Available in materials like gun metal and cast iron. Butterfly Valves: Soft Seat Butterfly Valves: Featuring centric disc construction, single-piece bodies, and integrally molded seats for excellent sealing. Available in wafer type and lug type configurations. Disc materials often include S.G. Iron (Ductile Iron) or Stainless Steel (SS). Offered with lever operated (for manual control) and gear operated (for smoother operation of heavy-duty valves). Motorized Butterfly Valves: Equipped with electric quarter-turn actuators, suitable for automated ON/OFF operations and compatible with Building Management Systems (BMS). Ball Valves: Forged Brass Ball Valves: Available in various sizes, often with full bore and PN-25 pressure ratings. Ball Valves with Strainers: A popular choice for HVAC and plumbing, these valves integrate a strainer to remove particulates from fluids, protecting downstream equipment like pumps and regulators. Extended Stem Ball Valves: For specific installation requirements. Check Valves: Dual Plate Check Valves: Lightweight, compact, wafer-type check valves designed for HVAC and general service. They use two spring-loaded plates for quick closure and minimal head loss. Single Plate Wafer Check Valves: Another option for preventing backflow. Available in materials like cast iron (CI) and stainless steel (SS). Forged Brass Vertical Lift Check Valve and Forged Brass Swing Check Valve. Pressure Reducing Valves (PRV): Designed to maintain a stable downstream pressure, essential for protecting equipment and optimizing system performance. Test and Drain Valves: Compact, three-position ball valves (OFF, TEST, DRAIN) specifically designed for testing and draining wet pipe fire sprinkler systems, offering ease of maintenance and compliance.

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.
