Series SVP Proportioning Solenoid Valve Low Cost, Stainless Steel Construction 0-24 VDC Input The Series SVP is a low cost, uniquely designed solenoid valve which controls or regulates flow in proportion to a variable voltage input. While most solenoid valves simply provide on/off service, this unit adds a totally new dimension to solenoid valve performance. Reaching to a 0-24 VDC input signal, the valve opens in proportion to the voltage applied, delivering just the right amount of flow needed. Compatible with a wide range of gases and liquids, this unit provides the solution to even the most demanding applications like process control, chemical mixing, high tech manufacturing and laboratory testing. Add a downstream sensing element and Dwyer Series 1600 Process Controller and you have a complete closed loop control system. Another quality feature of this valve is it's tight shut-off (NC) when de-energized.
