ER25 Bell shaped Float Inverted Bucket Drain Valve

1、 Characteristics and performance of ER25 bell shaped float inverted bucket steam trap:

1. It has strong adaptability to the occurrence of condensed water, and can be discharged intermittently or continuously.

2. Internally equipped with a large displacement dual seat differential pressure mechanical and SCCV closing system, it has a small volume but a large displacement.

3. All internal components are made of stainless steel and installed on the valve cover, making maintenance and repair extremely convenient.

4. High back pressure rate: 90%

5. Reliable separation of steam and water: (Water vapor enters from the lower part of the valve through a U-shaped channel), the valve is always in a water sealed state, and there is x to prevent steam leakage.

6. The open mouthed float is resistant to water hammer, and the bucket is equipped with overflow exhaust holes to prevent steam lock and air blockage. (Non condensable high-temperature air can also be excluded)

7. Combined with lever machinery, a high-pressure valve can be made.

2、 ER25 bell shaped float inverted bucket steam trap double seat differential pressure mechanical and SCCV closing method:

The SCCV closing method and double seat differential pressure mechanical installation in the same unit have a long service life. When the condensate volume increases, the bucket loses buoyancy, causing the mechanical reverse seal to generate pressure difference. The main valve opens to obtain a large displacement, and the steam equipment is quickly started to maximize the thermal efficiency of the machine.

3、 Main parameters:

Valve body material: carbon steel, stainless steel, etc

Internal material: stainless steel

Caliber: 15-150mm

Temperature: 0-425 ℃ (carbon steel), 0-525 ℃ (stainless steel)

Pressure: 1.6Mpa-4.0Mpa

Allowable back pressure rate: 80%

Connection methods: flange, thread, welding, etc

4、 Selection Notice

1. Condensed water load (discharge volume) KG/H (selected ratio 2-3 times)

2. High work pressure

3. Work pressure difference

4. Valve body material

5. Connection method

5、 Usage and maintenance

1. It should be confirmed whether the material, pressure, and temperature of the valve body can meet the requirements of the working conditions.

Before installation, the pipeline must be cleaned to remove impurities.

3. The installation location should be as close as possible to the heating equipment.

4. Install horizontally at the low point of the pipeline, with the flow direction consistent with the direction marked on the valve body.

5. Each heating device should be equipped with its own drain valve to avoid mutual interference.

To ensure the normal operation of the system, slowly open the valve in front of the drain valve and gradually raise the temperature to a normal state.

7. Regular maintenance is required to ensure the normal operation of the drain valve.
