Why Use Manual Shut-Off Valves?

Manual shut-off valves provide precise control over refrigerant flow during charging and recovery operations. The quarter-turn ball valve allows instant on/off control, preventing refrigerant venting when disconnecting hoses. This is essential for EPA compliance and professional refrigerant handling practices. The flexible hose design allows easy routing and positioning during service operations.

Benefits:

• Quarter-Turn Operation – Fast, easy on/off control
• Prevents Venting – Close valve before disconnecting to contain refrigerant
• EPA Compliant – Meets refrigerant containment standards
• Flexible Hose – Easy routing and positioning
• High-Pressure Rated – Handles R410A and all refrigerants
• Professional Quality – Built for daily commercial use
• Red Colour Coding – Easy identification for high-side use
• Universal Compatibility – Standard 1/4" flare fittings

How to Use:

1. Connect valve to manifold high-side (red) port
2. Connect other end to system service port or refrigerant cylinder
3. Open valve (quarter-turn) to allow refrigerant flow
4. Proceed with charging or recovery operation
5. Close valve (quarter-turn) before disconnecting
6. Disconnect hose with minimal refrigerant loss
7. Valve contains refrigerant in hose

EPA Refrigerant Containment Requirements:

EPA regulations require technicians to minimise refrigerant venting during service operations. Manual shut-off valves are essential for compliance, allowing technicians to close the valve before disconnecting hoses, thereby containing refrigerant and preventing atmospheric release.

Quarter-Turn Ball Valve Operation:

• Open Position – Handle parallel to hose, refrigerant flows freely
• Closed Position – Handle perpendicular to hose, refrigerant flow stopped
• Quick Operation – 90° turn from open to closed
• Positive Shut-Off – Ball valve provides complete seal

High-Side vs Low-Side Valves:

• High-Side (Red - 90265) – For discharge/high-pressure connections (this product)
• Low-Side (Blue) – For suction/low-pressure connections
• Centre (Yellow) – For service/centre port connections

Maintenance:

• Inspect valve operation regularly
• Check for leaks at connections
• Lubricate valve occasionally with refrigerant oil
• Replace if valve becomes difficult to operate
• Keep hose clean and free from damage
• Store properly when not in use

Safety Notes:

• Always close valve before disconnecting hoses
• Verify valve is fully open during charging/recovery
• Check for leaks after connection
• Wear safety glasses when handling refrigerant
• Follow EPA refrigerant handling regulations
