Valves are essential components in every industrial, commercial, and residential pipeline system. Among the wide variety, check valves and butterfly valves are the most widely used due to their simple operation, durability, and affordability. This guide explains their types, functions, price ranges, and manufacturer details in India for 2025.
What is a Check Valve?
A check valve is a one-way valve that prevents reverse flow in pipelines. It is also known as a non-return valve (NRV). Check valves are commonly used in water pumps, compressors, hydraulic systems, and fuel pipelines.
- Prevents backflow
- Protects pumps and compressors
- Maintains pressure in pipelines
Types of Check Valves
Water Pump Check Valve
Used to prevent backflow in domestic and industrial water pump systems.
Spring Loaded Check Valve
Compact design with a spring mechanism, ensures quick closure.
Swing Check Valve
Has a disc that swings open and closes with back pressure. Common in large pipelines.
Pilot Operated Check Valve
Used in hydraulic systems for precise pressure control.
Feed Check Valve
Installed in boilers to regulate water entry.
Ball Type Check Valve
A ball-shaped disc blocks backflow; often used in slurry applications.
Pneumatic & Hydraulic Check Valves
Used in automation and heavy machinery where air or hydraulic fluids are used.
Each type has specific applications, advantages, and cost implications.
