MNC Valves is a Manufacturers of Diaphragm Control Valve in India supplying industrial diaphragm operated control valves designed for reliable regulation of flow in corrosive, viscous, and sensitive process media.

Diaphragm control valves use a flexible diaphragm element to regulate flow while isolating the actuator mechanism from the process fluid.

These valves are widely used in industries where leak-free sealing and corrosion resistance are required.

Typical applications include:

• Chemical processing plants
• Water treatment plants
• Pharmaceutical industries
• Food processing plants
• Industrial fluid handling systems

PRODUCT DESIGN OVERVIEW

Diaphragm control valves regulate flow using a flexible diaphragm that moves against a seat to control the process fluid.

The diaphragm isolates the actuator components from the media, making the valve suitable for corrosive or contaminated fluids.

Typical assembly includes:

• Valve body
• Flexible diaphragm
• Compressor plate
• Valve bonnet
• Actuator assembly

This design ensures smooth throttling and reliable sealing performance.

VALVE CONFIGURATIONS

Two Way Diaphragm Control Valve

Two way diaphragm valves regulate flow between a single inlet and outlet.

Functions include:

• Flow control
• Pressure regulation
• Process isolation

These valves are commonly used in chemical and water treatment systems.

SIZE RANGE

• DN 15 mm to DN 200 mm (Standard)
• Larger sizes available on request

Pressure rating depends on design and material selection.

MATERIALS OF CONSTRUCTION

DESIGN FEATURES

• Leak-free diaphragm sealing
• Isolation of actuator components
• Smooth throttling control
• Low maintenance design
• Corrosion resistant configuration
• Suitable for sensitive process media

ACTUATOR FEATURES

Diaphragm control valves can be supplied with:

Features include:

• Pneumatic Actuator
• Electric Actuator
• Manual Operation

Pneumatic diaphragm actuation is commonly used in automated systems.

TESTING & QUALITY CONTROL

• The actuator moves the diaphragm toward or away from the valve seat.
• This movement regulates the flow of fluid through the valve.
• Because the diaphragm separates the actuator from the process fluid, contamination and corrosion risks are minimized.

INDUSTRIES SERVED

Diaphragm control valves are used in:

• Chemical processing plants
• Pharmaceutical manufacturing
• Water treatment systems
• Food and beverage processing
• Industrial fluid handling systems
