Stainless Steel Cartridge valves according to DIN44 The valves are designed for use with water, water and oil emulsions, oil and gases. Their roust construction and compact design provide long life, ease of maintenance, and high performance. These slip in cartridge type valves can e comined in many different ways to satisfy the requirements of a wide variety of applications. The sealed poppet design provides drop tight, leak free shut off. Product range: Cartridges for directional functions Soft seated ND0 to 00 for water, oil and pneumatic applications up to 50ar Soft seated ND0 to 50 for water, descaling water and oil up to 50ar Soft seated ND0 to 40 for water, oil and pneumatic applications up to 800ar ND 6 to water and oil up to 50ar Cartridges for pressure relief functions ND 6 to for water and oil up to 50ar Cartridges for pressure reducing functions ND 6 to for water and oil up to 50ar E..

Functional description These valves are designed for use with special fluids: No metal to metal contact at the sliding surfaces. the use of non-luricating mediums is possile. All pressurized areas are separated y soft seals for thin fluids and gases under high pressure. Special geometry and non-corroding material for water and descaling applications. An important dimension for the function of cartridge valves is the surface ratio of the seat area Aa and the annulus area A to the pilot area Px. By using a surface ratio of : the valve can e operated only in one direction. By using a surface ratio of :.6 or : the valve can e operated in oth directions, ut cannot e used for pressure functions ecause of the pressure ratio which creates pre-opening of the pilot valve. Soft-seated valves are suitale for use in shut-off and directional functions. These valves are asolutely leak-free even for long-term operation in gas or high-pressure circuits. valves are suitale for use in pressure control functions. Because of their roust seats they can e used also in high pressure water hydraulic circuits.

High pressure valve Type 6D / H Size ND 06 to 040 for water and oil. These valves are designed for pressures up to 800ar. Pressurized opening and closing is possile with the following pressure ratings: Oil up to 800ar. Water with more than 5% oil up to 600ar. Water up to 500ar. Compressed air up to 800ar (nozzle in seriesl necessary) Because of the stronger wall thickness the flow rate is reduced. For calculation please use the following flow curves: ND 6 = flow curve ND 0 ND 5 = flow curve ND 6 ND = flow curve ND 5 ND 40 = flow curve ND Descaling valve Type 6D / Z Up to 50ar - ND 06 to 50 ND 6 00mm area ratio : ND5 50mm area ratio :.6 for water, descaling water and oil Manual operated Valve Type 7D Up to 50ar - ND 06 to 50 for Water and Oil These valves are designed for shut off functions. The servo system reduces the necessary manual power so that the valve can e operated under high pressure. The manual spindle locks the piston in closed position even under pressure.
