Double disc gate valve manufacturers in India
Speciality Valve is a pre-eminent Double disc gate valve manufacturers in India, producing top-quality, dependable, and precision-engineered valves for precise flow control applications. Our valves are engineered to provide bubble-tight shutoff, lower leakage, and silky-smooth operation for a wide variety of industries.
Why Required?
Double disc gate valves are essential where zero leakage and constant sealing are important. They are employed in piping systems that carry water, steam, oil, gas, and other fluids to provide improved performance under high-pressure and high-temperature applications.
Key Components of Double Disc Gate Valve:
Body: Typically fabricated from cast iron, ductile iron, or stainless steel
Discs (2): Two discs which bear on the seats on both sides to prevent flow
Stem: Mechanically executes the movement of the discs
Wedge or Spreader: Assists to separate and seat the discs closely
Bonnet: Enclosed cover that safeguards internal parts
Working of Double Disc Gate Valve:
Double disc gate valve operates based on a stem that lowers and raises two discs at a time. These discs are pushed outward against the valve seats by a wedge or spreader mechanism, providing a close seal on both ends. Upon opening, the wedge draws the discs toward each other, minimizing wear and facilitating smooth running.
Advantages of Double Disc Gate Valve:
Offers bidirectional, bubble-tight shutoff
Suitable for high-temperature and high-pressure services
Reduced torque requirement for opening
Less wear on seat, resulting in increased service life
Simple maintenance and inspection
