Bijur Delimon Lubrication Valves | Check, Shut-Off & Relief Valves

Bijur Delimon Valves

Lubrication valves are critical components in automatic lubrication systems that help regulate, isolate, and protect lubricant flow. Bijur Delimon valves are engineered specifically for lubrication applications so that systems deliver the right amount of lubricant, maintain pressure, and protect system integrity over continuous industrial use.

What Are Lubrication Valves?

Valves in a lubrication system control how and when lubricant moves through the circuit. Unlike generic hydraulic valves, lubrication valves are designed for the low-to-medium pressures and flow rates found in centralized oil or fluid grease systems. They help ensure lubricant only flows when needed and protect against backflow, pressure spikes, and system contamination.

Where Lubrication Valves Are Used

Lubrication valves are used in a wide range of industrial machinery where automated lubrication is required, including:

CNC machining centers and milling equipment
Progressive and dual-line lubrication systems
Rolling mills, presses, and forming machines
Conveyors, material handling lines, and indexing systems
Packaging, assembly, and automated production equipment

Types of Lubrication Valves

Check valves – Prevent backflow and maintain system pressure integrity.
Shut-off valves – Isolate sections of the system for maintenance or shutdown.
Relief valves – Protect against excessive pressure and ensure safe operation.
Flow control valves – Regulate lubricant flow rates for controlled delivery.

Why Lubrication Valves Matter

Properly selected lubrication valves help systems function reliably by:

Ensuring lubricant flows in the correct direction
Protecting the system from overpressure conditions
Isolating system segments for serviceability
Helping maintain a consistent delivery rate at each lubrication point

When to Use Valves in a Lubrication System

Systems that require controlled routing of lubricant
Systems with multiple zones or branches
Systems that need protection against backflow or pressure spikes
High-duty environments where reliability and uptime are critical

When Valves Are Not Needed

Very simple systems with only one downstream delivery point
Manual lubrication circuits with limited flow control requirements
Low-pressure, low-cycle machine lubrication with basic needs

How Valves Work in a Lubrication System

Lubrication valves connect to the distribution network of tubing and injectors. Check valves prevent reverse flow when pumps stop. Relief valves open when system pressure exceeds safe limits, protecting lines and components. Shut-off valves allow isolation for service without purging the entire system. Flow control valves help fine-tune delivery rates to match system needs.

Common Mistakes and Misapplications

Using hydraulic valves not rated for lubrication pressures and flow characteristics
Installing valves without considering direction of flow
Neglecting relief valve settings in high-pressure lubrication cycles

Frequently Asked Questions

What is a check valve in a lubrication system?
A check valve allows lubricant to flow in one direction only, helping maintain pressure and preventing unwanted backflow when the pump is off.

Why are relief valves used in lubrication systems?
Relief valves open when pressure exceeds a set threshold, protecting lines and components from potential damage due to overpressure.

Can lubrication valves be used with both oil and grease?
Yes, as long as the valve material and design are compatible with the lubricant type and viscosity used in the system.
