Piezoelectric valve

The MV-112 is a precision gas flow valve that uses a piezoelectric bender element as a seal actuator. The bender element responds in milliseconds with precise movements directly proportional to a 0-100-V DC signal, suiting it to closed-loop flow or pressure control systems. It can also be manually controlled with any 0-100-V DC power supply. Features of the MV-112 include fail-safe operation, an externally adjustable seat to allow threshold voltage to be adjusted, a 7-?m filter on the inlet, standard Swagelok or VCR fittings on inlet and outlet ports, and rugged all-stainless-steel construction with Viton seals.
