Eccentric Semi-ball Valve

Description1,Website:http://www.hugo-valve.com, eccentric semi-ball valve adopted eccentric wedge tight theory to reach open, close or adjust by operator device,for eccentric structure valve, when the valve opened, the ball was in the body cavity,internal flow area is wide, moreover the ball won't be washout, flow coefficient is small, when the valve closed, the trim won't be washout,the ball surface move gradually along the seat, have cut off function to realized reliable sealing. 2, used thermometal for valve and semi ball, weld different alloy steel on the ball, the seat was welded alloy bar accordingly, after special treatment, the sealing surface combined into all types performance to meet different situation demand,such as anti corrosion, wear -resisting, high temperature resistance etc .3, can realize zero leakage for noxious gas4, There is compensation dosage between seat and ball, when the seat was abrased, close the valve and rotate a little, still can achieve reliable seal to prolong the valve's longevity.Valve materials Body material : WCB,LCB,304, 316,WC9 Semi-ball material : WCB+chrome, 304+HF, 316+HF,F22a+HF Stem material :420, 304,316, F22a Seat material : 420, 304,316, F22a, PTFEApplicable standard for Valve :Design and Manufacture according to: API608 Length of Face to face : ASME B 16.10 Flange size standard: ASME B 16.5 Test and inspection standard: API608NPS : 2''-56'' ( 50mm - 1400mm )Pressure range : 150 class - 600 classDimension (150 class pressure for reference) Unit:mmNPSLDdKbFZ-Φd2''140150120.592191.64-Φ193''178190152.5127241.64-Φ194''200229190.5157241.68-Φ195''254255216186241.68-Φ226''267280242216261.68-Φ228''292343299270291.68-Φ2210''330406362324311.612-Φ2512''356485432381321.612-Φ2514''430535476413351.612-Φ2916''530600540470371.616-Φ2918''580635578533401.616-Φ3220''630700630584431.620-Φ32
