CRIDENG HPA Regulator Valve (M18x1.5 Thread) Instruction Manual

1. Introduction

This manual provides comprehensive instructions for the safe and effective use of your CRIDENG HPA Regulator Valve. This device is engineered to precisely control the High-Pressure Air (HPA) output from compatible tanks, featuring an integrated on/off valve and suitability for PCP fuel tank regulator leak testing. Please read this manual thoroughly before installation and operation to ensure proper function and safety.

2. Safety Information

• Always wear appropriate personal protective equipment, including eye protection, when handling HPA tanks and regulators.
• Ensure all connections are secure and leak-free before pressurizing the system. Use a leak detection solution to verify.
• Never exceed the maximum rated input pressure of 3000 psi for the regulator or the maximum pressure rating of your HPA tank (up to 4500 psi / 300 bar / 30 MPa).
• Do not modify the regulator or use it for purposes other than its intended design.
• Keep the regulator and HPA tanks out of reach of children and unauthorized personnel.
• Depressurize the system completely before disconnecting any components.

3. Product Overview

The CRIDENG HPA Regulator Valve is a robust, stainless steel component designed for reliable pressure regulation. It features an adjustable output pressure range and an on/off valve for precise control.

Key Features:

• Adjustable Pressure: Output pressure can be adjusted from 0 to 2800 psi.
• Tank Compatibility: Designed for use with HPA tanks featuring 5/8-18UNF or M18x1.5 threads, supporting tank pressures up to 4500 psi / 300 bar / 30 MPa. This specific model features an M18x1.5 input thread.
• Precision Control: An integrated on/off valve allows for better control over HPA output.
• Durable Construction: Made from high-quality stainless steel for longevity and reliability.
• Output Thread: G1/2 (0.825-14NGO) for connecting to various HPA systems.

4. Setup

Follow these steps for proper installation of your HPA Regulator Valve:

1. Inspect Components: Before installation, carefully inspect the regulator, O-rings, and threads for any damage or debris. Ensure the O-rings are properly seated.
2. Attach to HPA Tank: Screw the regulator's M18x1.5 input thread onto your compatible HPA tank. Hand-tighten first, then use an appropriate wrench to secure it firmly. Do not overtighten.
3. Connect Output Device: Attach your HPA-powered device or hose to the G1/2 (0.825-14NGO) output thread of the regulator. Ensure this connection is also secure.
4. Initial Pressure Setting: Before opening the tank valve, ensure the regulator's on/off valve is in the 'OFF' position (typically by turning the knob counter-clockwise until it stops). If your variant includes a pressure gauge, ensure it reads zero.
5. Leak Test: Once all connections are made, slowly open the HPA tank valve. Apply a leak detection solution (e.g., soapy water) to all connections. Look for bubbles, which indicate a leak. If leaks are detected, close the tank valve, depressurize the system, and re-tighten connections or replace O-rings as necessary.

5. Operating Instructions

Once the regulator is securely installed and leak-tested, follow these steps for operation:

1. Open Tank Valve: Slowly open the valve on your HPA tank. The regulator's input pressure gauge (if present) should show the tank's pressure.
2. Activate Regulator: Turn the regulator's on/off valve knob clockwise to the 'ON' position. This will allow air to flow through the regulator.
3. Adjust Output Pressure: To adjust the output pressure, use the adjustment mechanism (if present, typically a screw or knob) on the regulator. Turn clockwise to increase pressure and counter-clockwise to decrease pressure. Monitor the output pressure gauge (if present) to set the desired pressure within the 0-2800 psi range.
4. Monitor Pressure: Continuously monitor both input and output pressures during operation to ensure they remain within safe limits.
5. Shut Down: To cease operation, first turn the regulator's on/off valve knob counter-clockwise to the 'OFF' position. Then, close the valve on your HPA tank. Finally, depressurize any remaining air in the system by activating your HPA-powered device until all air is expelled.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your HPA Regulator Valve.

• Cleaning: Keep the regulator clean and free from dirt, dust, and debris. Use a soft, dry cloth for cleaning. Do not use harsh chemicals or solvents.
• O-Ring Inspection: Periodically inspect all O-rings for wear, cracks, or damage. Replace any worn or damaged O-rings immediately with appropriate replacements.
• Thread Inspection: Check the threads on both the regulator and your HPA tank for any signs of damage or cross-threading. Ensure threads are clean before assembly.
• Storage: When not in use, store the regulator in a clean, dry, and cool environment, away from direct sunlight and extreme temperatures. Ensure the system is fully depressurized before storage.
