SpecificationGeneral purpose butterfly valve.conforms to en 593 standards.iso 9001 certified manufacturer.Wafer or lugged cast iron body.stainless steel disc and stem.ePDm or nbr seats. as2129 table e flange connection as standard. ansi‑bs16.1/5 #125/150 connection available on request.
DeSign featureS1. aGa approved for gas service. aGa certificate no. 4030 applies
to Dn50‑Dn150 valves to a maximum pressure of 8 bar (800 kPa) with an nbr seat. available to suit table e or ansi 150 flanges.
2. the operating lever is cast ductile iron for long life in all but the most corrosive environments.
3. lever handles have s/s 304 10 position notch plates and memory stop plates are also available. Gear operators have an infinite number of positions.
4. a raised key section on the liner fits into a matching keyway on the inside of the valve body to provide greater flexibility at the disc seating area and prevent liner ‘roll‑out’, a condition where the seat can come away from the body when high velocities occur or the valve is installed incorrectly.
5. the moulded seat design is easily replaced in the field, provides isolation of the body from the service fluid and acts as a gasket face for sealing.
6. the acetal bushing takes care of any operator induced side thrust loads and when combined with chevron type secondary stem seal ensures trouble free operation.
7. the webbed flange design of wafer body ensures correct and positive alignment between flanges ‑ one of the criteria for good butterfly valve operation.
8. the valve has an extended neck for insulated pipe services.
9. Pinless disc design, eliminates one less leak path past the disc.
10. valves can also be supplied with pneumatic, electric or hydraulic actuators and with all accessories such as limit switches, solenoid valves, manual override etc.
11. valves can also be supplied with the disc diameter undercut to ensure minimum torque and smallest possible actuator size for throttling or low pressure shut‑off actuated valve applications.
12. the hyflo mkv has a spherically machined disc to ensure improved sealing from valve internals under higher operating pressures. stem and bushings etc never come into contact with service fluid.
supplied as standard with either lever or gearbox.
an extra leaver, gearbox, spare seats and memory stop kits can also be supplied separately.
note: for matching bolt and nut sizes, lengths and qty’s refer to page 1.26 of tradelink industrial catalogue.
note: for service other than hvac water and aGa service please consult for compatibility of seat elastomer and disc material with service fluid.

hyflo mkv cast iron butterfly valve
before inStaLLation cHeck
1. Pipe flanges are free from weld spatter or swarf.
2. the flanges are on the same centreline and their faces are parallel.
3. the pipe internal does not contain objects that will obstruct the disc from fully opening.
4. the pipe flanges internal diameters are within the above minimum and maximum dimensions. this is to make sure the disc does clear the inside of the flange and the flange fully seals with the raised gasket face of the seat.
5. Do not weld near the valve.
6. Do not use flange gaskets or sealing compounds.
inStaLLation
1. operate valve fully before and after installation.
2. semi‑open the valve so that the disc does not protrude outside of body. this prevents damage to the disc and reduces initial torque.
3. separate pipe flanges enough to clear valve body and liner faces to prevent damage to the seat during installation. insert valve.
4. manually loose fit flange bolts and centre valve bore with pipe/flange bore.
5. open valve fully to ensure no contact between disc and pipe or flanges.
6. Progressively tighten bolts in diagonal sequence until metal to metal contact is achieved between the valve body and flanges.
7. operate valve several times to ensure no obstruction to disc travel.

DeSign featureS 1. Watermark approval to ats 5200.012 ‑ 2005, certificate no.
Wmka20022 for potable water service in valve sizes Dn50 to Dn300.
2. supplied as standard with either a lever (Dn50‑Dn150) or gearbox (Dn100‑Dn300). memory stop kits or actuators and accessories are available.
3. Distinquishable from the standard hyflo mkv valve because of the valve colour, the Watermark valve is blue, the standard valve is green with a yellow lever
4. seat design to prevent 'roll out' when high velocities occur or valve is installed incorrectly.
5. seat design is easily replaced in the field, isolates the fluid from the valve body and acts as a gasket face for seating.
6. the acetal bushing and chevron secondary stem seal ensures trouble free operation.
7. the valve has an extended neck for insulated pipe services.
8. Pinless disc design eliminates one less leak path.
9. the hyflo mkv has a spherically machined disc to ensure improved sealing from valve internals under higher operating pressures. stem and bushings etc never come into contact with service fluid.
preSSure/temperature ratingS for potable water service up to 1400 kPa (200 Psi). lugged valve suitable for full rated pressure in downstream dismantled condition, provided all installation requirements are met.ePDm seat: ‑15°c to +120°c (‑5°c to +100°c continuous)
note: for matching bolt and nut sizes. lengths and qty's refer to page 1.26. for installation instructions refer to page page 2.4. for top flange mounting dimensions to iso5211 refer to page 2.3.
note: for service other than Potable water please consult with us for compatibility of seat elastomer and disc materials with service fluid.

DeSign featureS1. the Disc diameter is undercut to ensure minimum torque and
smallest possible actuator size for throttling or low pressure shut‑off actuated valve applications.
2. Pinless Disc design eliminates possible leak path or risk of pin failure.
3. stem rention via circlip ensures stem cannot blow out if the valve is over pressurised.
4. Primary and secondary sealing features, an interference fit between seat and disc, and seat and stem, do not rely on outside flanges.
5. seat retention design minimises distortion/movement of the seat.
6. moulded double o‑rings on the seat between the seat and the flange, and seat and stem surface maximise sealing.
7. seat is not bonded to the body and is replaceable, enabling extended service life.
8. extended neck design for insulated pipe services.
9. locating holes on the body wafer essential for alignment and proper installation.
10. Disc is manufactured from 316 stainless steel for corrosion protection.
