MPV-50T Minimum Pressure Valve

The MPV-50T Minimum Pressure Valve is an important component in an oil-injected screw compressor. Its primary function is to maintain minimum pressure within the separator system before allowing compressed air to flow into the downstream air circuit.

During compressor start-up, the valve helps the compressor build the required internal pressure. Once the pressure reaches the valve’s operating range, it opens to allow compressed air to pass through the system. The valve also helps prevent reverse airflow when the compressor stops.

The MPV-50T is commercially listed as a minimum pressure valve for screw air compressors, and the model is also used in various compressor applications.

Technical Specifications

Important: Do not publish dimensions, pressure settings, thread sizes or compressor compatibility as universal specifications unless they are verified against the exact MPV-50T version. Different manufacturers can use similar MPV-50T designations.

One technical source lists an MPV-50T version with approximately 4–5 bar operating pressure and 15 bar maximum pressure, but these values should be treated as version-specific rather than universal for every MPV-50T.

Compatible Compressor Applications

The MPV-50T is intended for screw air compressor applications.

Some published compressor documentation identifies MPV-50T-family valves in specific compressor systems. For example, compressor documentation lists MPV-50T-FS as a minimum pressure valve for an NxV75-90 application, while another equipment manual identifies MPV-50T-Y in 75/100/150 HP compressor equipment. These are related model variants and should not be treated as automatic compatibility for the standard MPV-50T.

Before ordering, verify:

• Compressor brand
• Compressor model
• Compressor horsepower/kW
• Existing valve model
• Valve dimensions and connection
• Part number on the old valve
• Compressor serial number, if available

Main Functions

The MPV-50T Minimum Pressure Valve helps:

• Maintain minimum separator pressure
• Support correct compressor start-up
• Control compressed-air flow
• Reduce reverse airflow during shutdown
• Support proper oil circulation in oil-injected compressors
• Maintain stable compressor operation
• Protect the air-oil separation system from unsuitable operating conditions

Why Replace a Minimum Pressure Valve?

A worn or malfunctioning MPV can contribute to:

• Incorrect compressor pressure
• Slow pressure build-up
• Unstable compressor operation
• Excessive oil carryover
• Airflow problems
• Reverse flow during shutdown
• Increased compressor maintenance requirements

If the valve is sticking, leaking or failing to maintain the required pressure, replacement or servicing may be necessary.

How to Verify MPV-50T Before Ordering

For the correct replacement, compare your existing valve with the MPV-50T carefully.

Please check:

1. Part/model number
2. Valve body design
3. Connection type
4. Overall dimensions
5. Mounting arrangement
6. Pressure requirement
7. Compressor model
8. Compressor serial number

Best option: Send Airmake Solution a clear photograph of your existing valve together with the compressor model and serial number. This can help confirm compatibility before ordering.

FAQ

1. What is MPV-50T?

MPV-50T is a Minimum Pressure Valve used in suitable screw air compressor systems to control and maintain minimum internal pressure.

2. What is the function of a Minimum Pressure Valve?

It helps the compressor build and maintain the required internal pressure before allowing compressed air to flow into the downstream system.

3. Where is MPV-50T used?

MPV-50T is listed for use in screw air compressor applications, particularly in oil-injected compressor systems.

4. Is MPV-50T suitable for every screw compressor?

No. MPV-50T should not be considered universally compatible. Connection, dimensions, pressure requirements and compressor design must be checked before installation.

5. How can I confirm the correct MPV-50T?

Send your compressor model, serial number and a clear photo of the existing minimum pressure valve to verify the correct replacement.

6. What happens if the minimum pressure valve is faulty?

A faulty MPV can cause pressure-control problems, unstable operation, slow pressure build-up or other compressor performance issues.

7. Can I order MPV-50T in India?

Yes. Airmake Solution can assist with availability, pricing and delivery for compressor spare parts across India.
