Marine valve solutions for demanding environments

In production, refining and processing, a valve may need to keep sealing when the line around it is on fire. That's why fire-safe testing matters. Selected MARS series are fire-tested to API 607.

Typical duties

• Isolation on hydrocarbon process lines
• Emergency shutdown with actuated packages
• Sour service, with NACE MR0175 available as an option on selected fire-safe series

Recommended MARS valves

• Fire-safe ball valves: Series 28, 83, 88, 90, 90D and 91D
• Flanged ball valves
• Metal seated ball valves (ANSI Class 600 three-piece) for abrasive or high-temperature duty
• Actuated packages

Hygienic lines need valves that clean easily, trap as little product as possible, and use the right grade of stainless steel. MARS sanitary ball valves have tri-clamp or tube OD butt weld ends, a full port and PTFE seats, with cavity filler seats available on selected series.

Typical duties

• Product isolation in dairy, brewing and beverage lines
• Clean-in-place (CIP) circuits
• Pharmaceutical and cosmetics process lines
• Diverting between tanks with multi-port sanitary valves

Recommended MARS valves

• High-performance sanitary ball valves: Series 77SN, 88SN and 83SN, with a CF3M body and 316L stem
• Sanitary multi-port valves: Series 33SN, 3-way L-port or T-port
• Economical sanitary ball valves: Series 55SN and 50SN
• Sanitary butterfly valves

Municipal and industrial water systems need valves that resist corrosion over long service lives with little maintenance.

Typical duties

• Isolation on treatment and distribution lines
• Chemical dosing (chlorine and pH correction)

Recommended MARS valves

• Two-piece ball valves for general isolation
• Flanged ball valves

From compressed air and hydraulic circuits to process skids and OEM builds, equipment builders need valves that stay consistent from batch to batch, so they can design around a known specification.

Typical duties

• Compressed air and utility isolation
• Process skids and packaged plant
• OEM equipment builds

Recommended MARS valves

• One-piece ball valves
• Two-piece ball valves (NPT, BSP, BSPT)
• Three-piece ball valves
• Direct mount series for automated skids
