Top Check Valve Supplier in India – Speciality Valve

In fluid control systems it is of great importance to protect pumps, compressors and pipelines from damage which we achieve via the use of check valves. This is the area where check valves prove their vital role. Speciality Valve is known for check valve supplier in India, presents a large scale of non-return valve solutions to the oil and gas, chemical processing, water treatment, power generation, and HVAC industries. These valves are simple, reliable, and very effective in what they do across many applications.

How Check Valve Works

A check valve which is also known as a non-return valve allows for the flow of fluid in a single direction only. It acts automatically via pressure differences and does not require manual intervention.

1. Forward Flow: When on the inlet side the fluid pressure is great the disc or ball moves off the seat which in turn allows for flow.
2. Reverse Flow: Upon occurrence of backflow the disc goes to its seat which in turn seals the passage and stops reverse movement.

This is what makes check valves a must for systems which have pumps and compressors they prevent the machinery from running in reverse and from damage at shutdown.

Why Check Valve is Used?

In many cases Industries use check valves for:

• Backflow Prevention: Protecting the pumps, the pipelines, and the instruments.
• Maintaining Prime: In maintaining fluid in the line when the pump is off.
• Safety: Prevents the contamination of feed stocks in chemical and pharmaceutical industries.
• Durability: Runs on its own without external power or actuator.
• Versatility: Available in swing check valve, ball check valve, piston check valve, and wafer check valve types for various applications.

In potable water systems, in oil pipelines, in HVAC which also means heating, ventilation, and air conditioning systems, check valves play the role of ensuring system integrity and efficiency.

Can Check Valve be Installed Vertically?

Yes in some cases check valves may be installed in a vertical position but it is based on the valve type and application.

• Swing Check Valves do not do well in vertical lines which see flow down as gravity does not properly close the disc.
• Lift Check and Ball Check Valves may be installed in a vertical position which the design intent to take advantage of gravity or spring assist for proper closure.
• Wafer Check Valves are designed for use in both horizontal and vertical applications.
• Proper installation is key to prevent leakage, water hammer, and reduced efficiency.

Check Valve Without Spring

A check valve that does not have a spring uses gravity or back pressure for closing instead of a mechanical spring. These valves tend to be:

1. Swing Check Valves: Where the disc pivots freely.
2. Ball Check Valves: Where the ball falls by gravity to prevent reverse flow.

They are economical and easy to use but in fast closing applications may not perform as well which is when a spring loaded mechanism is used.

Check Valve Vs Non-Return Valve

The terms check valve and non-return valve (NRV) are at time used synonymously. But there are fine lines in their definition:

In the system we present, all check valves are non-return valves, but not all NRVs are what may be considered industrial-grade check valves.

Types of Check Valves Available

A preeminent check valve supplier in India provides a variety of designs for specific industrial needs:

1. Swing Check Valve Hinged disc opens up for flow, closes in case of backflow.
2. Ball type Check Valve – which uses a ball to prevent reverse flow, common in slurry and viscous fluids.
3. Piston action check valve which has a disc that moves up and down via flow pressure.
4. Wafer Type Check Valve For use in small space pipelines.
5. Dual Plate Check Valve Equipped with two spring loaded plates which quickly shut down to reduce water hammer.

Industries Using Check Valves

• Water and Waste Water Treatment Plants Reducing contamination and backflow.
• Oil and Gas We are into pumps and compressors in crude and gas pipeline.
• Power Plants Maintaining steam flow in one direction.
• Chemical Industry Preparing for the issue of cross-contamination of aggressive fluids.
• HVAC Systems which include maintaining of chilled water circulation and prevention of reverse flow.

Advantages of Check Valves

• Automatic Operation – no manual input required.
• Low upkeep basic design, few moving parts.
• Wide Range of Uses for gases, liquids, and slurries.
• Energy Efficiency Reduces loss in pumps and compressors.
• Compact Products Wafer check valves and inline check valves for your space savings needs.
