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
