الوصف

A secondary metal seal designed to maintain positive shutoff in case of fire damage to the PTFE seal. Double-offset design and geometry of the valve and seal combine to ensure a uniform 360° 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 150 lb and 300 lb in sizes up to 600 mm with sizes above on request. The Metalseal design lends itself for use on higher temperatures and abrasive services 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 and tungsten carbide. Features and benefits: - Double-eccentric action moves the vane into and out of the seat with minimum wear and seating torque, giving longer seat life and reduced overall valve torque. - Sealing ring is easily replaceable. - The vane’s streamlined design improves the flow line and reduces the head loss shutoff pressure up to 100 bar; extensive range of body and trim options - Capable of dual purpose of modulating control and shutoff; secondary metal seal maintains shutoff in accordance with BS 6755 Part 2 in case the primary PTFE seal has been destroyed in a fire. - Seat design enables stable tight shutoff performance, both in direct and reverse flow conditions. - Wafer, lugged and double-flanged bodies are available. - Full and reduced bore sizes
