Control Valve Diaphragms - India

A control valve diaphragm is a flexible membrane, typically made of rubber or reinforced elastomer, used in diaphragm actuators to regulate fluid flow. When compressed air is applied, the diaphragm flexes, moving the valve stem to open or close the valve. This mechanism allows for accurate positioning of the valve, enabling precise control over flo...

Air-Operated Double Diaphragm - India

AODD diaphragms are central components in Air-Operated Double Diaphragm (AODD) pumps, which are positive displacement pumps commonly used in chemical processing, mining, food & beverage, and wastewater industries. In an AODD pump, compressed air alternately pushes each diaphragm, creating suction and discharge strokes that draw i...

S Series Saunders Weir A Type Diaphragms - India

Saunders’ S Series Weir A Type diaphragms are used in weir-type diaphragm valves, which are ideal for controlling or isolating flow in clean or aggressive process environments. The "Weir A Type" refers to the diaphragm profile that seats against the weir (raised saddle) inside the valve body, ensuring tight ...

Straight Through KB Type Diaphragms - India

KB Type diaphragms must flex further to make contact with the valve seat, so they are constructed with high-flexibility elastomers and often reinforced with fabric or composite layers for durability. These diaphragms typically include a molded body and a backing plate (metal or plastic) for precise alignment ...

Rubber Gaskets - India

Rubber gaskets are mechanical seals placed between two surfaces (such as flanges) to create a tight, leak-proof sealwhen compressed. Made from various elastomers, these gaskets accommodate surface irregularities, vibration, and pressure changes in systems transporting liquids or gases. By ensuring the integrity of fluid and gas syste...

Die-Cut Gaskets - India

Die-cut gaskets are created by stamping gasket material into a specific shape using a steel rule die or custom cutting tool. This process is ideal for producing flat gaskets in large quantities with tight tolerances and uniform thickness. Die-cut gaskets can be made from a variety of materials, including ...

Flange Gaskets - India

Flange gaskets are used to seal the space between two mating flanges, ensuring leak-proof connections under pressure. When compressed between flanges using bolts, the gasket fills surface irregularities and creates a tight seal. They are available in various shapes and materials, chosen based on the temperature, pressure, and chemical com...

Butterfly Valve Sleeve - India

The butterfly valve sleeve is a flexible, elastomeric or polymer lining fitted inside the valve body bore. It acts as the sealing surface against the rotating valve disc. When the disc closes, the sleeve compresses to prevent fluid leakage. The sleeve also protects the valve body from corrosion and wear.

Cup Type Diaphragms - India

Cup type diaphragms feature a concave, cup-like profile that allows for longer travel distance, increased flexibility, and efficient sealing under varying pressures. They are often used in pneumatic actuators, diaphragm pumps, and control valves where linear motion and pressure isolation are needed. This diaphragm...

O-Rings / Orings Kit - India

An O-ring is a loop of elastomer with a round (circular) cross-section, designed to be compressed between two surfaces to create a tight seal. They are one of the most common and cost-effective sealing solutions in mechanical systems.

O-ring kits typically contain dozens or hundreds of O-rings in various standard si...

Expansion Joints - India

An expansion joint is a specially designed component installed in pipes, ducts, or vessels to compensate for movementcaused by thermal changes, pressure fluctuations, mechanical vibration, or structural shifts. These joints prevent damage to pipes, pumps, valves, and equipment by relieving stress&nb...

PTFE Diaphragms - India

These diaphragms are widely used in diaphragm pumps, valves, and actuators, especially where other elastomers would degrade due to exposure to harsh chemicals, solvents, or high temperatures. PTFE diaphragms are often used alone or as a composite with a backing layer (such as rubber) to improve flexibility and mec...

Santoprene Diaphragms - India

Santoprene is a thermoplastic, a blend of rubber and plastic—that combines the elasticity of rubber with the processability and durability of thermoplastics. Santoprene diaphragms are commonly used in air-operated double diaphragm (AODD) pumps, valves, and other fluid-handling systems due to their long flex ...

Metal Bonded/ PTFE Laminated Diaphragms - India

These diaphragms feature a three-layer construction:



PTFE (Teflon) face: Provides a smooth, non-stick, chemically inert sealing surface that resists aggressive media such as acids, bases, and solvents.


Elastomer backing (e.g., EPDM, Viton, or NBR): Adds flexibility and ensures consistent movement and pressure response.
