OS&Y Root Valves – M5K, M5AK, and M5YK

1 Anderson Greenwood Gauge Valve CatalogBlock and Bleed, Multi-Port and OS&Y Valves 1998, Rev. 1999 Anderson Greenwood reserves the right to change product designs and specifications without OverviewM5K Gauge ValveThe M5K gauge valve is a multi-portedroot/primary instrument isolation valve,designed for use with gauge mountingsand other pressure instruments in refineries and chemical plants. The M5K facilitates installation of multiplemeasurement devices without additionalpenetrations of the main M5K is available in metal seat designwith integral seat, or with various replace-able, roddable soft seats (1/4-inch[ mm]diameter orifice). m5ak Gauge ValveThe m5ak gauge valve is a multi-portedroot/primary instrument isolation valve,designed for use with gauge mountingand other instrument ties in refineries andchemical plants.

2 Additional penetrations of the main piping are not m5ak is available with a variety ofreplaceable, roddable, metal or soft seats,with3/8-inch [ mm] diameter unique metal seat design offers bubble-tight shutoff with straight-throughflow Gauge ValveThe m5yk gauge valve is a versatile, dualoutlet valve for use in gauge mounting oras root /primary isolation valve in differen-tial pressure transmitter construction of body and OS&Ybonnet allows installation and replace-ment of Valves in orifice taps withoutremoval of bonnet valve is designed for safety, service,and economy. The long-necked inlet pro-vides room for insulation and the dual1/2-inch NPT outlet ports provide an extraoutlet for bleeder or sampling m5yk is standard with 1/4-inch[ mm] integral seat. Available with seat insert and stem ball of selected metals to match process and Benefits Four-bolt outside screw and yoke(OS&Y) bonnet provides easy accessto the packing gland.

3 Stem threads arecompletely isolated from the process. Protective stem bellows and cap protects against atmospheric contami-nation and increases the valve and cap help contain stemlubricant (unlike most OS&Y designs)which reduces possible thread galling. Compact designrequires minimumspace for operation and valve weight improves strengthat the process connection and reducesinduced bending moments. Multi-port outletmeans fewer fittings,fewer leak points, and reduced installa-tion cost. Standard SS investment cast yokeimproves valve life by resisting corro-sion. Material used is A351-CF8M. Single-piece yoke designmeans bind-ing of the stem does not occur as withOS&Y bonnets that use bolts to holdand position the yoke. GRAFOIL or Teflon flange gasketringoffers wide compatibility to processfluids without deteriorating flange gasket(bonnet-to-body).

4 Non-rotating plug design ( m5ak )pro-vides bubble-tight valve closure withoutmetal seat galling and low seatingtorque. Free-swiveling ball end stem design(M5K, m5yk )makes for bubble-tightvalve closure without seat galling. Integral hard back seat (M5K, m5yk )protects against stem blowout and provides alternate sealing for longerpacking life. Replaceable, roddable soft seatdesign (M5K, m5ak )can be specifiedwith the time-proven bubble-tight seatwith a fully roddable, bi-directional for the M5K - soft seat orificediameter is 1/4-inch [ mm] and stan-dard for the m5ak is 3/8-inch [ mm].OS&Y root Valves M5K, m5ak , and M5 YKRoot Isolation Valves with Outside Screw and Yoke, Bolted Bonnet Construction M5 AKM5K-LM5 YKAnderson Greenwood Gauge Valve CatalogBlock and Bleed, Multi-Port and OS&Y Valves 1998, Rev.
