| Long usage: | The TIPBV`s valves provides the features that engineers and users have requested and are included in the AWWA C504 and C516 Butterfly Valve standards. The TIPBV`s valves is designed to provide long life and trouble-free performance. If maintenance becomes necessary the valve is also designed for easy field service. The shaft seal incorporates V-type packing which is easily replaced in the field without removal from the line. Adjustment of the resilient seat is easily performed with a torque wrench as compared to epoxy filled seats that require special equipment and materials or bonded seats that cannot be replaced or adjusted in the field. |
| Low-cost environmental solution: | With TIPBV valves can easily be adapted to comply with evolving emissions regulations. |
| Simple mechanism: | To meet customer's ease of replacement and best cost performance the TIPBV uses the most economical valve design and structure |
| Body: | The valve body shall be cast iron ASTM A126 Class B or Ductile Iron ASTM 536 65-45-12 narrow body design. Body thickness shall be in strict accordance with AWWA C504 latest revision where applicable. The valve shall have a clear inside diameter. |
| Disc: | The valve disc shall be constructed of ductile iron ASTM A536 with 316 stainless steel disc edge. The disc shall be free of hollow chambers. All surfaces shall be capable of visual inspection. Disc and shaft connections shall be made with stainless steel pins that do not generate a leak path across the disc. Cast iron discs or alloy cast iron are not acceptable. Head loss analysis and Cv values shall be provided with the tender submission and will be taken into consideration by the city or appointed engineers during the tender analysis. All valves must be shipped with valve discs 2-3 degrees open. |
| Corrosion resistant shaft: | All valve shafts shall be one piece or two piece stub-shaft type 17-4PH ground and polished stainless steel. The shaft diameter shall meet the latest requirements of AWWA C504. Carbon steel shafts with stainless steel journals are not acceptable. The lower valve shaft shall incorporate a dual thrust bearing to permit valve positioning in a 360 degree circumference. The valve shaft shall be capable of horizontal mounting. |
| Rubbe seat: | All seats shall be of natural or synthetic rubberrubber seats shall be clamped mechanically secured or bonded to the valve body. Valve seats shall be field adjustable around the full 360 degree circumference under full pressure without removal of the valve. |
| Disc sealing ring: | T type sealing rubber ring integrate moulded form high precisionbidirection sealing |
| EPDM seal: | The Butterfly Valves shall be constructed from EPDM seals suitable for water applications. |
| Renewable seal: | Sealing ring can be respectively maintained and replaced after accidental damageThis replaceable Seal ring allows for a dependable tight seal and a longer service life. |
| Shaft seal: | Self-sealingY-type or V-type rings provide excellent sealing low abrasion and long service life when fluid pressure increases |
| Bearings: |
All valves shall be fitted with sleeve type non-me |
| Coatings: | All valves shall be coated with minimum 8 mils DFT externally with NSF 61 epoxy coating and minimum 8 mils DFT internally coated with NSF 61. Fusion bonded NSF certified coatings are acceptable. color and coating manufacture is to be specified on the drawings. |
| Lifting lugs: | All valves shall incorporate four tapped holes strategically located on each flange outside diameter. Two hoist rings shall be supplied with each valve. The hoist rings shall be capable of lifting the valve together with the actuator as a single unit. |
| Locking device: |
Available in single or bidirectional configurations the overtravel stop device prevents disc from rotating into the wrong quadrant while maintenance is performed on the disc repair and enhancing safety. |
| O-ring: | Prevent end from leakage efficiently |
| Self-lubricating bearing: | Stainless steel backed PTFE bearing is designed for superior lubrication with low maintenance. |
| Shaft packing: |
All shaft seals shall be of the self-adjusting chevron “V” type shaft seals. The shaft seals or packing shall be retained with an external adjustable packing gland. The packing shall be field replaceable and adjustable. Removal of the actuator will not cause the packing to leak and the packing shall remain retained. Leakage of the upper packing will not pressurize the ba |
