Precise Pressure Calibration: Rated for an 8-11 psi range to ensure accurate valve modulation
Reliable Ignition: Ensures stable ignitor positioning for consistent flame sensing and ignition cycles
Precision Machined: Ensures a perfect 45-degree SAE flare seat for metal-to-metal sealing
This ACR tube fitting is compatible with copper
ensuring that the pneumatic actuator can modulate the stem without premature wear or friction-induced failure
Johnson Controls DMPR-RS311 Fusible Link Precise Pressure Calibration: Rated forAs a direct replacement for the legacy DMPR RS201, the Johnson Controls DMPR RS311 is a critical fire safety component engineered specifically for FD 1300 Series dynamic multi blade fire dampers. This 165 degree fusible link is designed to provide thermal triggered closure in high velocity HVAC systems, ensuring compliance with UL 555 and NFPA 90A standards. The DMPR RS311 functions as a mechanical release; once ambient temperatures reach 165F (74C),
