Unlike standard steel valves

Leak Prevention: High-density material reduces the risk of pressure signal loss

Using it in non-specified actuators may lead to improper valve sequencing or failure to close under pressure

Enables precise gas pressure adjustment to meet the specific BTU/h demands of high-capacity appliances

using it with larger series like the AF or smaller TF series is not recommended

Belimo S2A Auxiliary Switch Els PW 17895 Unlike standard steel valvesThe Belimo S2A auxiliary switch is engineered for precise position signaling and versatile switching functions within HVACR systems. This robust add on unit features a 2x SPDT (Single Pole Double Throw) configuration, providing reliable feedback for damper and rotary actuators. With a switching capacity of 3A (0. 5A inductive) at 250 VAC, or 0. 5A (0. 2A inductive) at 110 VDC, it integrates seamlessly into various control sequences. Installation is
