Ball valve floating ball type, 2 piece construct, full bore, DN50, PN16, flanged end, flange with raised face, valve material stainless steel: body and bonnet AISI321, ball and stem AISI321, seat PTFE, the ball valve is manual operated with handle lever. AISI321 is better than normal stainless steel such as AISI304, AISI321 include special chemical element “Ti” which is better for corrosive medium .
Ball valve, type trunnion mounted ball with upper stem supported, class rate 300Lb, lockable gearbox with handwheel operation, split body ( two piece ) construct, which is generally used for middle and low pressure condition construct. the valve is full bore type, which provide excellent flow rate. Flanged end raised face, flange finishing with serrated face. fire-safe design, with anti-static device spring supported stainless steel small ball, also is blow-out proof stem design. The ball valve is double block and bleed function design. and stem & seat grease injection fitting. With bleed plug and vent plug. Main part material body and bonnet ASTM A216 WCB, ball ASTM A182 F316, seat ASTM A182 F316, prime sealing NYLON, stem SS A276 316, seat spring Inconel X-750, packing graphite, bolt and nut ASTM A193 B7 & A194 2H.
