Design Considerations Construction, The M 50X Series comprises a Body piston and Retaining rings Selecting a flowswitch begins with selecting the body. this series is available in 316 Stainless Steel The M 50X series contains one moving part i e the piston and two retaining. rings that are in the fluid path Construction of the piston is important from a design perspective We manufacture three. types of pistons it is critical to select the correct piston for your application 316 Stainless Steel PTFE encapsulated and. Special All Metal Piston, 1 The standard piston is a 316 Stainless Steel piston with epoxy to hold the magnet in place This piston is recommended. for non aggressive fluids and inert gases Stainless Steel retaining rings are typically used with this piston type. 2 The second piston that is available is a PTFE Encapsulated one The piston is a magnet that has PTFE molded around. it and then machined to the appropriate configuration These pistons are primarily used in PTFE flow switches and also. in other flow switch bodies typically 316SS and Acrylic bodies where customer prefer a piston that does not have epoxy. in the fluid path as well as a piston that is impervious to aggressive fluids and gases This piston is highly recommended. for medical applications Hysteresis on these pistons does tend to be slightly higher 10 to 15 than metal piston due to. frictional effects weight and surface adhesion considerations Prior to selecting this piston fluid temperatures and fluid. compatibility with PTFE must be taken into account because certain aggressive chemicals at specific temperatures tend to. swell PTFE causing the piston to change shape resulting in failure of the product Stainless or PTFE retaining rings can be. used with this piston, 3 The third piston that is available is a Special All Metal piston with no epoxy only available in 316SS This piston is fabricated. in a proprietary process with only one weld seam leak tested which presents an all 316SS surface to the fluid path This. piston is recommended for those applications where the piston could experience a lot of cycling wear This piston has been. tested to 250 000 cycles at 125 psi Stainless Steel retaining rings are recommended for this piston type for low pressure. applications and an orifice disc See Universal Mounting Diagram is recommended for high pressure 125 psi applications. Fixed Flow Setting Information, This model is a FIXED flowswitch The flow set point is fixed at the factory and is NOT field adjustable Proper calibration of. the set point requires the following information When purchasing a flowswitch use the Flow Switch Application Sheet. or provide the following information on the purchase order. Calibration set point Please indicate if standard or actual. Increasing or decreasing flow,Fluid type i e liquid or gas.
Density and or specific gravity,System pressure and temperature. Flow direction i e upward or downward,Mounting orientation i e horizontal or vertical. malema com,malema com,M 50X Explosion Proof Fixed Flow Switch.
