S21 DIRECT-ACTING PRESSURE REGULATOR

The S21 is a direct acting pressure reducer with balanced piston, designed for low, medium and high pressures. It is suitable for domestic and industrial applications in natural gas, industrial gas, LPG and non-corrosive liquids

Thanks to the sustainable system concept, the following features were achieved:

• High and accurate flow rate (even at maximum flows);
• High accuracy in the closure zone and pressure regulation;
• Fully enclosed – no internal leaks;
• Reduced response time.

The S21 pressure regulator is classified as "Fail to Open" type according to European standard EN 334.

The S21 pressure regulators feature a top entry design (inspection opening from the top), which allows maintenance work to be carried out without having to remove the body from the pipeline.
