Orifice Valve

Orifice Valve

An Orifice Valve is a precision flow-control device used in oil and gas production, well testing, process plants, and pipeline systems to regulate, restrict, or measure the flow of liquids and gases. It incorporates a calibrated orifice that creates a controlled pressure drop, enabling accurate flow measurement and process control while maintaining system integrity.

Orifice valves are widely used in high-pressure and high-temperature (HPHT) environments and are designed for reliable operation in both onshore and offshore applications.

Applications

Oil and gas production facilities

Well testing operations

Pipeline flow measurement

Production manifolds

Chemical injection systems

Working Principle

An Orifice Valve controls fluid flow by forcing the fluid through a precisely machined orifice.

Process fluid enters the valve body.

The fluid passes through the calibrated orifice.

A pressure drop is created across the orifice.

The pressure differential can be used to regulate or calculate the flow rate.

The controlled fluid continues downstream while maintaining stable operating conditions.

This design provides accurate flow restriction and dependable process control in high-pressure systems.

Inspection Before Installation

Inspect the valve body for mechanical damage or corrosion.

Verify orifice size and pressure rating.

Check valve operation and movement.

Inspect sealing surfaces and seats.

Confirm thread or flange compatibility.

Perform hydrostatic and pressure testing before commissioning.

Maintenance

Conduct routine visual inspections.

Clean the orifice plate regularly to prevent blockage.

Replace worn seals and seats as required.

Lubricate moving parts where applicable.

Pressure-test the valve after maintenance.

Store in a clean, dry environment with protective covers installed.
