Standard: api609, mss sp-67, bs5155, en593 Features: 1. For 224 lug butterfly valve, patented design of clamping between body bulge and seat groove ensures a equal force to valve stem and also replaces the traditional vulcanized seat with changeable seat for end of pipe using. 2. Stainless steel blow-out proof ring, work in whole life of the valve. 3. Unique groove on top flange getting rid of wetness under actuator. 4. Low torque figures reduce cost for actuator and ensure longer life Size range: dn40 to dn2000 Pressure rating: full vacuum to 20bar Flange accomodation: en1092 pn10/pn16 & ansi 125/150 & bs10 table d/e & jis 10k/16k Face to face: en558 series 20 Body: cast iron, ductile iron, carbon steel, stainless steel Disc: ss201, ss304, ss316, ss316l, aluminium bronze, hastelloy, dual steel, super dual steel Seat: nbr, epdm, oil & acid & alkali resitant viton-a, steam resitant viton-b, hypalon, ptfe Operation: hand lever, gear box, pneumatic actuator, electric actuator Negotiate
