A Lift Check Valve is one of the most reliable solutions to prevent backflow in industrial fluid systems. Known for its strong sealing performance, durability, and suitability in high-pressure applications, the lift type check valve is widely used in industries ranging from petroleum and chemical processing to power generation and water treatment. In this comprehensive guide, we will explain the definition, working principle, types, applications, and selection criteria of lift check valves, and why choosing a trusted manufacturer like LIXIN can make a difference for your business.

2 What is a Lift Check Valve?

2-1 Definition

A lift type check valve (also called check valve lift type) is a non-return valve that allows fluid to flow in one direction while automatically preventing reverse flow. It is commonly installed in high-pressure and clean fluid systems to protect pumps, compressors, and pipelines from damage caused by backflow.

2-2 Operating Principle

The valve works automatically without external force:

Forward flow : When inlet pressure exceeds cracking pressure, the disc, or piston, lifts off the seat, allowing fluid to pass.
Reverse flow : When pressure drops or reverses, the disc falls back onto the seat, ensuring tight sealing.

This simple but effective design makes the piston lift type check valve highly reliable for critical operations.

2-3 Main Features and Advantages

Automatic operation with no actuator required.
Excellent sealing to prevent backflow.
Durable design suitable for high-pressure and high-temperature systems.
Versatile installation : supports both horizontal and vertical lift check valve installation.
Low maintenance requirements compared to swing check valves.

2-4 Application Scenarios

Petroleum & Chemical Industry – fluid control in pipelines.
Electric Power Plants – steam and cooling water systems.
Mining & Metallurgy – slurry and processing lines.
Pharmaceutical & Food – clean fluid applications.
Water Treatment & Sewage Systems – reliable backflow prevention.

2-5 Potential Disadvantages

Higher pressure drop compared to swing check valves.
Not suitable for slurry or dirty fluids (risk of clogging).
Limited to relatively smaller pipe sizes compared to swing type.

3 Types of Lift Check Valve

3-1 Piston Lift Type Check Valve

The check valve piston type lift uses a piston as the closure element. It is ideal for steam and gas systems, offering excellent sealing and durability. Many piston lift type check valve manufacturers, including LIXIN, design these valves to meet international standards.

3-2 Ball Lift Type Check Valve

This type employs a spherical ball as the disc. Best for low-pressure and clean fluid systems, it offers simple operation and easy maintenance.

3-3 Vertical Lift Check Valve

Specially designed for vertical lift check valve vertical installation, this type is ideal for upward flow applications. Gravity assists in disc closure, making it efficient in preventing reverse flow.

3-4 T-Type Lift check Valve

A compact design where the disc moves vertically in a straight body. Best suited for horizontal pipelines requiring tight sealing in limited space.

3-5 Y-Type Lift Check Valve

Featuring a 45° angled body, this design reduces pressure drop and minimizes wear. It is commonly used in high-velocity pipelines where durability and efficiency are critical.

4 Material and Selection Considerations

When selecting a lift type check valve, material choice plays a key role:

Carbon Steel – general industrial applications.
Stainless Steel – corrosive or high-temperature environments.
Bronze / Brass – clean water systems.
Alloy Steel – extreme temperature and pressure conditions.

Always ensure compliance with lift type check valve design standards such as API 6D, ASME B16.34, or DIN EN standards.

5 Maintenance and Inspection

To extend valve life and ensure performance:

Regularly inspect disc and seat for wear.
Ensure proper cleaning during lift type check valve installation.
Check alignment and lift type check valve dimensions before operation.
Replace parts only with genuine spares from trusted piston lift type check valve suppliers.

6 Key Factors in Selecting a Lift Check Valve

System pressure and temperature.
Fluid type (steam, water, gas, chemicals).
Pipeline orientation (vertical or horizontal).
Compliance with standards.
Supplier reputation – only choose reliable piston lift type check valve manufacturers with proven expertise.
