Direct acting pressure-reducing valve

Direct acting pressure reducing valve is a new product launched by Vartsila. These spring-loaded pressure-reducing valves operate by means of a force equalising system. The force of a diaphragm operates against the force of an adjustment spring. If the outlet pressure and therefore diaphragm force fall, then the 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. The valve insert is of high quality synthetic material. The valve has in-built provision for inserting pressure gauge. Servicing and maintenance of the valve is possible without removal from pipe work. Integral filter with easy clean attachment is the optional feature. These pressure-reducing valves protect household, industrial and commercial water installations within the range of their specification.
