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.
- Body guided disc eliminates side thrust and provides longer disc, seat and body life.
- Impactor handwheel for tight shutoff.
- Designed to ASME B16.34.
- Body made of superior strength forgings and optional cast steel.
- Velan stem seal offers tight seal with little to no maintenance over long periods of time.
- Optional live-loading of packing.

Features and benefits
Velan pressure seal y-pattern globe valves offer lower and higher Cvs.
Velan's proven pressure seal design.
- Low pressure drop compared to vertical globe valves.
- Excellent resistance to the effects of thermal cycling.
- Low torque stroking due to: 1) radial thrust bearings; 2) non-rotating stem; 3) impactor handwheel (3 –10 times more effective than standard handwheel).
- Quick and easy repair in line.
- Seat integrally hardfaced with CoCr alloy.
- Disc fully guided with CoCr alloy seating and guiding surfaces.
- Tight shutoff.
- Stem expansion/contraction thrust unit for high temperature application (optional).
- Other sizes available on request.
- Live-loading of packing optional

Features and benefits
Velan's proven pressure seal design.
- No penetration of hinge pin to outside eliminating possibility of pin seal leakage and allowing for in-line service.
- Compact cage unit: all moving parts are attached to the carrier and can be removed easily for service.
- Forged seat/disc is CoCr alloy, ground and lapped to a mirror finish for maximum erosion resistance and long service life. It is seal-welded to the body.
- Disc can partially rotate for tight shutoff. In the fully open position, it rests against a stop.
- CoCr alloy bearings for hinge pin.
- Easy in-line service. All parts are easily accessible for maintenance. Seating faces can be re-lapped.
- Forged bonnet.

Features and benefits
- Velan's proven pressure seal design.
- Unique cage unit: entire seat-hinge-pin-disc assembly can be tested outside the valve before seal welding into the body. Eliminates pin seal leakage.
- Easy in-line service.
- Efficient operation. The hinge pin located near the center of gravity allows the conical seating face of the disc to move out and into the seat rapidly without sliding or wear. The disc pivots through a small arc preventing backflow and “water hammer”.
- Superior tightness: conical, lapped-in hardfaced seating is self-aligning. Valve can be used even in vertical piping with flow up.
