Product Features

Automatic Condensate Discharge
The OPT-A/B Series electronic drain valve is designed for automatic condensate discharge in compressed air systems. It helps remove water and condensate from air compressors, air tanks, filters, dryers, and pipeline equipment.

Timer Controlled Drain Operation
The drain interval and discharge time can be adjusted according to the condensate volume and system operating condition. OFF time can be set from 0.5 to 45 minutes, and ON time can be set from 0.5 to 10 seconds.

2/2-Way Direct-Acting Valve Structure
The valve uses a 2/2-way direct-acting structure for reliable open and close control during condensate discharge. It is suitable for regular automatic draining in compressed air systems.

G1/2 Connection Options
OPT-A uses a G1/2 interface, while OPT-B provides G1/2 male inlet and G1/2 female outlet connection. Customers can select the correct type according to installation layout and pipeline connection.

IP65 Protection and LED Indicator
The timer section supports IP65 protection when installed correctly and includes an LED indicator for valve ON/OFF status. This helps operators check working status during installation and maintenance.

Brass and Stainless Steel Valve Body Options
The valve body is available in brass and stainless steel options. The correct material should be selected according to condensate condition, working environment, pressure, and system requirements.

OEM and Distributor Supply Friendly
HOMIPNEU supports model confirmation, bulk orders, export packaging, and OEM supply for air compressor service providers, compressed air system distributors, equipment builders, and industrial automation customers.

FAQ

What is the OPT-A/B Series electronic drain valve used for?
The OPT-A/B Series electronic drain valve is used for automatic condensate discharge in compressed air systems, including air compressors, tanks, filters, dryers, separators, and pipelines.

How does an electronic drain valve work?
An electronic drain valve uses a timer to open and close the valve automatically. The interval time controls how often the valve drains, and the discharge time controls how long the valve stays open.

What is the difference between OPT-A and OPT-B?
OPT-A uses a G1/2 interface, while OPT-B uses a G1/2 male inlet and G1/2 female outlet connection. The correct type should be selected according to the installation layout.

Can the drain interval be adjusted?
Yes. The timer interval time can be adjusted from 0.5 to 45 minutes, and the discharge time can be adjusted from 0.5 to 10 seconds.

What voltage options are available?
The valve section supports DC24V and AC220V options. The timer power supply supports 24–240V AC/DC, 50/60Hz, with AC380V available by special order.

Is the electronic drain valve waterproof?
The product supports IP65 protection when installed correctly. Proper installation, cable connection, and sealing are important for reliable operation.

Where should this drain valve be installed?
It can be installed on air compressor systems, air receivers, filters, dryers, separators, and low points of compressed air pipelines where condensate collects.

What should be confirmed before ordering?
Please confirm the model, inlet and outlet connection, voltage, pressure, condensate volume, discharge interval, discharge time, installation direction, cable connection, and order quantity.
