Marck is a notable manufacturer of industrial valves in India, and they offer a range of Mild Steel (MS) ball valves. Here's a breakdown of information regarding Marck MS ball valves: About Marck Valves: Marck is represented by several entities, including 'Marck & Care Engineers Limited' and 'Marck Engineers, ' operating from different locations like New Delhi and Surat. They have a history in the valve manufacturing industry, providing a wide array of industrial valves. Marck MS Ball Valve Specifications (General): While specific models may vary, common specifications for Marck MS ball valves often include: Material: Mild Steel (MS) or Carbon Steel (CS) - which is essentially a type of mild steel used for valve bodies. Design: Available in various designs, including: One-piece, Two-piece, and Three-piece designs: Three-piece designs are often preferred for their ease of maintenance (the center section can be removed without disturbing the pipe connections). Flanged End: Common for industrial applications where secure, leak-proof connections are required. Screwed End/Threaded: For smaller sizes and lower pressure applications. Valve Size: Ranges widely, from small sizes like 15mm (1/2 inch) up to larger industrial sizes (e.g., 2 inch, or even up to 56 inches for some models). Maximum Pressure: Often rated for pressures like 16 bar (for certain MS ball valves) up to higher classes like 150#, 300#, 600# (referring to ASME pressure classes). Some heavy-duty valves can handle up to 700 bar. Maximum Temperature: Can vary, but typically around 100°C to 220°C for standard MS ball valves, though specialized versions might handle higher. Media: Suitable for various media including: Water Oil Gas (LPG, natural gas) Air Operation: Manual (lever or gear operated) or Actuated (electric or pneumatic actuators for automated control). Stem Type: Often comes with an SS (Stainless Steel) stem for better corrosion resistance. Applications of MS Ball Valves: Mild Steel (or Carbon Steel) ball valves are widely used in industrial and commercial applications where: On/Off Control: They provide quick, reliable, and bubble-tight shut-off for fluids and gases. High Pressure/Temperature: MS/CS valves are robust and can handle higher pressures and temperatures compared to some other materials like PVC. Durability: They offer excellent durability and a long service life. Various Industries: Common in: Oil and Gas (onshore and offshore facilities, fuel gas systems) Water and Wastewater Treatment Chemical Processing (depending on chemical compatibility) HVAC systems Manufacturing Power Generation Fire-fighting systems
