GENEBRE SOLUTIONS FOR STEAM

Genebre, a worldwide leader in valves and fittings for fluid control and high-quality taps celebrates its 40th anniversary this year. The company’s industrial line features a wide range of Solutions for Steam.

Highlights amongst the latest innovations are two new Pilot-operated pressure-reducing valves (Ref. 2274 and 2275) for steam or compressed air applications, featuring threaded ends in accordance with ISO 7-1 (EN 10226-1).

The body is made of EN 1.0619 (WCB) carbon steel and the maximum allowable pressure is 25 bar. The maximum upstream operating pressure for saturated steam is 17 bar and the downstream pressure adjustment range is from 0.5 to 12 bar (single spring). The maximum differential pressure is 17 bar and the working temperature is between 0ºC and 260ºC.

All heating processes tend to require steam at lower pressures than those distributed through the boiler. Pressure reducing valves are used to reduce steam pressure to the value required by the process. Pilot-operated pressure-reducing valves work through a pilot valve to load a piston or diaphragm, which increases the internal force used to open the main valve. This allows a higher flow capacity with a smaller pressure difference or pressure drop. Because the downstream force is amplified through the use of the diaphragm, a small change in the pilot valve opening represents a large change in flow and pressure downstream through the main valve.

The main advantages of this type of valve over direct acting valves are higher pressure flows, faster response and more stable pressure control.
