The globe valve range from JC valves has high precision fabrication that considers the making of the following components with utmost care

Stem

  • Single piece forging
  • ACME threading
  • Smooth finishing in order to minimize friction.

 Body and Bonnet Gasket

  • Circular male-female connection for Class 150 to 600 globe valves with a graphite or spiral wound gasket.
  • Ring type joint for Class 900 and above

 Body and Bonnet

  • High quality cast
  • Precisely machined,
  • Customized to prevent stress concentration.
  • Bonnets perfectly aligned to body – either of one piece only – or two pieces, depending on the size of the valve.
  • Ensure accurate opening and closing.
  • Bodies of globe valves are designed with the same characteristics as gate valves, which ensures that the disc is guided in bigger valve sizes or high pressure service in order to avoid vibrations and better seat.

 Backseat

  • For gate and globe valves, the backseat is threaded in the bonnet
  • For pressure seal valves, the backseat is welded to the bonnet.
  • The hard facing is stellite 6 or equivalent.

Bolted Bonnet

All globe valves utilize the “port closure” concept of valves. By this it meant that fluid passes through a specific opening (rather than a general passageway, as in the case of gate valves), and the fluid is controlled by means of a stem-mounted disc or inserted plug in that area.

Despite of lacking the straight through, unobstructed passageway of the gate valve, these globe types are superior in two key aspects – throttling and serviceability under frequent use. They are better at the throttling function because they permit fluid to exit uniformly around the circumference of a seat, rather than “slicing” down to limit passage through a narrowly restricted area.
