There is no single solution to meeting these challenges. Malema’s expertise and experience with fluid handling and control will help you to create a custom solution for your process.
Experienced in sensors, electronics, and process instrumentation, Malema incorporates groundbreaking state of the art technologies into every instrument.
The M-100X Series is an extremely sensitive explosion-proof flow switch. It has been engineered to monitor vital sample flow parameters for instrumentation in process control and inert blanket gases. It is used as an auxiliary alarm monitor for flow meters.
The M-VF Series Safety Excess Flow Valves are engineered for fast automatic shut-off in case of line, hose, or fitting failure protecting plant, personnel, and instruments. Designed for protection of systems handling corrosive, toxic, radioactive, and flammable materials; the valve will instantly detect surges in the system and stop fluid flow. The M-VF Series operates effectively with all fluids, liquids or gases.
The M-50X Explosion Proof Series low flow, flow switches monitor increasing and decreasing flow. They utilize a single moving part which responds to fluid (liquid or gas) flowing within a system. The flow monitors operate only when fluid is positively established.
The operating principle is based on a free floating magnetic piston which responds only to the motion of fluids within the line, not to static or system pressures. In the presence of fluid flow, controlled movement of the piston actuates an external hermetically sealed reed switch. This switch can be used to actuate audible or visual alarms, as well as relays, or other controls. The piston's movement can be seen through the PFA body.

Fixed setting PTFE flow switch with in-line flow
The M-701 offers low cost flow monitoring with a variety of switch actuation points and low pressure drop. M-701 is designed for ease of maintanance, as the bonnet and shuttle can be removed, leaving the housing and pipe work connections intact. All wetted parts are
polypropylene or stainless steel, making this switch ideal for a wide range of chemical and temperature requirements.
The M-VF-F Series pressure relief valve is designed with an all-PFA molded body suitable for semiconductor, ultra-pure water and aggressive chemical applications.
