Product Description
Structural characteristics and applicationsThe PRV1000 series steam pressure reducing valve is a piston type guided actuation pressure reducing valve. Can be used in places with high frequency of usage from small to large traffic, with a simple and sturdy internal structure.1. Compared with previous pressure reducing valves, the operability and durability have been greatly improved. (Compared to our company's products, it is twice as much)2. The main valve has a spherical surface, high sealing performance, and minimal leakage (compliant with ANSI Class 4)3. The gasket is made of non asbestos material.Shell materialDuctile ironValve body nominal pressure and maximum operating temperatureValve body design pressure: PN16Ductile iron: ≤ 232ºCSpecifications and ConnectionsDN15-DN100 flange connection PN16DN15-DN100 flange connection JIS10KPressure reduction ratio and pressure control rangePressure reduction ratio 10:10.1bar-10barExternal dimensionsCaliber | National standard (L) | Daily Standard (L) | C | D | Weight |

Installation precautions
1. The front end of the 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.
