Pressure seal globe valves

Features and benefits

Velan globe valve’s top and bottom-guided disc assures stem operation without side thrust caused by high pressure flow. The non-rotating stem results in lower friction of all moving parts and longer stem packing life. All this resulting in smooth, easy operation and tight shutoff under extreme pressures.

• Velan's proven pressure seal design to ASME B16.34.
• Live-loaded pressure seal bonnet bolting on NPS 6 and larger as a standard.
• Body – superior strength forgings / high quality castings.    
• Body guided disc eliminates side thrust and provides longer disc, seat and body life.
• Impactor handwheel for tight shutoff.
• Velan stem seal offers tight seal with little to no maintenance over long periods of time.
• Non-rotating stem requires lower operating torque.
• The body and disc are CoCr alloy hardfaced on seat contact and disc guiding surfaces, which provides maximum resistance to erosion and wear.
• Optional live-loading of packing extends low emission service life especially in service with large pressure/temperature transients or frequent cycling.
• Other sizes and pressure classes available. Contact the company for specifications.
