Features

1. The discharge temperature can be adjusted when the pipe network is running, and the sensible heat in the high temperature condensate water can be effectively used, and the energy saving effect is remarkable.

2. Water shock resistance, excellent air discharge performance.

3. No noise during operation, which is conducive to protecting the environment.

4. At the beginning of steam, the valve is fully opened, and the low temperature condensate and air are quickly discharged, shortening the start-up time of the equipment.

5. All internal parts are made of stainless steel, resistant to corrosion and cavitation.

6. Compact design, convenient installation and maintenance.

Application: Used for steam main, steam tracing pipeline, radiator, low temperature heating tank, sandwich pot, heating, etc

Working condition adjustment

1. The working state of the product is set according to the steam pressure of 5bar.

2. The working state can be adjusted online according to the actual working conditions and process requirements: turn the adjusting plug clockwise, reduce the discharge temperature, and the valve opening becomes smaller until the valve is closed; Turn the spigot counterclockwise, the discharge temperature increases, the valve opening becomes larger, until the direct discharge steam.

3. Adjustment method: In the case of keeping the steam supply in front of the trap, unscrew the valve cap, loosen the adjustable female, and turn the adjustable bolt with a screwdriver. After the adjustment, tighten the fuse and then the valve cap.
