Multiple-Port Valve Is Appropriate for High-Purity Environments
The Robolux valve is suitable for hygienic-processing facilities in the pharmaceutical, chemical, food and beverage, and similar industries where cleanability is important. The multiport valve and manifold design enable one membrane to handle two independent process-switching functions, which allows one of these valves to replace two traditional shut-off diaphragm valves. This, plus the elimination of T-adapters and dead legs, reduces installation space requirements. The internal volume of the valve has been minimized to improve flow and evacuation properties, as well as reduce unnecessary waste of expensive chemicals and ingredients. Fieldlevel automation is possible with components that include pilot valves, electrical feedback units, and optical status indicators; up to 62 valves can be connected to a programmable logic controller (PLC) by a two-wire line connection. With all of the necessary automation controls contained in the head of the valve, installation and maintenance are made quicker, simpler, and less expensive. An LED optical status display integrated into the control head aids diagnostics and maintenance by signaling the current switching position of the process valve.

Diaphragm Valves Have High Flow Coefficients
The Type 514-519 high-flow diaphragm valves have an optimized, turbulence-free flow geometry and flow coefficient (Cv) values that are, on average, more than double those of traditional diaphragm valves. This increases flowrate performance and reduces energy consumption, which makes these valves suitable for applications where diaphragm valve use has typically been limited due to flow restrictions. A self-draining feature minimizes dead space and improves hygiene and resistance to crystallizing fluids. The body is attached to the bonnet by a metal-free threaded connection that minimizes buildup in corrosive environments and eliminates the need to retorque bolts due to thermal expansion. The valves come in sizes of...
