Setra 2301050PD3V11BC 3-Valve Pressure Transmitter Manifold 4-20Ma Viton 0/50PSI

The Setra 2301050PD3V11BC 3-Valve Pressure Transmitter Manifold is designed to sense and send pressure information from an HVAC system to a controller with a 4- 20mA analog signal. This valve stops the process pressure during maintenance, the equalizing valve equalizes high and low side pressure for easy calibration, and the vent valve traps pressure safely. It changes the pressure transmitter without stopping the entire system. A pressure range of 0-50 PSI is better for keeping monitor on chillers, boilers, and air handling units.
