Springs for valves - Import export

The diaphragm dosing pumps in the MEMDOS MR series have been developed for a wide range of applications in dosing technology. They are ideal for use in industry, process engineering, water treatment and waste water treatment. Features: . Robust dosing head: Made of PP and stainless steel for high durability and longevity. . Precise dosing: Double ball valves (up to MR 290) and spring-loaded flat-seat valves (from MR 290), optional spring-loaded single ball valves. . Safety: Separation chamber with drainage tube between dosing head and gearbox protects against leaks. . Flexible stroke adjustment: Can be adjusted manually or electrically (ATE). Optional extensions: . Dual dosing pumps for increased performance. . Stroke counting with inductive sensor for precise batch processes. . Frequency inverter control for variable control.

The pressure relief valves GEMÜ N085 and N185 protect the plant and the piping system against gauge pressure and reduces pressure peaks. The third pipe spigot enables the valve to be installed in the main pipe. If the pressure increases, the spring is raised and the valve opens. The pressure is reduced to the preset value and can escape via the third pipe spigot into an adjacent pipe. If the pressure falls, the spring force presses the diaphragm in the direction of the seal seat and it is closed. The spring force can be adjusted as required using a set screw. - Valve adjustments can also be made under working pressure. - The optimization of piston, springs and control face ensures good control characteristics - The actuator is hermetically separated from the medium

The GEMÜ N082, N182 and N782 pressure reducers ensure that a constant outlet pressure is maintained in process plant utilizing the pressure differential.If the pressure rises on the outlet side, the spring force is lower and the valve closes as the spring is raised. The pressure is reduced until the spring force and the outlet pressure are the same. If the pressure falls, the valve opens as the spring force presses against the diaphragm surface via the control aperture. The outlet pressure can be read off a diaphragm-protected pressure gauge (not available for N782) and the spring force adjusted using a set screw as required. - The working pressure can be very easily adjusted using a set screw and secured with the integrated lock nut. If required, the setting that has been made can be lead sealed - The flow-efficient design of the valve body ensures good flow rate values - Control errors are kept to a minimum due to the large control face and the spiral spring

General purpose type with stainless steel body and rubber seal. Electropolished body for enhanced corrosion resistance. Body and valve springs are stainless steel (SUS304, SUS316). Body is electropolished for enhanced corrosion resistance. Seal materials can be selected to suit your fluid and application, to flexibly comply with your semiconductor production process requirements. Abundant size variations allow choice to suit your application and flow rate. Each plug comes with a dust cap.

• Seat principle, direct actuated; • Frictionless movement Spider µProp-valves are real proportional valves, in which the armature stroke is proportionally defined by the infinitely-variable current applied. The constant ratio between armature stroke and flow rate thus allows variation of the flow rate by way of the applied current. Spider µProp-valves are like Spider on/off valves microvalves The anchors installed in the micro valves have the shape of a disk. In energized status, this so-called flat armature is pulled against the magnetic yoke component group. If the coil is deactivated, the leaf spring joined to the flat armature presses the seal positioned on the spring-armature assembly unit against the valve seat. These quick-acting valves owing to the small mass of the installed armature achieve switching phases in the millisecond range. These valves have a capacity of up to 4 billion actuations, depending upon operation mode.

• Sizes: Ø 7 mm, Ø 15 mm, Ø 21 mm; • Application: Neutral and mildly aggressive liquids, gases and vapors; • direct actuated; • 2-way valves and 3-way valves, NC; Spider valves are allocated to the micro valve category (outside diameter 7 mm). The anchors installed in the micronized valves have the shape of a disk. In energized status, this so-called flat armature is pulled against the magnetic yoke component group. If the coil is deactivated, the leaf spring joined to the flat armature presses the seal positioned on the spring-armature assembly unit against the valve seat. These quick-acting valves owing to the small mass of the installed armature achieve switching phases in the millisecond range. As these valves predominantly featuring cartridge connections have an almost frictionless armature movement, they have a capacity of up to 4 billion actuations, depending upon operation mode. Spider valves may also be triggered via so-called pulse width modulation.
