Features

1. The sealing surface adopts a spherical structure, and has good sealing performance.

2. The bimetal sheet is made of imported materials, with high sensitivity and strong and durable.

3. The discharge temperature can be adjusted according to the requirements of the working conditions, and the sensible heat in the high-temperature condensate can be effectively utilized, and the energy-saving effect is good.

4. There is always high-temperature condensate in front of the valve, forming a reliable water seal and no steam leakage.

5. Water hammer resistance, excellent air exhaust performance.

6. The valve adopts advanced reverse sealing structure, which can prevent the condensate from backflowing.

7. At the beginning of steam ventilation, all the valves are opened, and the low-temperature condensate and air are quickly discharged, which shortens the starting time of the equipment.

8. The internal parts are made of stainless steel, which is resistant to corrosion and cavitation.
