Class 900 (PN150)	1" - 16"	12mm - 75mm	Full bore, Reduced bore
Class 1500 (PN250)	1" - 12"	15mm - 85mm	Full bore only
Class 2500 (PN420)	1" - 8"	18mm - 95mm	Full bore only

Material-Specific Dimensional Considerations

Different materials require adjusted dimensions for optimal performance and safety. Here's what we customize based on material selection:

Stainless Steel (304, 316, 316L, 321)

• Standard dimensions with enhanced corrosion resistance
• Wall thickness increased by 10-15% for aggressive media
• Special bore configurations for sanitary applications

Carbon Steel (WCB, LCC, LCB)

• Industry-standard dimensions for petroleum applications
• Cryogenic extensions for low-temperature service (-196°C to +425°C)
• Extended bonnets for high-temperature steam systems

Alloy Materials (Inconel, Hastelloy, Monel)

• Customized dimensions for corrosive chemical processing
• Thicker body walls to accommodate aggressive media
• Special seal groove designs for metal-to-metal seating

Duplex and Super Duplex Stainless Steel (2205, 2507)

• Optimized dimensions for offshore and marine environments
• Enhanced body strength for seawater applications
• Special trim configurations for chlorides resistance

Bore Type Dimensional Configurations

We offer three primary bore types, each with specific dimensional characteristics:

Full Bore (Full Opening)

• Bore diameter equals pipe inner diameter
• Minimal pressure drop across valve
• Ideal for: slurry, pigging operations, high-flow requirements
• TypicalCv values: 1.2 times pipe diameter squared

Reduced Bore (Standard Bore)

• Bore diameter typically one size smaller than pipe
• Standard dimensions reduce manufacturing costs
• Ideal for: general service, on/off applications
• Cv values: approximately 70-80% of full bore equivalents

Vented Bore (Venturi)

• Special contour design maintains near-full flow
• Unique dimensional profile for erosion resistance
• Ideal for: abrasive media, mineral processing
• Cv values: 90-95% of full bore performance
