Triple Eccentric Metal Seated Butterfly valves Specification of Triple Eccentric Metal Seated Butterfly Valve Triple eccentric metal seated butterfly valves are widely used in plants and high pressure piping system. The metal seat shall be consisted of laminated seat or solid seat. The valve shall be capable of bi-directional flow bubble tight shutoff at full rated pressure. TYPE NUMBERING SY AV-TMW Triple Eccentric wafer type metal seated butterfly valves. AV-TML Triple Eccentric lug type metal seated butterfly valves. AV-TMF Triple Eccentric flange type metal seated butterfly valves. STANDARD COMPLIANCE The face to face dimension shall be in accordance with API9, ISO52, DIN 3203, MSS-SP-68, JIS F74, JIS B2032, KSV74. Fire safe design shall be in accordance with API7, 6FA and BS Triple eccentric design principle Metal seated high pressure butterfly valves provide bi-directional bubble tight shut off which achieved by introducing state of the triple eccentric disc geometry. The valve shaft is off set against the seat and the centre line of the valve body respectively. The seating edges are machined with a continuously changing slope from an angle on top of the oval seat ring to an angle at the opposite side. This geometry ensures that the seat ring stays clear of the seat except at the final shut off position which results long life seat. CENTER LINE SEAT CENTER LINE VALVE CENTER LINE CENTER LINE PRODUCTION RANGE : mm (2inch) ~ 0mm (inch) End connection ANSI B16.5, 16.47 Class LB-0LB Working temperature : -3 to +815 Working pressure : Maximum 2psi(156 kg / ) APPLICABLE FLANGE ANSI B 16.5, 16.47, LB-LB-LB-0LB, BS 3293, DIN1, KS/JIS 5K, 10K, 16K, 20K, 30K, K, 63K Metal to metal seat Various disc seals are available to comply with each temperature and pressure service applications. Solid metal seals are often used for temperatures above 510 C and up to 815 C or low temperature service. The laminated metal seal consisted of stainless steel with intermediate material of graphite or ceramic fiber layers is used widely. The laminated seal is secured to the disc with a bolt-on stainless steel clamp ring, and easily accessible for replacement. The graphite laminated seal Ring is suitable for tempertures between - C and 0 C in general. The seal leakage meets API 598 or API 6D. The solid metal seating valve can be operated in a temperature range of -3 C to +815 C. Valve for cryogenic application shall be provided with extended stem.

Triple Eccentric Metal Seated Butterfly Valves CLASS 0LB FLANGE TYPE How to Install Butterfly Valve Centering & Flanging of Valve 1. Spread both flanges enough to allow the valve with disc in closed position. This prevents the damage of disc and seat during installation. CORRECT WRONG Aligning of Flange Gaskets 2. Flange gaskets should be positioned aligned with valve bore. Pipe misalignment may cause interference between disc edge and flange face, creating leakage and excessive torque to open valve. CORRECT WRONG 310 2 3 TAPE N M N - Z Aligning of Flange bolts 3. Insert bolts throgh the two upper pipe flange holes to rest valves on during installation. Disc should be in full open position after flange alignment and before evenly tightening flange bolts. 3 0 3 430 4 515 CORRECT WRONG 430 4 95 4 1 0 4 4 5 6 685 130 4 4 Bolts Tightening 2 0 0 530 0 0 0 6 5 730 792 7 9 843 877 1 4. Disc in fully closed position may causes seat distortion and excessive toque in initial operation. Tighten the flange bolts evenly to prevent the leakage between flange and valve. 3 0 8 834 9 0 9 7 1013 2 ACE VALVE PRODUCT GUIDEBOOK TM-10 ACE VALVE PRODUCT GUIDEBOOK TM-11
