Ashcroft B428VXFT-200 Pressure Switch 0-200 PSI

The Ashcroft B428VXFT-200 Pressure Switch is a control part that monitors system pressure and automatically changes electrical contacts when the preset pressure threshold is reached. Featuring a 0200 PSI adjustable operating range, it allows pressure settings to be configured for applications requiring accurate monitoring and control within HVAC systems. An internal pressure-sensing element responds to changes in system pressure and actuates the switching mechanism for connected equipment. The switch mounts to a compatible pressure connection and integrates with the control circuit to coordinate system operation. Accurate pressure response promotes stable equipment control, consistent operating conditions, and dependable system performance.
