COREX V30.1 Angle Globe Valve

The COREX V30.1 is a flanged angle globe valve with graphite packing, designed for flow isolation in water, hot water, steam, air, oils, and non-corrosive fluids without coarse mechanical impurities. The angle configuration is used when piping changes direction by 90° and requires simultaneous isolation.

Versions and Operating Limits

• Spheroidal Cast Iron GGG40.3: DN15–DN300, PN10 / PN16, operating temperature -10 to 250°C.
• Cast Steel 1.0619 / GS-C25: DN15–DN300, PN16 / PN40, up to 425°C per manufacturer datasheet. Product page states -27°C as minimum temperature, while COREX brochure states -19°C; value should be confirmed in technical offer.
• Connection: flanged, with handwheel.
• Packing: graphite.
• Seat / disc: stainless sealing surfaces X5CrNi189 or X20Cr13, depending on version.

Standards

The cast iron version refers to design EN 13709 / EN 12516, flanges EN 1092-1, and pressure testing EN 12266-1. The steel version also mentions EN flanges and EN 12266 tests.

Applications

Used in:

• low or medium pressure steam lines,
• hot water networks and auxiliary boiler circuits,
• industrial air,
• non-corrosive fluids and oils,
• piping points where direction change and isolation with a single valve are required.

Selection and Maintenance

Selection is based on DN, PN, temperature, body material, fluid compatibility, and allowable pressure drop. For temperatures above 250°C or PN40, the steel version is required.

Maintenance checks focus on graphite packing, seat tightness, and fluid cleanliness. Particles on the seat can cause scoring and closure leakage.

FAQ

Is it a control valve?

Primarily an isolation globe valve. Limited throttling should be evaluated for noise, velocity, seat wear, and differential pressure.

When to choose an angle version?

When piping layout requires a 90° turn and installation can be simplified without additional elbows or fittings.
