1/2 in 2-way f-NPT Globe valve


Two-way, Globe, 1/2 in, (Female) NPT, 2.9 Cv, Water or Glycol or Steam

  • Product Info
  • Literature


Used for two-position or modulating control of steam and water and glycol solutions (to 50 percent concentration) in heating or cooling systems.


  • Sizes range from 1/2 to 2 inches.
  • Direct and reverse acting
  • High pressure steam models with stainless steel trim
  • Spring-loaded, self-adjusting packing.
  • Stainless steel stem prevents corrosion.
  • Valve designs provide equal percentage characteristics of flow for close control of water, and linear characteristic of flow for close control of steam or chilled water.
  • Valves utilize direct mounting, electric or pneumatic linear valve actuators; Q5001 linkage with Modutrol Motor; or Q5020/Q5022A linkages with direct coupled rotary actuators to operate the valve.
  • Not suitable for combustible gases.
