Description

Product Overview

304 stainless steel no-loss electrical drain valve for air receiver tank

Condensed water will be generated in the process of compressed air system. In most cases, the condensate also contains oil and granular impurities. If the condensed water can not be discharged timely, it will wear and rust downstream equipment, and affect compressed air quality.If the drain valve is leaked, it will cause expensive compressed air loss, and make the air compressor working at full load for a long time, thus consume more electricity and increase more maintenance work.
SD Series Smart Drain adopts high quality level sensor and intelligent control system, it can effectively discharge condensate water according to its actual amount so as to avoid loss of compressed air.

FEATURES AT A GLANCE
Suitable for all kinds of condensate water

Real-time discharge condensate according to liquid level without air loss

Large diameter of drain hole with strainer to avoid clog

Indicator lights visually show operation status, with alarm and manual testing function

Robust, corrosion resistant stainless steel housing


HOW IT WORKS

Condensate water flows into storage tank from inlet, and water level of the tank continues to rise.

When water level rises to induction point, the sensor sends a signal and the solenoid valve opens to discharge condensed water.

When condensed water is nearly exhausted, the solenoid valve will automatically close, leaving a small amount of condensed water, forming a water seal. 

 When drain valve fails and water level is too high, the sensor inducts by real-time, drain valve enters self-cleaning drainage mode automatically, and can outputs alarm signal remotely.

Two kinds of alarm contacts of normally open(switch on when alarm) and normally closed(switch off when alarm)  are available at the same time
Load of alarm contacts
Max. 62. 5VA at alternating current, Max. 60W at direct current

Optional Accessories
Ball Valve Strainer
BVS combines filter and ball valve together. It can not only filter impurities in condensed water, but
also cut off air source when cleaning and maintaining drain valve.

Anti-block Joint
Some equipment containers do not have an available port to set an air balance pipe. Our company can provide a kind of anti-block joint to solve this problem.
Manual Ball Valve
The manual ball valve can be opened periodically flush the tank to remove impurities.
External Heating Bar
A heating bar is used in cold area.It heats at low temperature automatically and stop heating at appropriate temperature to prevent condensate water in the drain valve from freezing.
