working Pressure, Non Shock (PSI) Cold working pressure (CWP): 150 psi up to 180°F Saturated steam (WSP): Not suitable for steam service Pictured Model T-50NL Cut-away Pictured Model T-50NL Side view Pictured Model T-50NL • Third-party tested and certified in compliance with U.S. Federal Public Law 111-380. • End connections conform to ANSI / ASME B1.20.1 • Not suitable for applications requiring an ASME-approved relief valve.

Mark the position of the screwdriver slot in the disc (Part #3), in relation to the body (Part #8); Using a permanent marker, make a reference mark on the top edge of the body, at either end of the slot. 3. With a large flat-blade screwdriver, turn the disc clockwise to INCREASE the relief pressure. One complete 360° revolution equates to a 25 p.s.i. increase: 75 p.s.i. factory setting plus three complete revolutions from the reference mark attains the 150 p.s.i. setting. 100 p.s.i. factory setting plus two complete revolutions from the reference
