A Double Disc Gate Valve Manufacturers in India is also known as a double gate valve, wherein two parallel discs move vertically with their movement to regulate the fluid. In this valve, tight sealing and efficient flow are attained in the regulation of various fluids inside piping systems.

Working

1. Operation: The valve is operated using a handwheel or actuator. The handwheel is turned, hence the attached stem and the discs move vertically.
2. Opening: When the stem is raised, the discs open simultaneously to allow a large opening to the fluid; hence, the pressure drop and turbulence are significantly minimized.
3. Closing: On closing, the discs fall down and contact with the valve body, thereby sealing off snugly without leakage.
4. Flow Direction: The double disc design features bi-directional flow option that can be used in various uses.

Advantages

● Versatility: Works well with a variety of fluids such as liquids and gases.
● The low pressure drop improves pumping efficiency, making Double Disc Gate Valve Manufacturers in India a preferred choice in industrial setups.
● The valves are made of strong materials and their parts are available for repairs.
● The valves are easy to install, repair, and clean.

Industries Using

● Water and Wastewater Treatment:
● Oil and Gas
● Power Generation
● Chemical Processing
● Mining and Mineral Processing

Components of Double Disc Gate Valve Manufacturers in India

1. Body-Made from materials of great strength like cast iron, carbon steel, or stainless steel so that the body is a solid compact body.
2. Discs- There are two discs working parallel to either open or close the valve.
3. Stem- Serves to connect both the disc to the handwheel or actuator for movement.
4. Bonnet- This is part used to encase the stem plus cover seals; this is mostly for the purpose of protecting its interior mechanism.
5. Seating Surfaces-The surfaces on which the discs close against the body to ensure a proper seal.
6. Actuator/Handwheel- A mechanism used to operate the valve either directly by hand or by some automatic device
