Speciality Valve is an established Diaphragm Valve Manufacturers in India that provides high-performance Diaphragm Valves that guarantee safe and precise flow control. The diaphragm valves are used for clean, leak-free, and efficient control of fluids in corrosive or viscous fluid systems. These valves are hygienic and reliable in nature and are the most desired valve type in the pharmaceutical, water treatment, and chemical process industries.
Meaning of Diaphragm Valve:
A diaphragm valve uses a flexible diaphragm to seal the fluid flow. On operation, the diaphragm is forced downward over a weir or seat in the body of the valve, thus closing the flow. This arrangement makes the valve highly suitable to applications requiring cleanliness as well as leak-tight operation.
Why Required?
These valves are required in applications wherein contamination should not occur, or in applications wherein aggressive media would be detrimental to conventional valve materials. This valve is useful for applications wherein cleanliness, compactness, and ease of maintenance will have significant importance in achieving a higher standard level of hygiene, resistance to chemicals, and control.
Key Components of Diaphragm Valve:
- Valve Body: Generally made of stainless steel, cast iron, and plastic
- Diaphragm: Made of rubber, PTFE, or elastomer as needed in the media.
- Actuator or Handwheel: Which raises or lowers the diaphragm.
- Bonnet: This holds the actuator parts.
- Weir or Seat: The part of the body covered by the diaphragm.
Working of Diaphragm Valve:
Actuation or turning of the actuator or handwheel drives the diaphragm down to the seat, sealing the flow of fluid. When the diaphragm is opened, it goes up to allow flow. This has the advantage of fewer leak points and potential contamination areas since there is no universal stem-packing design.
Applications of Diaphragm Valves
- Pharmaceutical Manufacturing – Ideal for cleanroom processing and handling sterile fluids.
- Food & Beverage – Perfect for dairy systems, sugar refining, and brewery pipelines.
- Chemical Plants – Designed to manage corrosive fluids and toxic chemicals safely.
- Water Treatment Plants – Essential for chlorine and fluoride dosing, as well as effluent control.
- Mining and Slurry Handling – Well-suited for abrasive and viscous fluids.
Advantages of Diaphragm Valve:
- Suits corrosive and viscous liquids best
- Clean and leak-free operation
- Easy maintenance and replacement
- On/off and throttling control
- Small with low dead space
Diaphragm Valve vs Ball Valve – What’s the Difference?
- Design: Diaphragm valves utilize a flexible membrane to regulate flow, whereas ball valves operate with a rotating ball.
- Sealing: Diaphragm valves provide a bubble-tight shutoff without any fluid contact on moving parts, while ball valves can leak if their seats wear out.
- Applications: Diaphragm valves are favored in sterile and corrosive settings, while ball valves are typically used in high-pressure pipelines.
- Maintenance: With fewer moving parts exposed to fluid, diaphragm valves present a lower risk of contamination and are easier to clean.
- Throttling: Diaphragm valves excel at modulating flow, while ball valves are primarily used for on/off operations.
