They control the pressure downstream of the valve without requiring pneumatic or electrical control elements. The pressure reducing valve DM 668E is a diaphragm-controlled, spring-loaded proportional valve for medium flow rates. The valve has been made of deep-drawn titanium grade 2 with excellent corrosion resistance. The pipe-shaped inlet connection of the casing has been provided with the seat bore. The soft seal cone is guided in the seat part and is connected with the regulating diaphragm. The valve can be manually shut off by means of the hand wheel. The spring module comprising spring cap, spring, adjusting screw, diaphragm and internal components, is connected to the valve body only by means of a clamp ring and two bolts. Changing the diaphragm or the complete spring assembly for a different control pressure range is extremely simple and does not call for special tools. The same applies to servicing and maintenance. Standard » » » » medium wetted parts made of Titanium spring cap made of CrNiMo-Stahl quick-release body clamp ring non rising adjusting screw Options » a variety of connections with fire hose couplings typical for the country in question » special versions on request Operating instructions, know how and safety instructions must be observed. All the pressure has always been indicated as overpressure. We reserve the right to alter technical specifications without notice. Kvs values [m3/h] 14 Setting Ranges [bar] 6 - 8,5
