Overview

The MKS Instruments 154 High Flow Control Valve offers better response time as compared to other high flow control valves. This is possible through the use of a "balanced forces" design that automatically neutralizes the pressure-induced imbalances within the valve. The elastomer-sealed 154 valve is designed for flow rates from 0.2 to 200 slm.

316 S.S., Nickel and Viton® wetted materials (other seal materials optional)
20 to 200 slm full scale flow ranges
½” Swagelok®, 8 VCR, or 8 VCO® male fittings

Features

Flow Valve Controller

The 250E is a self-contained PID pressure and flow control module designed to provide optimized control of the total pressure or flow of a gas (or gases) in a dynamic closed-loop system. With the 250E, input can be supplied by a Baratron® Capacitance Manometer or other compatible vacuum gauge for closed-loop pressure control, or flow input can be measured by a mass flow transducer for closed-loop flow control. Its power supply has sufficient output to power most capacitance manometers and flow valves. Process control can be manually adjusted through a front panel potentiometer or remotely programmed with a 0-5 VDC analog signal for profile generating.
