Parker Sporlan Division
Modulating Three Way Valve The Parker Sporlan Modulating 3-Way (MTW) valve allows control of refrigerant flow through two outlet ports. Two valve pistons are attached to a connecting rod and also to the stepper motor. As the MTW valve modulates, one port opens and the other port closes. The movement of the valve pistons relative to the two ports is inversely proportional. The MTW is constructed from a forged brass body for durable field operation, and uses a high quality 42 mm stepper motor. Features/Benefits: * Improved...

ODG (Origin Data Global)
HDMI Modulator: Definition & Features Understanding HDMI ModulatorsWhat are HDMI Modulators?. An HDMI modulator is a device that receives a high definition multimedia interface (HDMI) signal and modulates it into a radio frequency (RF) signal. The modulation is important because of how RF signals can be distributed over coaxial cables, enabling the distribution of HD content to various locations using coaxial cables. An HDMI modulator can be thought of as a translator, as it takes the language of HDMI and speaks in coaxial cable...
