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:

1) Body: Typically fabricated from cast iron, ductile iron, or stainless steel
2) Discs (2): Two discs which bear on the seats on both sides to prevent flow
3) Stem: Mechanically executes the movement of the discs
4) Wedge or Spreader: Assists to separate and seat the discs closely
5) 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:

1) Offers bidirectional, bubble-tight shutoff
2) Suitable for high-temperature and high-pressure services
3) Reduced torque requirement for opening
4) Less wear on seat, resulting in increased service life
5) Simple maintenance and inspection

Functions of Double Disc Gate Valve:

1) Absolute isolation of flow
2) Effective shutoff in any direction of flow
3) Applicable for corrosive, abrasive, or high-pressure fluids

Types of Double Disc Gate Valve:

1) Double disc gate valve with rising stem
2) Double disc gate valve with non-rising stem

Industries:

1) Power generation
2) Oil and gas
3) Petrochemical
4) Water treatment facilities
5) Marine and offshore platforms
6) Pulp and paper industry
