Overview

The document provides detailed technical specifications, construction details, ordering information, and precautions for the Series AQ Quick Exhaust Valves and the Series AQ240F/340F Quick Exhaust Valves with One-touch Fittings. These valves are designed for pneumatic systems to enable rapid exhaust of air, improving system response times.

1. Product Models and Specifications

• Series AQ Models: AQ1500, AQ1510, AQ2000, AQ3000, AQ5000 with various port sizes (M5 x 0.8, 1/8", 3/4", 1/2", 1/4") and effective areas ranging from 14 mm² to 135 mm².
• Operating Parameters: Proof pressure up to 1.5 MPa, maximum operating pressure 0.7 to 1 MPa, minimum operating pressure 0.05 to 0.1 MPa, ambient and fluid temperature range -5 to 60°C (with options for -30 to 60°C and -5 to 80°C for specific models).
• Materials: Bodies made from zinc die-casted, brass, aluminum die-casted; seals typically NBR or HNBR; electroless nickel plating on brass parts for corrosion resistance.
• Mass: Varies by model from approximately 2.8 g to 180 g.

2. Construction and Components

The valves consist of key components such as the body, guide, cover, valve, and O-rings. Materials include brass, zinc die-casted metal, aluminum, and various elastomers for seals. The document lists part numbers and materials for replacement parts, emphasizing durability and compatibility.

3. Design and Selection Considerations

• Ensure differential pressure between IN and OUT ports exceeds minimum operating pressure to avoid insufficient exhaust or noise due to vibration.
• Avoid residual or back pressure on the IN side to maintain valve performance.
• Match the effective area of the IN side piping or solenoid valve to the valve size to prevent flow restrictions.

4. Ordering Information

Models are identified by port size, thread type (Metric M5, Rc, NPT, G), and options such as high or low temperature ratings. The document provides a coding system for ordering, including symbols for diaphragm or lip valve types and silencer or exhaust port fittings.

5. Series AQ240F/340F Quick Exhaust Valves with One-touch Fittings

• Specifications: Designed for tubing outer diameters of 4 mm, 6 mm, and 1/4", with effective areas from 1.7 mm² to 4 mm².
• Operating Conditions: Proof pressure 1.5 MPa, max operating pressure 1 MPa, minimum operating pressure 0.1 MPa, temperature range -5 to 60°C.
• Materials: Bodies made of PBT resin, brass seat rings and valve seats with electroless nickel plating, stainless steel silencer covers, and elastomer seals (NBR, HNBR).
• Features: Space-saving design, rectilinear IN-OUT tubing connections, lightweight resin body, options with silencer or exhaust port fittings.

6. Dimensions and Weights

Detailed dimensional data is provided for all models, including lengths (L1-L9), diameters (D1, D2), and weights ranging from approximately 10 g to 52 g depending on model and fitting type.

7. Precautions and Safety

• Refer to safety instructions and flow control equipment precautions before handling.
• Ensure no residual or back pressure on the IN side to prevent noise and vibration.
• Maintain proper differential pressure and piping effective area for optimal valve operation.
• When using soft nylon or polyurethane tubing, observe maximum operating pressure limits.

Summary

The Series AQ and AQ240F/340F Quick Exhaust Valves offer a range of sizes and configurations suitable for pneumatic systems requiring rapid exhaust capabilities. Their robust construction, variety of port sizes, and options for silencers and fittings make them versatile components. Proper selection and installation according to the specified parameters and precautions ensure reliable and noise-free operation.
