High Pressure and Temperature Globe Valves
High pressure and temperature globe valves are steel valves whose disc moves perpendicular to the flow and presses onto the seat, so they can handle both shut-off and flow throttling. Although the change of direction inside the body increases the pressure drop, the flow can be set precisely by the disc position.
Cast steel types are made to API 623 and BS 1873 in DN50–DN300, from Class 150 to Class 1500, flanged or butt-weld. Forged steel types are offered to API 602 in 1/2″–2″ sizes for Class 800 and Class 1500 with socket-weld, NPT threaded, butt-weld and flanged connections.
Main Applications
- Manual flow setting on superheated steam lines
- Boiler feedwater bypass lines
- Throttling at heater and exchanger steam inlets
- Steam and condensate drain points (forged type)
- Shut-off on petrochemical process lines

Which construction? Choose forged steel on small-bore steam and drain lines where flow is set by hand, and cast steel globe valves on DN50 and larger lines. On superheated steam lines above 425 °C, a WC6 or F22 body is needed instead of carbon steel. You can monitor the outlet temperature at the throttling point with temperature measuring equipment.
Advantages
Flow Setting
- Disc position changes the flow gradually.
- Used on lines needing manual throttling.
Short Stroke
- The disc travels a short way to close.
- Fast opening and closing.
Hard Seating
- Stellited seat and disc faces.
- Resistance to throttling erosion.
Two Constructions
- Cast and forged body options.
- One family from 1/2″ to 12″.
Certified Test
- API 598 pressure and tightness test.
- Every valve delivered tested.
Construction and Design Features
- Globe-pattern body in which the flow changes direction
- Disc attached to the stem by a disc nut
- Graphite packing and gland flange with eye bolts
- SS + graphite bonnet gasket, studded bonnet
- Back seat and stem bush with grease nozzle on cast types

How to Choose?
- Define the dutyClarify whether the valve will throttle or only shut off.
- Allow for pressure dropTake into account that a globe body causes higher loss than a gate valve.
- Select the pressure classSet the Class by the allowable pressure at design temperature.
- Choose the body materialPrefer a WC6 or F22 body above 425 °C.
- Install by flow directionConnect the valve following the arrow on the body.
