Self-operated High-pressure, Large-flow 461 - 57S Series
The 461 - 57S large-flow, medium and high-pressure self-operated pressure regulator has reliable regulation, safe operation, and fast response. It does not have the complex maintenance of pilot-operated pressure regulators. Installation, adjustment, and maintenance are extremely easy.
- Maximum inlet pressure can reach 7MPa
- Maximum outlet pressure can reach 0.7MPa
- Maximum flow rate reaches 35000Nm³/h
Main features of the 461 - 57S self-operated pressure regulator with rolling diaphragm:
- Direct-acting pressure regulating valve
- High pressure regulation accuracy
- Optional double-seat structure, small installation space, large flow capacity
- The structure of the balanced valve core makes the outlet pressure more stable and insensitive to changes in inlet pressure
- High-performance noise reduction design
- Ideal for monitoring purposes
- The rolling diaphragm makes it easier to operate than ordinary self-operated pressure regulators, with fast response speed. Installation, commissioning, and maintenance are extremely easy. It overcomes the drawback of pressure fluctuations in the downstream caused by the "sagging" of the diaphragm of ordinary self-operated regulators, and also overcomes the drawback of diaphragm damage of ordinary self-operated regulators.
- Simple pressure setting
- Can be repaired online
- Applicable to natural gas, liquefied petroleum gas, air, CO₂, nitrogen, and other non-corrosive gases
- Multiple connection methods: 2" NPT/ANSI 150RF/250RF/300RF/600RF flanges
- Mainly applicable to high-pressure, high-power occasions, such as city gate stations and city gate boundary stations, regional and zonal pressure reduction systems, gas distribution systems, transmission systems, high-power industrial combustion systems, monitoring systems, etc.
