Honeywell RP670A1019 Pneumatic SPDT Switching Relay, 13-17 PSI, 5/32″ Barb

Description

Honeywell RP670A1019 Pneumatic SPDT Switching Relay Overview

The Honeywell RP670A1019 is a single-pole, double-throw (SPDT) pneumatic switching relay engineered for commercial and industrial HVAC control systems. When pilot pressure changes, this relay automatically blocks, diverts, or bleeds pneumatic air lines — making it an essential component for reliable pneumatic control sequencing in building automation and air handling applications.

Key Features

• SPDT relay action: block, divert, or bleed pneumatic air lines on pilot pressure change
• Switching pressure range: 13–17 PSI for precise pneumatic control
• 5/32″ barb fittings for secure, leak-resistant tubing connections
• Operating temperature range: 0°F to 140°F for broad environmental compatibility
• Operating humidity range: 5–95% RH for use in diverse HVAC environments
• Compact block-style housing for easy panel or field mounting

Applications

• Commercial HVAC pneumatic control systems
• Air handling unit (AHU) pneumatic sequencing
• Building automation systems utilizing pneumatic actuators
• Switching between pneumatic control branches based on pilot signal changes
• Bleed or divert functions in multi-zone pneumatic control networks
