The VSO® Low Flow valve provides enhanced flow control for applications where precise control flow control is required between 0 – 500 sccm. Like the VSO miniature proportional valve, the VSO® Low Flow miniature proportional valve provides precise flow control of gas in proportion to input current. The valve can be controlled with either DC current or pulse width modulation along with closed loop feedback to deliver optimal system performance. Together with its ability to provide precise control over a wide range of media, the VSO® Low Flow miniature proportional valve is ideally suited for manufacturers of Gas Chromatography and Mass Spectrometry equipment.
The VSO® miniature proportional valve provides enhanced flow control for applications where precise control flow control is required up to 56 slpm. The VSO® miniature proportional valve provides precise flow control of gas in proportion to input current. The valve can be controlled with either DC current or pulse width modulation along with closed loop feedback to deliver optimal system performance. Together with its ability to provide precise control over varying temperatures and media types, the VSO® miniature proportional valve is ideally suited for manufacturers of medical and analytical equipment.
The Lone Wolf miniature proportional valve is a thermally compensated 2-way normally open (NO) proportional valve designed to maintain accurate and repeatable flow over a wide range of media. With the highest performance characteristics of any NO proportional valve available on the market, the Lone Wolf miniature proportional valve is an ideal choice for medical devices and patient monitoring applications that require rapid response along with stable and accurate performance.
The MD PRO is a miniature 2-way normally closed (NC) proportional valve that controls gas flow proportionaly to input current for flow rates up to 56slpm. When used with closed loop feedback, the MD PRO is an economicalsolution that provides repeatable pressure and flow control. The MD PRO is ideal for applications such as respiratory therapy, anaesthesia delivery and patient monitoring devices.
The HF PRO is a miniature 2-way normally closed (NC) high flow proportional valve that controls gas flow proportionaly to input current with flow rates up to 60 slpm at 50 psig. The valve can be controlled with either DC current or pulse width modulation along with closed loop feedback to deliver optimal system performance. The HF Pro miniature proportional valve is an ideal choice for applications that require repeatable pressure and flow control such as respiratory and patient monitoring applications.
The Porter Model EPC Electronic Proportional Control Valve is an electromagnetically-actuated, proportional control valve designed for use in closed loop flow or pressure control systems. When coupled with a flow sensor or pressure transducer and a proportional electronic controller, Model EPC is capable of providing steady and precise control of gas flow rates or pressures. The Model EPC is a DC-driven, normally-closed valve which includes an elastomeric valve seat to provide bubble-tight shut-off. A broad range of flow coefficients (Cv’s) is available for either flow or pressure control.
The Model EPC is offered with either integral compression fittings for in-line mounting or as a manifold-mount version. To allow design and user flexibility, custom configurations in OEM-scale quantities are also available.
The Porter Models 001, 002, and 003A Mass Flow Control Valves are normally closed, proportional solenoid control valves. When coupled with a Porter Mass Flowmeter, a closed-loop control system is achieved which permits separate component (flowmeter and control valve) configuration.
