Kartar Valves is a significant player in the Indian valve manufacturing industry, and their butterfly valves are a key product in their extensive portfolio. They are known for providing reliable and cost-effective flow control solutions across various sectors. Here's a breakdown of Kartar butterfly valves: Key Characteristics and Features: Design & Types: Wafer Type: This is the most common type offered by Kartar. These valves are designed to be sandwiched between two pipe flanges and are held in place by through-bolts. Lug Type (less common, but may be available): While wafer type is prevalent, lug-type valves (with threaded holes for bolting to flanges) might also be part of their specialized offerings. Slimline Design: Kartar often emphasizes a sleek, slimline design for their butterfly valves, which helps minimize installation space and potentially reduce weight. Materials of Construction: Body: Commonly made from Cast Iron (CI), SG Iron (Ductile Iron), Cast Carbon Steel (CS), and Stainless Steel (SS). They also mention Aluminium Die-cast for some variants, ideal for PVC/PPR/HDPE pipelines. Disc: Typically made from SG Iron (Ductile Iron) or Stainless Steel (SS) (e.g., AISI 410, CF8/SS304, CF8M/SS316). Liner/Seat: Integrally molded or replaceable liners made from elastomers such as Nitrile (Buna-N), EPDM, Neoprene, or Silicon. These provide 100% leak-tight closure. Stem: Usually Stainless Steel (e.g., AISI 410, AISI 304). Bushing & O-rings: Teflon, Nylon, Viton for smooth operation and sealing. Operational Control: Lever Operated: For smaller sizes, offering manual on/off control with a handle that can lock the disc in various positions. Gear Operated: For larger valves, a gearbox is used to reduce the effort required for operation, providing smoother control. They are also self-locking. Actuated Valves: Kartar supplies butterfly valves that are direct actuator mountable (as per ISO 5211 standard flange), meaning they can be easily fitted with electric actuators or pneumatic actuators for automated on/off or modulating control in industrial processes or BMS (Building Management Systems). Performance & Standards: Pressure Ratings: Available in PN10 and PN16 (1.0 MPa and 1.6 MPa respectively), with some Cast Steel versions offering PN20. Temperature Range: Generally from -10°C to 65°C for standard models, with some materials supporting wider ranges. Leakage: Designed for 100% leak-tight closing and bi-directional sealing. Certifications: Many Kartar butterfly valves are ISI Marked (IS:13095) and conform to international standards like BS 5155 and API-609, MSS SP-67, and ISO 5752 face-to-face dimensions. Durability: Made with robust materials to resist corrosion, abrasion, and wear, ensuring long operational life. Applications: Kartar butterfly valves are widely utilized across various sectors in India and internationally: Water Management: Water treatment plants, water distribution networks, pumping stations, irrigation, and raw water conveyance. Fire Fighting Systems: Crucial for flow control in fire hydrant lines and sprinkler systems. Models with supervisory switches are often used for this. HVAC Systems: Used in heating and air conditioning systems for controlling chilled water and hot water flow. Industrial Processes: Chemical industry, sugar industry, paper & pulp industry, power generation (thermal plants, hydel projects), waste & effluent treatment plants, compressed air lines, and general industrial pipelines. Agriculture: For water control in farming applications. Typical Models & Pricing (Approximate in India - as of July 2025): Kartar offers various models, often differentiated by material and operating mechanism (e.g., K701N, K704, K713). Price Range: The price for a Kartar butterfly valve varies significantly based on size, material, and automation (manual vs. actuated). Lever Operated Cast Iron Wafer Type (e.g., 50mm to 100mm / 2-4 inches): You can expect prices roughly from ₹900 to ₹4,000 per piece (excluding GST). Lever Operated Cast Iron Wafer Type for larger sizes (150mm to 300mm / 6-12 inches): Prices could range from ₹5,000 to ₹20,000+ per piece. Gear Operated Cast Iron Wafer Type: These will typically be a few thousand rupees more than their lever-operated counterparts for the same size. Actuated Butterfly Valves (Electric or Pneumatic): These will be significantly more expensive, starting from around ₹10,000 for smaller sizes and going much higher for larger, automated units.

Jindal MS pipe“ refers to Mild Steel (MS) pipes manufactured by one of the various companies operating under the Jindal brand in India. The Jindal Group is a large conglomerate with diverse interests, and several of its entities are involved in steel and pipe manufacturing. The most prominent ones that come to mind when talking about MS pipes are often: Jindal Pipes Limited (JPL) / Jindal Star: This is a major manufacturer of ERW (Electric Resistance Welded) steel pipes, including black and galvanized MS pipes, up to 14” NB (Nominal Bore) as per IS:1239 and larger sizes (8“ and above) as per IS:3589. They are very well-known in the plumbing, water, gas, and structural applications market. Jindal SAW Ltd.: While they also produce large diameter SAW (Submerged Arc Welded) pipes primarily for oil and gas, and water transportation, which can be MS, their focus is generally on larger diameter line pipes. Jindal Supreme (India) Private Limited: This company manufactures and wholesales GI, Rectangular, and MS pipes. What are MS Pipes? MS pipes, or Mild Steel pipes, are made from low-carbon steel (typically 0.05% to 0.25% carbon content). This low carbon content makes them: Ductile: They can easily change shape without losing their toughness. Weldable: Easy to fabricate and join. Strong and Durable: They possess good tensile strength and can withstand significant loads, pressures, and temperatures. Cost-Effective: Relatively inexpensive compared to other types of pipes like stainless steel. Corrosion Resistant (when treated): While not entirely immune to rust, they can be treated with protective coatings (like galvanization or paint) to enhance their resistance to corrosion and abrasion. Jindal MS Pipe Specifications and Standards: Jindal MS pipes are manufactured to comply with a wide range of national and international standards, ensuring their quality and suitability for various applications. Common standards include: Indian Standards (IS): IS 1239 (Part-I): For mild steel tubes, tubulars, and other welded steel fittings (common for sizes up to 6” NB). IS 3589: For MS pipes used in water, gas, and sewage transmission (common for sizes 8“ and above). Grades like Fe330 and Fe410 are typical. IS 1161: For structural pipes (Grades YST 210, YST 240, and YST 310). IS 3601: Steel Tubes for Mechanical & General Engineering. IS 4270: Steel Tubes for Water Wells (Casing Pipes). International Standards: ASTM (American Society for Testing and Materials): ASTM A53 (for water, gas, air), ASTM A795 (fire protection), ASTM A135 (conveying liquids/gases), ASTM A500 (structural). API (American Petroleum Institute): API 5L (for oil & gas conveying at high pressure). BS (British Standards): BS 1387, BS 1775, BS 1139, BS 534, BS 6363. DIN (German Standards): DIN 2440, 2441. ISO 65. Common Sizes and Dimensions: Jindal MS pipes are available in a vast range of sizes: Outer Diameter: Typically from 1/2” (15mm NB) up to 20“ NB or even larger (e.g., 60” for SAW pipes from Jindal SAW). Wall Thickness: Varies from 2.00mm to 10.00mm or more, depending on the nominal bore and class (Light, Medium, Heavy) as per IS standards, or schedule numbers (e.g., SCH 40, SCH 80) as per ASTM standards. Length: Standard lengths are often 6 meters (20 feet), but customizable lengths may be available. Manufacturing Process: Jindal primarily uses the Electric Resistance Welded (ERW) and High Frequency Induction Welded (HFIW) processes for their smaller to medium diameter MS pipes. For larger diameters (e.g., above 16-20 inches), Submerged Arc Welded (SAW) processes (UOE, JCOE, Helical) are used, primarily by Jindal SAW.
