PRV2S Direct Acting Pressure Reducing Valve

Specifications

Taian, as a professional R&D and manufacturing factory of PRV2S direct acting pressure reducing valve in China, specializes in mass production, strict ISO quality control and OEM/ODM service.This pressure reducing valve is used for pressure reduction at the boiler outlet, steam distribution pipelines, etc. It is applicable to equipment such as sterilizers, humidifiers, and small heat exchangers that require reducing steam pressure. PRV2S direct acting pressure reducing valve is suitable for applications where the load is relatively stable and the accuracy of pressure control is not highly demanded.

Dimensions

Structural characteristics and applications

PRV2S direct acting pressure reducing valve suitable for use in steam or compressed air systems. The direct acting structure is simple and most suitable for branch pressure control and small steam equipment

1. The valve seat components are made of high-quality stainless steel and alloy steel, which are durable, wear-resistant, and have a long service life

2. The pressure sensing adopts an external pressure corrugated tube, which can maintain excellent performance and durability for a long time

3. Secondary pressure regulation can be easily adjusted through a handle without the need for other tools

4. The built-in filter can effectively prevent impurities from biting into the valve seat components.This product is precise and reliable, capable of reducing steam and air from high pressure to the effective working range of the equipment, and preventing equipment damage.

Shell material

Ductile iron

Valve body nominal pressure and maximum operating temperature

● Valve body design pressure: PN16

Specifications and Connections

DN15-DN25 threaded connection PN16

Pressure reduction ratio and pressure control range

● Pressure reduction ratio 10:1
● Provide three different colors of springs to control downstream pressure:
● Grey: 0.14 bar g-1.7 bar g
● Green: 1.40 bar g-4.0 bar g
● Orange: 3.50 bar g-8.6 bar g

Installation precautions

1. The front end of PRV2S direct acting pressure reducing valve should be equipped with a steam water separator, and a drain valve should be installed at the bottom of the steam water separator.

2. The front-end should be equipped with a filter with a mesh size of 100.

3. Install bellows globe valves before and after the pressure reducing valve, and choose full bore globe valves to ensure rated flow and good control.

4. Pressure gauges should be installed before and after the pressure reducing valve.

5. The pressure reducing valve pipeline should be equipped with a bypass, and the equipment can be used for maintenance of the pressure reducing valve without shutting down.

6. When selecting a safety valve, the maximum flow rate of the pressure reducing valve should be considered when the safety working pressure of downstream equipment jumps, because the reseating characteristics and pressure reducing valve should be considered when the pressure reducing valve fails.
