MIT Valves
MIT BUTTERFLY VALVES CI DISC
The MIT Cast Iron (CI) Butterfly Valve with SG Iron Disc is a robust, reliable, and cost-effective solution designed for efficient flow regulation and shut-off applications in water, HVAC, fire-fighting, and industrial piping systems. Manufactured with a heavy-duty cast iron body and a spheroidal graphite (SG) iron disc, this valve ensures excellent strength, durability, and corrosion resistance. The wafer-type design allows for compact installation between flanges, making it ideal for space-constrained systems. With its smooth quarter-turn operation and precision-sealed construction, the MIT CI Butterfly Valve delivers long service life and low maintenance performance across a wide range of operating conditions.

MIT Wafer Type Check Valve – Swing Type / Non-Return Valve
The MIT Wafer Type Check Valve is a compact, lightweight, and high-performance non-return valve designed to prevent backflow in pipeline systems. Its streamlined wafer design allows easy installation between flanges, significantly reducing weight and space requirements compared to conventional swing check valves. The valve operates automatically — the disc opens with forward flow and closes instantly when flow reverses, ensuring system integrity and preventing damage to pumps, compressors, and other downstream equipment.
Engineered with precision machining and robust materials, the MIT wafer check valve ensures reliable performance, low cracking pressure, and tight shut-off across a wide range of fluid applications including water, oil, gas, and chemical media. Its minimal maintenance design and durable construction make it an ideal choice for industrial, HVAC, water treatment, and fire-fighting systems.
- Automatic Operation: Opens with forward flow and closes immediately upon flow reversal to prevent backflow.
- Compact Wafer Design: Lightweight and space-saving, easy to install between standard flanges.
- High Durability: Constructed from premium-grade cast iron, carbon steel, or stainless steel for long service life.
- Leak-Proof Performance: Precision-machined disc and seat ensure tight shut-off and reliable sealing.
- Low Cracking Pressure: Reduces pressure loss and enhances system efficiency.
- Maintenance-Free: Simple design with minimal moving parts for low maintenance requirements.
Technical Specifications:
- Size Range: 40 mm to 600 mm
- Body Material: Cast Iron / Ductile Iron / Carbon Steel / Stainless Steel
- Disc Material: Stainless Steel / SG Iron
- Seat: Metal-to-Metal or Soft-Seated (NBR / EPDM / Viton)
- Pressure Rating: PN10 / PN16 / ANSI 150#
- End Connection: Wafer Type (fits between standard flanges)
Applications:
Water Supply, Fire-Fighting, HVAC, Industrial Process, Oil & Gas, Chemical Pipelines.
