China Screw Air Compressor Minimum Pressure Valve Manufacturer
The Minimum Pressure Valve (Part No. 23378011) is a critical safety and performance component in oil-injected screw air compressors. Designed to regulate the minimum internal pressure during start-up and normal operation, this valve ensures stable oil circulation, prevents backflow, and protects the compressor elements from premature wear. Manufactured with high-precision components and durable sealing materials, it delivers reliable operation even under demanding industrial conditions.

This minimum pressure valve is specifically engineered for use in oil-lubricated rotary screw air compressors. Its main purpose is to maintain a preset minimum system pressure — typically around 4–6 bar — allowing sufficient oil flow to lubricate and cool the compressor before the air system reaches full load. Once the desired pressure is achieved, the valve opens gradually to supply compressed air downstream.
The body is made of high-strength brass or anodized aluminum alloy, featuring excellent corrosion resistance and thermal stability. Internal components, such as the piston and spring assembly, are precision-machined and surface-treated to prevent sticking and wear, ensuring consistent performance throughout its service life.
Key Features & Technical Advantages
- Accurate Pressure Control: Factory-calibrated to maintain stable minimum system pressure for optimal compressor operation.
- High-Quality Brass Construction: Excellent resistance to corrosion, oil vapor, and heat ensures long service life.
- Reliable Sealing Performance: Utilizes oil-resistant O-rings and precision-ground sealing surfaces to prevent leakage.
- Smooth Pressure Transition: Gradual opening mechanism minimizes system shock and reduces wear on airend bearings.
- Easy Maintenance: Modular design allows for quick disassembly, inspection, and cleaning without special tools.
Working Principle
When the compressor starts, the minimum pressure valve remains closed, trapping air and oil within the system to establish the required internal pressure. As the pressure rises to the preset threshold (e.g., 4–5 bar), the valve opens automatically, allowing compressed air to flow into the air receiver. During shutdown or unloading, it closes immediately to prevent backflow and oil loss. This automatic operation ensures lubrication stability and extends compressor life.
Applications
- Oil-injected rotary screw air compressors in industrial plants
- Automotive and manufacturing air systems
- Energy-efficient compressed air solutions
- Equipment requiring reliable lubrication and system protection
Quality Assurance
Every 23378011 minimum pressure valve undergoes a full pressure endurance test, leak detection test, and opening/closing cycle test before packaging. Each batch is tested for consistent response pressure and flow rate to guarantee compatibility with OEM compressor performance standards.
Maintenance Tips
- Inspect the valve every 2000–3000 running hours for dirt, oil sludge, or carbon deposits.
- Replace seals if air or oil leakage is detected around the valve body.
- Always use compatible compressor oil to prevent varnish buildup that could restrict valve movement.
- If the valve opens too early or too late, check spring integrity and replace if weakened.

Common FAQs
Q1: What happens if the minimum pressure valve fails?
A: Failure can lead to insufficient oil pressure during start-up, resulting in inadequate lubrication, overheating, and accelerated wear of the airend bearings.
Q2: How often should the valve be replaced?
A: Under normal operating conditions, it is recommended to inspect and, if necessary, replace the valve every 8,000–10,000 hours, or during major compressor overhauls.
Q3: Can this valve be cleaned and reused?
A: Yes. If the valve shows no mechanical damage, it can be cleaned with non-corrosive solvent and compressed air. Ensure the sealing surfaces remain smooth and intact before reinstallation.
Q4: Is this part interchangeable with OEM versions?
A: Yes, this valve is fully compatible with OEM specifications and designed to meet or exceed factory performance standards.
Q5: How can I verify compatibility with my compressor model?
A: Provide your compressor brand, model number, and serial plate information. Our technical support team will confirm compatibility before shipment.
