3726522220 AVENTICS Pressure Reducing Valve 10 bar

Product Overview

⚠️ Brand and Model Note: Verified sources confirm that 3726522220 belongs to the AVENTICS brand, now part of the Emerson group, formerly the Bosch Rexroth pneumatic product line. While some distributors describe this model as a “3/2 solenoid valve”, the user has specified it as part of the 3726/3730/3760/3750 series pneumatic pressure reducing valves. The following content is based on the general specifications of AVENTICS pneumatic pressure reducing valve series.

3726522220 is a pneumatic pressure reducing valve from the AVENTICS 3726/3730/3760/3750 series. This series is widely used in marine main engine remote control systems, offshore engineering pneumatic control systems, and various industrial pneumatic applications for precise pressure regulation and stabilization.

These pneumatic pressure reducing valves feature a modular design with diaphragm-type pressure regulator construction, achieving precise downstream pressure control through dynamic balance between spring force and outlet pressure. The compact valve design supports standard in-line installation for direct integration into pneumatic control panels and piping systems.

Specifically designed for marine and offshore harsh environments, the series features high-strength alloy housing and salt-spray resistant special sealing materials, effectively withstanding engine room heat, humidity, salt spray corrosion, and continuous vessel vibration.

Our complete range of AVENTICS pneumatic pressure reducing valves strictly adheres to OEM technical standards, achieving 100% direct interchangeability with original components. Every unit undergoes 100% simulated operating condition bench testing prior to shipment, ensuring performance parameters are fully consistent with genuine AVENTICS products. Direct replacement significantly reduces equipment downtime and maintenance costs.

Expert Maintenance Tips

1. Verify Model and System Compatibility Prior to Installation

AVENTICS 3726/3730/3760/3750 series offers multiple port sizes and pressure range options. Confirm that the selected model’s port size, operating pressure range (0.5–10 bar) , and adjustment range (0.5–8.5 bar) cover system requirements prior to installation.

2. Correct Installation Orientation

This series recommends vertical installation. Observe flow direction markings on the valve body—inlet and outlet must be correctly oriented. Incorrect installation will prevent the valve from functioning properly.

3. Pressure Setting and Commissioning

• Set the outlet pressure via the adjustment knob (clockwise to increase, counterclockwise to decrease)

• Observe the outlet pressure gauge until the target value is reached

• During commissioning, start from low pressure and gradually increase to the set value to avoid pressure shock damaging downstream components

4. Air Quality Management

Pneumatic pressure reducing valves require certain air quality standards. Install filters and coalescing separators upstream of the pressure reducing valve to ensure compressed air is clean, dry, and oil-free, extending valve service life.

5. Ambient Temperature Control

This series supports ambient temperatures of +5°C to +60°C. Operating outside this range may result in reduced regulation accuracy or accelerated seal aging. Appropriate insulation or cooling measures should be taken under extreme temperature conditions.

6. Periodic Maintenance and Inspection

Perform functional checks every 2,000 operating hours or annually: verify outlet pressure stability, adjustment function, and external leakage. If abnormal pressure fluctuation, adjustment failure, or leakage is observed, arrange for servicing or replacement.
