Butterfly valves JHP 4 A standardised butterfly valve ISO / NF / API 11 5 3 9 12 9 1 10 2 Fire safe standards: • API 607 • BS 6755-2 Flange adaptation: • ISO 2084 • NFE 29203 • DIN 2501 • BS 4504 • AISI B 16.5 • JIS B 2210 4 6 7 8 13 Face to face: • ISO 5752 • NFE 29305 • DIN 3202 • BS 5155 • API 609 • MSS SP 68 Standardised mounting plate: ISO 5211
No leakage 1 Seat Leak tightness is unaffected by seat creep as the seat can move radially in its slot. 2 Bottom end cover ensuring lower stem tightness by the cover’s static seal in expanded graphite. 3 Packing system The perfect internal tightness is obtained by a conventional packing system in expanded graphite. The excellent temperature stability allows excellent static and dynamic tightness. The bearings avoid any deterioration of shaft at the packing level. Easy accessible 4 Standardised mounting plate The integrally cast plate is in accordance with ISO 5211. The actuator can be directly mounted to it. 5 Twin column construction allows easy access to the packing system without removing actuator. 6 Extended neck for easy insulation. Especially designed for isolated pipes, it allows insulation – flanges included – with easy access to the packing system. 7 Centering flange bolt locator allowing precise centering of the valve on the pipe. 8 Retaining ring with screws outside of flange sealing zone. Perfect guiding 9 Bearings Double corrosion resistant bearings on upper and lower stem. Providing low friction coefficient, high load capacity and perfect guiding of the stem. 10 Disc locating shoulder Shrunt on during assembly, it retains its position for the life of the valve and prevents displacement of disc in relation to the seat while in service. 11 Travel stop position indicator located at the mounting plate level: • The travel stop is set during assembly at 90° disc angle in order to avoid any deterioration of seat due to over-rotation of disc. • The travel stop contact against the mounting plate, taking away all stresses from the trim when overtorque occurs. • When actuator has been removed and valve is in service, the position of the disc is clearly shown. The ultimate design 12 Disc to stem pinning which allows accurate connection without any angular rotation between disc and stem. Optimized design 13 Disc With a computer optimized disc profile, the double offset design eliminates most disc/seat contact during opening. The results are: • no wear and low closing torque, • a wide open section resulting in a low headloss and a very high flow capacity value. The disc edge has a geometry which: • facilitates the connection between disc and seat during valve closure, • seat tightness guaranteed through wide area of contact. The double-offset design guarantees: • the elimination of most disc/seat contact, • a permanent alignment of disc and seat. 5
