Double offset design and geometry of the valve and seal combine to ensure a uniform 360º seal contact in the closed position. The double eccentric action moves the disc with the minimum of wear and seating torque. Fully rated to ANSI class 150lb and 300lb in sizes up to 600mm with sizes above on request.
The Metalseal design lends its self for use on higher temperatures and abrasive service where a PTFE seal would not be acceptable. ANSI Class IV leakage is achieved. The valve can be supplied with a range of hard surface deposits such as hard Chrome plating, Stellite & Tungsten Carbide.
