MV-112 - PIEZOELECTRIC VALVE


The MV-112 is a precision gas flow valve which utilizes a piezoelectric bender element as the seal actuator. The bender element responds in milliseconds with precise movements directly proportional to a 0-100 volt DC signal, making it ideally suited to closed loop flow or pressure control systems used in semiconductor or other processes. The MV-112 can also be manually controlled with any 0-100 volt DC power supply. The optional MV-24V provides valve control with a 0 to 24 volt DC signal.

The MV-112 features: fail-safe operation, externally adjustable seat to allow threshold voltage to be adjusted, a 7 micron filter on the inlet, standard Swagelok® or VCR fittings on inlet and outlet ports, and rugged all stainless steel construction with Viton® seals.
