Wafer Type Check Valves Manufacturer in India

Forex Valves manufactures and supplies Wafer Type Check Valves designed for reliable backflow prevention in industrial piping systems. These valves are engineered according to API 594 design standards and tested as per API 598 to ensure dependable performance, tight shut-off, and long service life across different process applications.

As an experienced Wafer Type Check Valve Manufacturer in India, we provide wafer check valves suitable for water treatment, chemical processing, power plants, HVAC systems, oil & gas, refineries, and other industrial pipeline applications. Our valves are available in different materials, pressure ratings, sizes, and seat configurations to meet specific project requirements.

What Are Wafer Type Check Valves?

A Wafer Type Check Valve is a compact non-return valve installed between pipeline flanges to prevent reverse flow of fluids. Unlike traditional flanged check valves, wafer designs offer a lightweight and space-saving solution while maintaining efficient flow control.

These valves automatically allow fluid flow in one direction and close when the flow reverses, protecting pumps, compressors, pipelines, and other equipment from damage caused by backflow.

Wafer Type Check Valve Design and Construction

Forex Valves manufactures wafer check valves with a wafer type end connection suitable for installation between compatible flanges. The compact construction reduces installation space, weight, and maintenance requirements compared to conventional valve designs.

API 594 Compliant Design API 594 compliant design for wafer and lug-type check valve requirements.
API 598 Testing Pressure testing and leakage performance verification as per API 598.
Compact Wafer Design Space-saving construction for installation between compatible pipeline flanges.
Low Pressure Drop Designed to support efficient fluid movement through the pipeline system.
Fast Closing Fast closing action helps minimize reverse flow and water hammer effects.
Installation Flexibility Suitable for horizontal and vertical pipeline installations depending on application requirements.

Materials Available for Wafer Check Valves

Material selection plays an important role in valve performance, corrosion resistance, and operating life. Forex Valves offers wafer type check valves manufactured using industry-standard materials.

Carbon Steel Wafer Check Valve

CS A-216 Gr. WCB is commonly selected for general industrial applications where strength, durability, and cost efficiency are required. Carbon steel wafer check valves are suitable for water, steam, oil, and various industrial fluid systems.

Stainless Steel Wafer Check Valve

SS A-351 Gr. CF8M provides enhanced corrosion resistance and is preferred for aggressive chemical environments, marine applications, food processing, and pharmaceutical industries.

Seat Material Options

Different operating conditions require different sealing materials. Available seat options include:

EPDM: Suitable for water, cooling systems, and general fluid applications.
VITON: Provides resistance against high-temperature fluids, oils, and chemicals.
NITRILE: Commonly used for oil and fuel-related applications.
NEOPRENE: Suitable for applications requiring weather and chemical resistance.
PTFE: Preferred for highly corrosive chemical applications due to excellent chemical resistance.
GFT: Used where reinforced sealing performance is required.

The correct seat selection depends on fluid type, temperature, pressure, and operating conditions.
