Style 350 Ultraseal valves are permanently lubricated and provide bidirectional, bubble-tight shut-off and zero leakage to the atmosphere. Flow capacity requirements meet applicable sections of ANSI B16.33 or B16.38 and each valve is extensively tested to ANSI B16.33 requirements prior to shipping.
