Model M5K/M5AK/M5YK

Gauge ValvesAnderson Greenwood

Root isolation valves with outside screw and yoke, bolted bonnet construction for pressures up to 6,000 psi (414 barg)

M5K series gauge valves are designed for use with gauge mountings and other pressure instruments in refineries and chemical plants. The M5YK can also be used as a root/primary isolation valve in differential pressure transmitter installations.

  • True 4-bolt bonnet design provides easy access to the packing gland. Stem threads are completely isolated from the process.
  • Protective stem bellows and cap protects against atmospheric contamination, increases valve life and helps contain stem lubricant, reducing thread galling.
  • Compact design minimizes space requirements. Lower valve weight improves connection strength and reduces induced bending moments.
  • Multi-port outlet means fewer fittings, fewer leak points and reduced installation cost.
  • Standard CF8M investment cast yoke resists corrosion, increasing valve life.
  • Single-piece yoke design eliminates stem binding.
  • Widely compatible graphite or PTFE flange gasket ring minimizes bonnet-to-body gasket deterioration.
  • Free-swivelling ball end stem design (M5K, M5YK) or non-rotating plug design (M5AK) provide bubble-tight valve closure without metal seat galling and low seating torque.
  • Integral hard back seat (M5K, M5YK) protects against stem blowout and provides alternate sealing for longer packing life.
  • Optional replaceable soft seat design (M5K, M5AK) provides bubble-tight seat with a fully roddable, bi-directional flow.
