Pressure reducing valve, direct acting with balanced seat

Vartsila manufactures direct acting pressure reducing valve with balanced seat. This is a valve that protects household water installations for industrial or commercial applications. Use of pressure reducing valve protects damage to the installation caused by pressurization and also reduces water consumption. Spring-loaded pressure reducing valves operate by means of a force equalizing system. The force of a diaphragm operates against the force of an adjustment spring. If the outlet pressure and therefore diaphragm force falls because water is drawn, the then greater force of the spring causes the valve to open. The outlet pressure then increases until the force between the diaphragm and the spring are equal again. The inlet pressure has no influence in either opening or closing of the valve. Because of this, inlet pressure fluctuation does not influence the outlet pressure.Technical specifications: medium - water and compressed air; inlet pressure - maximum 20.0 bar; outlet pressure - 1.0 - 6.0 bar; connection size - 1/2-inch to 2-inch; and end connections - screwed. Special versions are available on request - with built-in filter or without.
