Product Description:

Advantages and features of Anvotech pneumatic pilot valves

‌High-precision regulation and control capabilities‌

The pilot pressure reducing structure is adopted to accurately regulate the main valve pressure through a small direct-acting valve to reduce output fluctuations. The flow control accuracy can reach within ±1%, which is suitable for the dynamic regulation requirements of complex industrial automation systems.

The nozzle baffle amplification link is integrated, and the main valve can respond quickly with a small input signal, which is suitable for high-sensitivity control scenarios.

‌Modular and compatible design‌

The valve island adopts lightweight engineering plastics and inclined valve core structure design, which reduces the weight by more than 30%.

The compact module supports distributed installation. Arrangement close to the actuator can shorten the length of the air pipe and reduce pressure loss.

Compatible with multiple bus protocols (such as CAN, PROFINET), supports tool-free rapid disassembly and assembly of expansion function units, and meets the flexible configuration requirements of automated handling systems.

‌Durability and safety‌

Key components are made of wear-resistant engineering plastics and corrosion-resistant coatings. The seals have a temperature resistance range of -25~60℃, which can adapt to harsh working conditions such as high temperature and high dust.

Through explosion-proof certification, it can be used with flameproof electrical components to meet the fire and explosion requirements of hazardous scenes such as chemical industry and metallurgy.

‌Energy consumption optimization‌

The optimized flow channel design reduces dead zone, reduces compressed air consumption by 20%, and cooperates with the pressure zoning function to realize on-demand gas supply and reduce energy waste.

Precautions for use

‌Installation and commissioning specifications‌

The main valve and pilot valve must be installed vertically. When the inclination angle exceeds 5°, a support frame must be added to avoid leakage caused by uneven force on the valve core.

Before commissioning, the pipeline must be thoroughly flushed to remove welding slag impurities to prevent clogging of the precision throttle hole of the pilot valve.

‌Operation and load management‌

When adjusting the pressure, first turn the knob counterclockwise to zero, and then gradually increase the pressure to the target value to avoid instantaneous high pressure impact on the diaphragm assembly.

The working pressure must not exceed the rated value marked on the nameplate (such as 175 bar), and a safety relief valve protection system must be installed for overpressure conditions.

‌Maintenance and troubleshooting‌

Check the wear of the pilot valve diaphragm and nozzle baffle every 500 hours. In high temperature environments, the lubricating oil replacement cycle needs to be shortened to 300 hours.

It is strictly forbidden to operate with power on during the maintenance of explosion-proof products. The flatness and sealing of the explosion-proof surface must be restored after disassembly.

‌System redundancy design‌

It is recommended to configure dual pilot valve redundant control for key process circuits. When the main valve fails, it can be switched to the backup valve to maintain production continuity.

Regularly calibrate the synchronization of the electrical positioner signal and the valve position feedback. If the deviation exceeds ±2%, it needs to be recalibrated.

(Note: The advantages and features focus on control accuracy, modularity and safety; the precautions cover the core points of installation and commissioning, pressure management and redundant design)
