Diaphragm valves are one of the most reliable and contamination-free flow control devices used across Indian process industries. Designed for precise regulation, on-off control, and throttling of fluids, diaphragm valves are widely preferred in applications where hygiene, corrosion resistance, and leak-proof operation are critical. Krishna Industries, based in Ahmedabad, Gujarat, India, is a trusted supplier of industrial diaphragm valves engineered to meet Indian operating conditions and international quality expectations.
A diaphragm valve operates using a flexible elastomer or PTFE diaphragm that moves up and down to control the flow of fluid. Unlike gate valves, globe valves, or ball valves, diaphragm valves isolate the working mechanism from the process fluid. This design eliminates leakage through the stem and minimizes contamination, making diaphragm valves ideal for chemical processing, water treatment, pharmaceuticals, food processing, fertilizers, and effluent handling systems.
Krishna Industries supplies a comprehensive range of diaphragm valves including rubber lined diaphragm valves, PTFE lined diaphragm valves, manual diaphragm valves, pneumatically operated diaphragm valves, and diaphragm control valves. These products are often searched and specified alongside industrial valve keywords such as chemical diaphragm valve, weir type diaphragm valve, straight-through diaphragm valve, corrosion resistant diaphragm valve, and industrial diaphragm control valve. Our diaphragm valves are engineered for long service life, low maintenance, and consistent performance under demanding Indian industrial environments.
Positioned strategically in Ahmedabad, Gujarat, Krishna Industries serves customers across India with dependable supply, competitive pricing, and technical support. We understand Indian buyer requirements such as rugged construction, ease of maintenance, local availability, and cost efficiency. With a minimum order quantity of 10 units, our diaphragm valves are suitable for project requirements, plant maintenance, and OEM applications.
A diaphragm valve is a linear motion valve that uses a flexible diaphragm to regulate flow. The diaphragm is connected to a compressor or stem that presses the diaphragm against a weir or valve body seat to stop flow. When the stem is lifted, the diaphragm moves upward, allowing fluid to pass.
Key distinguishing features of diaphragm valves include: • Zero stem leakage • Excellent sealing capability • Suitable for corrosive and slurry media • Easy cleaning and maintenance • Minimal dead space
These characteristics make diaphragm valves superior to many conventional valves in specific industrial applications.
TYPES OF DIAPHRAGM VALVES SUPPLIED BY KRISHNA INDUSTRIES
1. Weir Type Diaphragm Valve Weir type diaphragm valves feature a raised lip or weir inside the valve body. They are widely used for clean, corrosive, and high-purity fluids. These valves offer excellent shut-off and longer diaphragm life due to reduced flexing.
2. Straight Through Diaphragm Valve Straight-through diaphragm valves have a full bore design with no internal obstruction. They are ideal for slurries, viscous fluids, and applications where solids are present.
3. Rubber Lined Diaphragm Valve Rubber lined diaphragm valves are used for abrasive and corrosive services such as acids, alkalis, and wastewater. Common lining materials include EPDM, Neoprene, and Natural Rubber.
4. PTFE Lined Diaphragm Valve PTFE lined diaphragm valves are suitable for aggressive chemicals and high-purity applications. They offer excellent chemical resistance and long service life.
5. Manual Diaphragm Valve Operated using a handwheel, manual diaphragm valves are simple, reliable, and economical. Ideal for isolation and throttling applications.
6. Pneumatically Operated Diaphragm Valve These valves are actuated using compressed air and are commonly used in automated process plants requiring remote or frequent operation.
The working principle of a diaphragm valve is straightforward yet highly effective. Rotation of the handwheel or actuator moves the compressor vertically. This motion pushes the diaphragm downward onto the valve seat or weir, stopping the flow. When the compressor is lifted, the diaphragm flexes upward, creating a flow path.
Since the diaphragm separates the fluid from the moving parts, there is no contact between the process media and the stem or actuator. This results in: • No external leakage • Reduced wear and corrosion • Longer operational life
