INTRODUCTION

A membrane valve is a highly reliable flow control valve widely used in industries where hygiene, corrosion resistance, leak-tight shutoff, and low maintenance are critical requirements. At Krishna Industries, Ahmedabad, we manufacture and supply premium-quality membrane valves engineered for long service life, consistent performance, and compatibility with Indian industrial operating conditions.

Membrane valves are also commonly referred to as diaphragm valves and are closely associated with industrial diaphragm valves, PTFE lined diaphragm valves, rubber lined diaphragm valves, and sanitary diaphragm valves. These valves operate using a flexible membrane that controls the flow by moving up and down against a weir or straight-through body. This simple yet robust mechanism ensures bubble-tight shutoff and excellent isolation from the process media.

Krishna Industries has positioned itself as a dependable membrane valve supplier in Ahmedabad, Gujarat, India by focusing on precision manufacturing, strict quality control, and application-oriented design. Our membrane valves are supplied across India to chemical plants, pharmaceutical companies, water treatment facilities, power plants, textile units, food processing industries, and OEM system integrators.

Unlike conventional gate valves or globe valves, membrane valves do not have sliding or rotating metal-to-metal contact with the process fluid. This makes them ideal for corrosive fluids, abrasive slurries, viscous media, and ultra-clean applications. With increasing demand for safe and maintenance-friendly valves in Indian industries, membrane valves have become a preferred choice.

Krishna Industries membrane valves are designed to meet Indian industrial standards and site conditions, offering consistent performance even under fluctuating pressure, temperature, and flow conditions.

WHAT IS A MEMBRANE VALVE

A membrane valve is a type of linear motion valve that uses a flexible membrane to regulate, start, stop, or throttle the flow of fluid. The membrane is usually made from rubber, EPDM, PTFE, neoprene, or other elastomers depending on the application.

The membrane is compressed against a valve body seat or weir when closed, forming a tight seal. When opened, the membrane lifts, allowing fluid to pass through the valve. Because the membrane isolates the operating mechanism from the process fluid, internal components remain protected from corrosion and contamination.

This construction makes membrane valves extremely suitable for aggressive chemicals, slurries, and hygienic fluids.

TYPES OF MEMBRANE VALVES SUPPLIED BY KRISHNA INDUSTRIES

Krishna Industries supplies a comprehensive range of membrane valves suitable for Indian industrial applications.

Weir Type Membrane Valve
This is the most commonly used membrane valve design. The raised weir provides better shutoff, longer membrane life, and efficient throttling.

Straight Through Membrane Valve
Designed for high-viscosity fluids and slurries where minimum flow restriction is required.

Rubber Lined Membrane Valve
Ideal for abrasive and corrosive services in chemical and mining industries.

PTFE Lined Membrane Valve
Used in highly corrosive chemical processes requiring superior chemical resistance.

Sanitary Membrane Valve
Specifically designed for pharmaceutical, food, beverage, and biotech applications.

Manual Operated Membrane Valve
Simple handwheel operation for standard flow control.

Pneumatically Operated Membrane Valve
Used in automation systems requiring remote or frequent operation.

DESIGN ADVANTAGES

Membrane valves offer several operational advantages over traditional valve designs.

Leak Proof Operation
The flexible membrane ensures bubble-tight shutoff even after repeated operation.

Corrosion Resistance
Process media does not come in contact with moving metal parts.

Low Maintenance
Minimal internal components reduce wear and maintenance frequency.

Hygienic Design
Smooth internal surfaces prevent fluid accumulation and contamination.

Bidirectional Flow
Most membrane valves allow flow in both directions.
